Eilon Engineering 2125 Wired Dynamometer Installation Guide
General Cautions and Warnings
The following cautions and warnings, system specifications, and user instruction sheets should be read carefully before attempting to use this Eilon Engineering product.
Products are supplied with the express understanding that the purchaser and/or user are thoroughly familiar with their correct application and proper use. Eilon Engineering will assume no responsibility for the misuse or misapplication of any of its products.
In addition to these guidelines, the user must also comply with general safe operating practices when using the system e.g. when weighing during lifting.
The load limit rating, a.k.a. capacity, indicates the maximum force or load a system can carry under normal working conditions. Overloading or placing a load on the system above its rated capacity is dangerous and is therefore STRICTLY PROHIBITED except during the system’s annual safety testing. This testing must be performed by qualified personnel and allows the system to be overloaded up to 25% of its rated capacity, no more than once per year.
Filon Engineering will accept no liability for damage caused by the product being used in excess of the working load limit or from abuse.
Opening, attempting to open, or any attempt to repair the system by unauthorized personnel (without written authorization) will nullify the warranty as well as the manufacturer’s liability and could be dangerous. Refrain from doing so and contact an Elion representative should any problem with the system arise.
When measuring loads using a shifted zero with the tare function, the actual load is the value indicated on the readout plus that of the shifted zero or tare.
The system is designed for static loading. Eilon Engineering or other qualified engineering personnel should be consulted before using the system to measure dynamic loads. Avoid bending, twisting, side loading and off-axis loading.
When connecting the load cell in order to measure forces or loads, special care should be taken in choosing appropriate shackles or other connecting accessories that will permit free movement and prevent bending moments and twisting in the load cell.
Always use shackles with a S.W.L. (Safe Working Load) equal to, or greater than the system’s rated capacity.
Check the system thoroughly before use, including the lifting accessories which are included with some Ron systems. Do not use a damaged system.
We recommend that the system is checked occasionally by lifting a known weight. Further, the system should be sent back to the manufacturer or to an authorized service center for general examination once every year.
System calibration should at first be performed annually in an authorized laboratory unless local laws, regulations, or other policies require alternative intervals. Once the user becomes familiar with the particular needs of their system, the need for calibration may vary.
Between calibrations, the user can verify whether the systems are still calibrated correctly by using a known weight.
Calibration verification and adjustment must be performed with extreme care. An erroneous calibration adjustment will result in false readings, which could be dangerous.
If there is any doubt as to the reliability of the load indication, do not use the system with an unknown load. To check its reliability, use a known load preferably with a value of more than 50% and less than 100% of the system’s rated capacity. Never usc a weight that is more that the rated capacity.
The permitted temperature range appears in the Ron system specifications. Do not allow the system to overheat or fall below the minimum permitted temperature, as doing so may be dangerous and cause damage.
Take particular care not to expose the system to nuclear radiation.
Local environmental conditions such as extreme temperatures (those that exceed the stated temperature range in the system specifications), chemical materials, radio
transmissions or other magnetic radiation may interfere with the system’s reliability causing a false reading which could prove dangerous. Avoid using the system under such conditions.
The system is not explosion-proof and should not be used in hazardous arcs Unless otherwise specified, Eilon Engineering products are not legal for trade. Each system consists of a load cell with its own indicator (excluding 1000 & 4000 models).
Important: If you own several systems, make sure that each load cell is used with its original indicator. Load cells and indicators are calibrated as matched pairs and are non-interchangeable.
IMPORTANT:
At all times, it is the responsibility of the user of this equipment to ensure that normal safety precautions are observed. No amount of safety features and engineering can be a substitute for common sense and a desire to work safely.
Ron systems are prohibited by the manufacturer and/or seller to be used in any nuclear or similar site where nuclear and/or radioactivity and/or ionizing radiation (henceforth radiation) exists. Ron systems may not function well in any space where radiation exists. If despite this warning the user uses the system in radiation, he/she is waiving any right of claim against the manufacturer and/or seller concerning direct or consequential damages or loss resulting from the use of Ron systems in violation of the above restrictions, and the user assumes full responsibility and liability to waive any subrogation claim rights by the insurer to such claim against the manufacturer and/or seller. This restriction does not apply to areas that are deemed safe for people to work in.

General Description
Ron Crane Scale and Dynamometer basic information.
