SAFETY PRECAUTIONS
For safe operation of the weighing indicator, please follow these instructions: Calibration inspection and maintenance of the indicator are prohibited by non-pro-
fessional staff Please ensure that the indicator rests on a stable surface The indicator is a piece of static sensitive equipment; Please cut off power during
electrical connections Touching the internal components by hand is prohibited DO NOT exceed the rated load limit of the unit DO NOT step on the unit DO NOT jump on the scale DO NOT use this product if any of the components are cracked DO NOT use for purposes other then weight taking To avoid damaging the battery do not keep charger plugged in once battery is fully
charged Make sure the weight is not over the Max capacity as it could damage the load cell
inside Material that has a static electric charge could influence the weighing. Discharge
the static electricity of the samples, if possible. Another solution to the problem is to wipe both sides of the pan and the top of the case with an anti-static agent
Please take anti-static prevention measures Any accumulated charge on the body of the human operator should be discharged first before opening the protective container with ESDS devices inside. The discharge can be accomplished by: Putting a hand on a grounded surface or, ideally, by wearing a grounded Anti-static
Wrist Strap and an Anti-static Mat
PREPARATION & SET UP
Plug into a wall outlet to avoid interference with other wirings Turn on the indicator while there is no load Calibration may be required before weighing when the scale is initially installed or
moved from a location

OPERATING INSTRUCTIONS
Power On
Turn on the power by pressing the ON/OFF button for 2 seconds. Once on, the scale will flash the voltage and then begin to auto-check and count down from 0-9 sequentially before entering the weighing mode Note: Anything on the scale before powering on will automatically be tared out.
Zeroing
The zero function is used only when the scale is empty and is not at zero due to
material build up Pressing the ZERO key while the scale is stable will reset your scale to 0 Depending on what your manual zero range parameter is set to, you can zero out
any weight within your set selection, after that you will receive an error and will
need to tare out the weight
Unit Selection
To switch between measuring units (kg/lb) press the UNITS key
Tare Function
To Tare: When in gross mode, press TARE to enter net mode and tare out the weight
TARE
The Tare function is used when you only wish to see the current change in weight,
not the entire amount of weight that is on the scale When the indicator is in gross mode (gross light is shown) pressing the TARE key
will Tare the current weight on the scale and enter the net mode (net light shown)
For example if you are using a container add the container to the scale, press tare
and the display will show the tare symbol
and reset back to 0
Add your product to the scale to weigh without the weight of the container
To exit Tare mode press the TARE key again to enter gross mode and you will see
the total weight of the container and the product Note: If you remove the container the scale will show the minus weight of the container
To use a pre-set tare weight
Press and hold the TARE key and SET key at the same time Input the weight you want tared on the keypad Press TARE key to confirm Press TARE to reset back to 0
6
Accumulation
The accumulated function is used to add multiple weights and total them together You can add up to 999 different weights together In weighing mode load the first weight, once stable press the TOTAL key to enter
the accumulated mode. The "total" light will display
TOTAL
Remove the first weight and add the second weight to the scale Once stable press TOTAL key to add the weight to the accumulated total
TOTAL
Repeat previous steps until all desired weights have been added to the total (max 999
times) When you are done and want to display the accumulated total, press the TOTAL and
SET key together. The accumulated number "n###" (the number of weights you
are adding together) will flash on the display followed by the total
TOTAL + SET
If you want to print the accumulated total, hold the PRINT key for one second To exit accumulated mode, press the ESC key To delete the saved weights press the DEL key followed by the set key to confirm
DEL
SET
Repete this process to cleaer all saved weights
Print
If the indicator is connected to a printer and the weight on the scale is stable press the PRINT key to print the current weight
Note: In tare mode the printer can not print if negative weight is shown
7
Counting Function
The counting function is used to count a high volume of identical parts. You can do
this by setting a sample and then either adding to the sample or taking away from
the sample to count the number of objects on the scale In weighing mode: press COUNT to enter count mode COUNT Then press COUNT and SET at the same time to set your sample with the keypad
COUNT + SET
(ex. If you are counting pencils, you would add a sample of pencils to the scale, if
you add 50 pencils to the scale you would enter 50 on the keypad.)
# Press
on the keypad to set your sample
The scale is now ready to start counting, load your product on the scale and the
indicator will show the quantity
+ 450 pencils
(ex. if you add 450 pencils to your sample of 50, the scale will read 500 pencils) To see the weight on the scale press COUNT To exit counting mode press the ESC key If you want to count a different product hold the COUNT and SET keys together to
enter a new sample
Hold
There are 4 different hold functions you can choose from in the C11 parameter
1. Peak Hold: Grabs the highest weight (for materials testing, ie. tension and pulling force) Press the HOLD key then add weight to the scale The indicator will show the highest weight it recorded and hold it on the screen until
a higher weight is placed on the scale 2. Manual Hold: Grabs the current weight and holds it so it will not change/fluctuate While weighing, press HOLD and the indicator will hold the current weight on the
screen until HOLD is pressed again 3. Auto Hold: If the weight on the scale is above 20d (20 x division) and is stable, the indicator will hold that weight on the screen for 3 seconds then go back to general weighing Pressing the hold key is unnecessary, holding is done automatically when the scale
is stable 4. Average Hold: Used for animal weighing, the indicator will display the average weight sampled from 3 seconds