The Ron 2125 is available either as a Shackle or Hook Type. The system consists of a Load Cell and an indicator. On capacities of 12.5 ton and up, the indicator can be attached directly to the load cell, thus eliminating the need for an extension cable. The indicator is securely attached to the load cell using a special latch that ensures the unit will maintain a safe and reliable connection..
The system’s indicator can also be detached from the load cell and held by the user. An extension cable designed to connect the two devices is supplied with the unit.
It is recommended that the user either holds the remote indicator in his hand or view the large display from a distance, so that under no circumstances will he have to approach the load in order to read the result. By this means, the user’s personal safety is ensured.
The indicator includes a 6 digit 1″ (25 mm) LCD display and front panel standard with a nine button keypad.
The 2 AA disposable 1.5V alkaline batteries. Continuous operation of the system while using batteries rated 3AH will result in at least 2000 hours of battery life (more than two months). Occasional use will extend the battery life up to several years.
The following are available options:
- Rechargeable batteries (instead of disposable) with a charger.
- IP 67 or IP 68 protective sealing.
- A specially fitted carrying case.
- Digital RS-232 or RS-485 output for communication with computers, printers or data acquisition
- devices. Analog output: 0/1 * V or 0/2 V * 0 + 3V
- Additional 2″ (50mm) and 5″ (125mm) displays.
- Analog output: 420mA, loop.
- User-adjustable set points (1 or 2 Points).
- Totalizer: stores/displays a total of selected loads.
- Automatic/Manual Data Logger: Records measurement to indicator memory for later download to PC. (Up to 50,000 measurements)
- Additional extension cable in 15ft/5m increments
- Dampened (average) display for unstable load
- Rope falls multiplier, user selectable
- Wireless communication to additional display or PC
Basic Operation
Basic operation of Ron systems and helpful tips and tricks
Before operation, be sure the shackles you intend to use are appropriate for the system (see shackle specification table). The indicator can connect directly to the load cell via the short cable on the indicator or with an extension cable. Line up the arrows of the connector plug on the cable and the connector socket on the load cell and apply gentle pressure until locked. To disconnect, pull back the outer ring on the plug, freeing the locking device. With the outer ring pulled back, disconnect the plug and socket. Before use, ensure that the cable is not kinked and can move freely without becoming snagged or caught during operation. Press the 
key to turn the system on. The display will read BATT, then the percentage of remaining battery life followed by the unit of measurement.
M. TON (Metric Tons)
STON (Short Tons, American rons, 2000 Lbs)
LBS
KNTON (Kilo Newton)
DECAN (Deca Newton)
N.WTON (Newton)
KG
The current weight value will then be displayed.
Before loading the system, press Zero 
until ZERO is displayed.
The system should then read GROSS then 0.
Once use of the system has been completed, press the key to power down. Return both the load cell and indicator to their carrying case or another appropriate safe place of storage.
When closing the carrying case, please ensure that the cable is not caught in the edges of the case as this will likely damage the cable. General operation of the keyboard:
When pressing a key, the system responds with a short audio signal (a beep) followed by a change to the display. For example, if one presses the Max 
key, MAX will be displayed. The key should be pressed continuously until the beep is heard. Exceptions are turning the system on or off which does not require a long press. Also, when several keys are pressed in sequence as part of a code during calibration, the visual signal will only appear upon completion of the code, but the beep will still follow each valid key press. If the passcode is not accepted, the display will read COD.E.R. In this case, a new attempt should be made. (See Calibration for more.)
Tare
Switching between Gross and Net modes
The system features a Tare function that enables the user to ensure the display reads 0 even though there may be weight on the system such as from a sling, shackles or a container. This capability makes the system easy to use as it eliminates the need for
the operator to subtract the weight of the container, etc. when only the net amount of the load is required.
To use the tare mode, load the system with the desired container and then press 
. The screen will display NET, then the value of 0. The system is now in Net mode. To exit out of Net mode, press again. GROSS will appear indicating that the system is back in Gross mode. The system will show NET on the screen about once every minute as a reminder that it is in Net mode. Note that switching between Gross and Net modes will clear the MAX (see MAX section).
CAUTION:
When measuring loads using a shifted zero with the tare function, the actual load is the value indicated on the readout plus that of the shifted zero or tare.
Max (a.k.a. Peak Hold)
Checking the maximum registered load value
The system features a MAX (aka PEAK HOLD) function. MAX will store the maximum weight that the system has detected since it was last powered on or since the Gross/Net mode was changed.
Press the key until the display shows :M:AX. It will then display the current maximum load the system has registered since the last time the MAX was reset. The weight will be displayed for approximately two seconds with colons in between the digits. These simply serve as a visual indicator that the displayed value is the stored max and not the current weight. The system will go back to the current value then a beep will sound indicating that the system is ready for a new operation.
The MAX memory is cleared every time the system is powered down or the mode is changed between Net and Gross. If the system is equipped with the user selectable units options, the MAX will also be reset if the unit of measurement is changed (see UNITS section).
Overload Warnings
Two level visual overload warning.
The system features a two level visual overload warning. When loaded to 100% of its maximum capacity and up, the displayed weight will flash on and off continuously. Should this occur, the lift should be terminated immediately and the current load set down.
Should the system be drastically overloaded (130% of max capacity), DANGER (short for danger) will appear on the display. Only when the system is completely unloaded and the measured value reduced to zero will the DANGER message disappear.
Should this occur, it is essential that the Ron system and all accompanying rigging accessories are checked by an authorized inspector before being used again.
Please note that both overload warnings remain functional at the same levels (100% & 130% of full capacity) whether the system is in Gross or Net mode. This means that when TARE is used, you may see an overload warning at a displayed value that is less than 100% of capacity.
All overloads are dangerous to personnel and should be avoided at all costs. Overloading the system can also result in costly damage to the system itself.
Battery Care
Maintenance of Ron 2125 batteries for top performance
The standard system is powered by three AA 1.5V disposable alkaline batteries. They are housed in a battery holder located inside the lower part of the indicator.
Battery compartment should not be opened in rainy conditions.
To replace the batteries, remove the bottom cover of the indicator by pressing on the small buttons with an instrument. Gently remove the battery holder from the indicator being careful not to damage the wiring. Replace the batteries with three fresh AA 1.5V disposable alkaline high quality high energy batteries.
Batteries rated 3AH will result in at least 2000 hours of battery life (more than two months of continuous use). Occasional use will extend the battery life up to several years.
The display will show LO:BAT when the batteries need to be replaced. Once LO:BAT is displayed, you still have several hours of operation left. If the battery level gets too low, the system will automatically power down in order to avoid damage from low voltage.
When the system is turned on, the batteries’ energy level is displayed as a percentage c.g 100%. Battery level can also be checked from the menu.
Rechargeable Batteries
Though we recommend standard alkaline AA batteries, rechargeable batteries are offered. This option includes 3 AA NiMH 2700 mA rechargeable batteries in a battery holder, the same as the standard disposable alkaline batteries (see details above). The system is supplied with a mating charger.
The batteries should be charged:
- Prior to using the unit for the first time,
- Before use, if more than two months have passed since the last charge.
- When LO:BAT (low battery) is displayed on the screen.
A full charge will take 10-14 hours.
Store bought rechargeable batteries may be used. Choose NiMH AA size 1.2V rechargeable batteries (minimum 1800mAH or higher) and a standard charger. Due to the difference in battery voltage, rechargeable batteries will display a biased energy level. For example, fully charged NiMH batteries will only show an energy level of 80% rather than 100% and will normally show a value about 20% less than the actual level.
WARNING
It is dangerous to charge disposable batteries and may result in the batteries exploding. If you are using disposable batteries in a system sold with rechargeable ones, please remove the charger from the system’s carrying case or place of storage in order to prevent potential accidents.
Accessing the battery compartment
Calibration
Performing additional calibration and adjustment to the system
Note
It is recommended that calibration be performed by authorized and skilled personnel only! It should be performed using an accurate known weight or in a laboratory.
Unless otherwise required by local laws, it is recommended that the system be calibrated annually. The weight used in the calibration must not exceed the system’s capacity.
Best Practice for Calibration
It is recommended that calibration and adjustment are performed using a known weight that is 80% of the system’s maximum capacity. This will give the best and most accurate results. A known weight between 80%-100% of capacity may be used but never a weight greater than the capacity.
If the system includes a dampened display/averaging, the dampening should be shut off before calibrating (see Dampened Readings section). The system is protected by two different codes to prevent calibration by unauthorized personnel.