Recipes
Recipes allows you to store formulas for different products you may continuously be weighing, and creates a quick easy way to streamline your weighing.
For example: If you are selling 2 lb bags of cherries, you would create a recipe by setting a tolerance using upper and lower limits. This tolerance allows you to quickly separate multiple 2 lb bags of cherries. For this example we are going to use a tolerance of 0.1 lbs. Meaning we would set our upper limit to 2.10 lbs and our lower limit as 1.90 lbs. We are telling the scale, that any weight taken out of the container between 1.9 lbs - 2.1 lbs is acceptable, anything higher or lower is not. Now that our recipe is set add your large container of cherries on the scale. Then tare out your container of cherries, setting the scale to 0. Now if you start scooping out cherries from the container into a bag, the scale will read in negative (ex. -1.5 lbs) until the amount set in our recipe is reached. When you have taken out ~2 lbs (what your tolerance is set to) the scale will reset back to 0. Then the process can be repeated again, take out ~2 lbs of cherries until the scale reads 0.
To set these formulas: 1. Press SET, the screen will show what recipe number you are on, the default is 1. If it
is not on 1, use the keypad to enter the recipe number you would like to set. (up to 99 recipes can be saved) 2. Press # to confirm that number 3. You will now be back in weighing mode the screen will show 0 4. Press SET and ESC at the same time to enter the settings mode 5. use the keypad to input 13 followed by # to confirm 6. Use the keypad to enter your Upper Limit, followed by # to confirm (ex. 2.10) 7. The screen will show C14, press # to enter this setting 8. Use the keypad to enter your Lower Limit, followed by the # key to confirm (ex. 1.90) 9. The screen will show C15, press ESC to save and return to weighing mode 10. Then place your container on the scale, The screen will show you the total weight 11. Press TARE to set the scale back to 0 12. After pressing tare you are able to remove product from the scale until you are within your set tolerance and the scale reads 0. (ex. 1.9 - 2.1 lbs)
To use already set formulas: 1. In weighing mode, press SET, followed by the number the recipe is saved under 2. Press # to confirm 3. Add your product to the scale, Then press TARE 4. You can now start removing product and the scale will read 0 when its within the set
tolerance 5. To change recipes, press SET followed by the number the recipe is saved under