Performing Calibration
Access the Menu:
Press and hold the Menu/OK button.
Using the arrow keys scroll to CALIBR. and press OK
The system will display CODE?
Press ESC + OK simultaneously until you hear the beep.
The system will display CODE?
Press TARE.
The display will show the current units in use e. g Lbs, M. TONS etc. and will then display LOAD.0. At this point all weight/force must be removed from the system.
Once the system is unloaded, press OK. The display will flash WAIT for a few seconds and then L.VALU (load value). This means that the load of a known weight intended for calibration is ready to be applied.
Once the known weight has been applied (lifted), press OK. The display will show APPLY followed by the max capacity of the system. Using the arrow keys AV, set the load value you intend to use for the calibration. If no key is pressed for 8 seconds, the system will exit out of calibration mode and you will have to start again from the beginning. Once the load value on the display matches that of the known weight currently loaded, press OK. The display will flash WAIT and then OK. This means the system has successfully been adjusted and the display will return to the standard measuring screen.
At any time, you may press ESC to exit out of the calibration process. The display will read OK and then revert back to the main measuring screen.

Totalizer with Data Logging (if included)
The totalizer with data logging allows loads to be stored in the system’s memory and sent to a serial printer or PC at a later time. The memory can hold roughly 5000 load values and these can be stored in load groups whose combined totals will be separate from one another.
To store a load in the system’s memory, press TOTAL. The display will then show TOTAL and then N# (this # is the current total number of loads in the memory for the current group of loads). Press ENTER and the display will read ADD followed by N# (this # will be the current load just stored, one number higher than the former N#). Finally it will display the combined total of all loads stored in the group before going back to standard display screen.
A special “filter” in the totalizer program prevents the user from mistakenly adding the same load twice. This is a very practical feature, because if the operator is unsure if he has already added the current load, he just has to try to add it. If it has already been entered, the system will reject it.
This “filter” is based on the fact that a load reading of zero must be sensed by the system in between loads. If the system does not find a zero value before the current load is entered into the totalizer, it will reject it. Zero for this purpose is between 3% and -3% of the system’s capacity: The totalizer will reject duplicate loads by displaying DOUBLE followed by IGNOR.
The system will only accept loads having the same Tare mode i.e. GROSS or NET. If the first load to be entered in the totalizer memory is NET, then no GROSS loads will be accepted. In such a case, ERR.34 will be displayed.
To print or output the stored values of the totalizer, press TOTAL then PRINT. This will print each load separately (of the newest group of loads), followed by their combined total.
The totalizer can store several groups of loads. After one or more loads are recorded into the memory the user may press TOTAL then ESC to start a new group of loads. The display will show NEW. Upon storing new loads, the N# that appears will start again at zero. Whenever TOTAL followed by PRINT is pressed, the system will print the most recent group of loads. By pressing TOTAL then MAX, each group of loads with their individual combined total will be printed, one after the other.
Note that in order to start a new load group, the system must be at a zero reading (between 3% and -3% of full scale). If this is not the case, the DOUBLE/IGNORE message will be displayed.
At any time the user may press TOTAL followed by TOTAL again to see the current sum of loads of the current load group.
To clear the totalizer memory, press TOTAL then RESET.
The totalizer knows how to add loads in different units. It does all the calculations needed to convert the values in the memory to the one you have selected. It is possible to start totalizing loads measured in Lbs and then switch to S. TONS (short tons) or any other available unit and to continue adding loads. The system will display and print the values in the current measuring units. You can even “translate” a load. value you have in the totalizer by switching to a different measuring unit, provided the user selectable units option is included.
Press the TOTAL key to obtain the load value in the new selected measuring units.
Data Logger, standard (manual) (if included)
Notes: The system must be equipped with the RS-232 digital output. The Red Tine Cock lightly Mandal
The standard data logger (D.L) stores measurements in the indicator’s internal memory. Memories are available in 600, 3,000, 6,000 & 10,000 maximum lines of data.
Each single line of data stored in the DI.. memory includes:
- The unit of measurement (Lbs, Kg, kN etc.)
- The tare condition (gross or net)
- The line number in the memory (1, 2, 3 etc.)
If the system is equipped with the optional real time clock, the year, month, day, hour, and minute will be also stored.
Each entry is stored manually by the user by executing a command. Once the maximum number of lines has been reached according to the memory’s capacity, the D.I.. will start over and #1 and write over the previous data. The operator should consider what the maximum realistic amount of lines needed in a weighing session will be. For example, a perfect 10 minute Bollard Pull test requiring one measurement every 30 seconds, would require only 20 lines. Therefore a D.I.. with a 600 line memory would be sufficient.
Data Logger Operation
A) Storing the load value currently displayed on the screen during system operation:
Press DATA L. DATA L will appear on the screen. Press ENTER. The display will flash OK and then revert back to the current load value. The reading has now been stored in the D.I.. memory
B) Storing a MAX reading in the D.L. memory:
Along with the current load value, the D.I can also record the load value currently stored in the system’s MAX memory.
Press DATA L. DATA.L will appear on the screen. Then press MAX. The display will flash OK and then revert back to the current load value. The current MAX reading has now been stored in the D.I.. memory. Note: MAX readings will appear as DI MAX under the function (FUNCT) column when output to a PC/printer.
C) Seeing the total number of D.L. entries:
Press DATA L. DATA.L will appear on the screen. Then press TARE. The display will read DL. N and then show the total number of readings currently stored in the D.L.. memory.
D) Resetting/clearing the D.L. memory:
Press DATA L. DATA.L will appear on the screen. Then press RESET and RESET will flash before reverting back to the current load value. The D.I. memory is now clear and the next load logged will appear as #1.
E) Downloading the stored info to PC/serial printer:
Note that for a PC, you will need to use a terminal emulator such as Microsoft’s Hyper Terminal™
To output the entire contents of the D.L. memory, press DATA L. When the screen reads DATA.L press PRINT. All readings should now be output to the screen/printer.
Ideally, the D.I data should be output while the handheld indicator is still connected to the load cell. However, the indicator may be used alone to output the readings if need be. When turning the indicator on while not connected to the load cell, wait for the screen to show ESC. Then you may output the data with the commands above.
Automatic Data Logger (if included)
Note: The system must be equipped with the RS-232 digital output and the Real Time Clock.
The automatic data logger (ADL) automatically logs ongoing weight values, repeatedly, in a time interval (1) that is set by the user. It will store up to 600 data lines when using the standard memory, or a higher number of lines when using larger memories. Along with the weight value, a data line includes:
- The unit of measurement (Lbs, Kg, kN etc.)
- The tare condition (gross or net)
- The line number in the memory (1, 2, 3 etc.)
- The date and time that the weight value was recorded
- Function: ADL MX, ADL MN, ADL AV.
If the system includes the ADL, the display will show ADL.OF after the indicator is turned “on”. The ADI. functions in time intervals (1) set by the user and has three functions that affect the weight value stored: MAX, MIN & AVERAGE
MAX: The maximum value registered by the system during each time interval will be logged in the memory. To begin logging, the user must switch from ADL.OF to ADL.MX by pressing DATA L and then ESC. One of the functions (ADL.AV,
ADL.MN or ADL.AV) will be displayed. In order to switch to a different function than that which is displayed, the user must again press DATA L. then ESC until the desired function appears. Once the desired function is chosen, the ADL is ready to log.
To start logging press DATA L. and then TOTAL. Display: ADL. MX
To stop logging press DATA L. and then TOTAL Display: ADL. OF
MIN & AVE: Like MAX but the minimum or average value will be stored.
During Logging
After about 25 seconds the display will show: ADL. MX (OR MN, OR AV) and then after another 25 seconds: LOGS. The number of lines logged can be displayed by pressing DATA L. and then TARE. The display will read DL. N. and then the number of lines logged.
Time Interval (1) selection
Enter into the options menu by following the instructions in section 9.
Scroll to ADLTI by using the arrows keys, then
Press: ENTER
Display: DAY
Press: ENTER
Display: 0000-The two digits on the left will be blinking. Use the arrows keys to select the number of days.
Press: ENTER
Display: OK, then HOUR
Press: ENTER
Display: 0000 – Now the two digits on the right will be blinking. Use the arrow keys to select the number of hours.
This procedure continues, enabling the user to select the time interval (1) by selecting.
Days (up to 31) and/or
Hours (up to 24) and/or Minutes (up to 60) and/or
Seconds (up to 60)
Once the selection is completed, press ESC to exit and return to the options menu.