HELPFUL DEFINITIONS
Division: The amount of increments a scale offers. How accurate the scale can be
Capacity: the maximum amount the scale can contain
Initial Zero Range: The percentage of weight allowed on the scale when indicator is powered on that will automatically zero. example: If initial zero range is set to 10% of the max. capacity and your max. capacity is 100lbs, you can place up to 10lbs of weight on the scale and when the indicator is powered on, it will automatically zero out the weight.
Manual Zero Range: The percentage of weight allowed on the scale where the indicator will let you manually zero (anything above this percent will be tared)
Zero Tracking Range: A subset to the manual zero range; if the weight on the scale is not stable, the zero tracking range still allows you to zero within a set division of the scale
Zero Tracking Time: A subset to the zero tracking range, it is the time allowed for the scale to fall within the zero tracking range tolerance and still qualify to be zero'd
Overload Range: Weight allowance that is out of the set calibrated range. Adds a tolerance to the calibrated max. capacity without having to recalibrate. example: If your scale has a max. capacity of 1000lbs with a division of 1 and you set the overload range to 60, you can add 1060lbs of weight to the scale without it displaying an error code
Negative Display: How far you can go in the negative direction before displaying an error code
Standstill Time: How fast the scale will stabilize
Standstill Range: How much the scale can fluctuate before being determined stable
Digital Filter: For filtering moving weight, such as animals, It changes how sensitive the scale is to variations in movement.
Noise Filter: A filter for how susceptible the scale is to general variations
Baud Rate: The rate at which information is transferred in a communication channel. example: In the serial port context, "9600 baud" means that the serial port is capable of transferring a maximum of 9600 bits per second.

TROUBLESHOOTING
Error Codes
Error
UUUUUU
Reason 1. Overload 2. Wrong connection with load cell 3. Load cell has quality problem
1. Calibration is no good
nnnnnnn 2. Wrong connection with load cell 3. Load cell has quality problem
ERR1 ERR2
During calibration, weight is not used or the weight is above the max. capacity
During calibration, the weight is below the minimum required weight
ERR3
During calibration, the input signal is negative
ERR4 ERR5 ERR6 ERR9 ERR10
During calibration signal is unstable EEPROM Error Exceed Zero Range The number to chick is too big No information
Solution 1. Reduce the weight 2. Check load cell connection 3. Inspect load cell; Check the input/output 4. See Q&A section 1. Make sure scale is level 2. Check load cell connection 3. Check load cell input and output resistance 4. See Q&A section Use correct weight within the defined range
The calibration weight minimum is 10% of the max. capacity set in C04. Recommended to use 60%-80% of max. capacity if possible 1. Check all wire connections 2. Check load cell 3. Recalibrate 4. PCB replacement needed if steps 1-3 fail After the platform is stable, start calibration
Change PCB
Remove the load and See Q&A section
Input again with proper number
The accumulation is empty

Q&A
Q: The scale does not turn on
A: Make sure the power cord is plugged in, and that there is power. One easy way to test this is by connecting another appliance to the same outlet and see if it's
operational Q: The reading goes negative when a load is applied A: Try interchanging the Sig+ and Sig- wiring connected to the load cell and/or
junction box (if one is used) Q: How do I resolve ERR6 error?
A: Please follow the procedure below: 1) Turn on the indicator and make sure nothing is on the scale, and that the scale
is level and not wobbling 2) Press and hold the "PRINT and HOLD" key simultaneously for a few of seconds 3) The screen will read "C01" 4) Using the arrow keys, change C01 to C20. You have to change the 1st digit from 0 to 2 first before you can change the 2nd digit 1 to a 0. 5) Press "PRINT" key to enter C20 parameter 6) Change the value of C20 on the right to 100 if possible using the up arrow key. If 100 is not available change to 20 7) Press "PRINT" key to enter your selection 8) The screen will read "C21" now 9) Press "PRINT" key to enter C21 parameter 10) Change the value on the right of C21 to 100 if available, 20 if not 11) Press "PRINT" key to enter your selection 12) he screen will read "C22" now 13) Press "TOTAL" key to save and exit 14) Power the indicator off and then on, and see if this resolves the ERR 6 issue. If not, then following the Q&A answers below for resolving "nnnnnn"and "uuuuuu"
errors Q: How do I resolve "nnnnnn" and "uuuuuu" error? A: 1) Check to see if the cable that runs from the indicator to the junction box is
damaged. If it is, replace the cable. 2) Open up the junction box (if available) and check to see if there is any water damage. If so, replace the junction box 3) Make sure all the wires on all 5 terminal blocks (5 wires on each terminal block)
are not loose. Re-tighten the screws even if the wires seem to be connected 4) Recalibrate 5) If steps 1-4 do not work, there is a possibility one or more load cells are defective (consult with tech@selletonscales.com for further instructions)