Multiple Wire Rope Falls Option (if included)
Enter into the options menu by following the instructions in section 9. Scroll to MULTI and press ENTER. This display will show the number of times the load value will be multiplied by (number of rope falls). Use the arrow keys ↑ to change the number (1-20). Press ENTER. The display will flash OK, then the number selected, and will then revert back to the options menu. Select another option or press ESC to exit the options menu.
This function is designed to enable the system to be used when the load cell is connected to a single load suspending cable in a multi-cable suspended loading. An example would be when the load cell is connected to the dead end of a multiple wire rope falls crane. The multi option helps the user by multiplying the measured weight by the number of wire ropes the load is actually suspended by.
The load cell senses one wire rope fall in a crane reeving of four wire rope falls; the system will multiply the sensed load by four and display the result. The system will multiply the sensed load by any number selected by the user to suit the actual reeving arrangement for a given set up. The overload threshold levels also receive the correct values which are the normal threshold levels multiplied by the number of falls.
The set points are also multiplied by the multi number automatically.
Best Practice
When weighing with multiple rope falls, the friction created by the pulleys will have an effect on the displayed load. This friction will always be in opposition to the direction of the load’s movement. When lifting, the displayed value will be that of the load the force of the friction. When lowering, the opposite will be true and the displayed value will be less than the actual load. We recommend that measurements are taken either only while lifting, or only while lowering the load, with the latter being preferred. This will minimize the error in the displayed load.
Dampened Reading aka Averaging (if included)
To switch on the dampening mode, press ZERO + TARE simultaneously. The display will show AVR.ON.
To switch off the dampening mode, press both keys again. The display will show AVR.OF.
When calibrating the system, avoid using dampening, i.e. turn off the dampening mode.
The dampening option is effective mainly in cases where instability in the lifted load is cyclical, such as in a load that swings in the manner of a pendulum. In this case the dampening option can find the real weight in a relatively short amount of time, before the load stops swinging. In fact, if the load is in constant motion, this will be the only practical way to find the load’s true weight.
In cases where the load changes randomly the dampening option is very limited in its performance, especially when high rates of change are involved.
The dampening option calculates the average load based on the measurements taken over a given number of seconds (here called 7). When measuring begins, the first reading will show after about one second. After two seconds, the display will show a reading based on the average of the readings from the first two seconds. After three seconds, the displayed reading will be the average of the first three seconds. This will continue for the first I seconds.
After T seconds and onward, the display will show an updated reading about once per second based on the average of the readings from the previous T seconds. The interval T can only be set in the factory. It is set as standard to 5 seconds but can be set to any number of seconds according to the customer’s request.

Troubleshooting
- The system will not turn on:
a) After the system has been turned off, you must wait a few seconds before turning it on again. Try again after waiting about 10 seconds.
b) Open the battery compartment cover. Check the battery connection and wiring.
c) Remove the batteries and replace them in the holder to improve contact.
Check the battery pack voltage with a voltmeter. The voltage should be above 3.45V. If it is not, replace (disposable) or charge (rechargeable) the batteries.
d) If you cannot check the voltage, try replacing the batteries. - The system will not turn off
Disconnect and reconnect the batteries. Turn the system on and then try turning it off. If it does not switch off, it can still be used until you have an opportunity to send it to an authorized service center. With full batteries, the system will function for more than 3 months (or more than 2 months with rechargeable batteries) if left on continuously. If you leave it turned on but unloaded (0 shown on the display) the system will go into power saving mode and battery usage will be halved. - DANG.R sign displayed when not overloaded:
a) Completely unload the system and press the ZERO key.
b) Turn the system off. After waiting approximately 15 seconds turn it on again.
4. The system freezes and does not react to changes in force or to keyboard commands:
a) Disconnect and reconnect the batteries. If the fault recurs frequently, send the system to a service center. - No load cell No L.C sign:
This means that there is no connection to the load cell.
a) If this occurs when using the extension cable, try it without the cable ie. directly to the short cable attached to the hand held indicator.
b) The system should be checked in an authorized service lab. - The system switches itself off:
a) Check the batteries (see battery care section).
b) Try to operate the system without the extension cable as per #5. If this is the
problem, replace the cable. If the problem persists, send the system to be checked in an authorized service laboratory.
