ae ADAM ACBplus Series User Manual

The scales can be operated with an A.C. adapter or using an internal rechargeable battery.
The weighing process is fast and accurate, making it suitable for the general purpose weighing applications, parts counting, percentage weighing functions, etc.

There are 7 models in this series with capacities ranging from 150 grams to 3 kilograms.
All models include automatic zero tracking, automatic tare, accumulation facility that allows the weight to be stored and recalled as an accumulated total and bi-directional RS-232 interface for communicating with a PC or printer.

All have stainless steel weighing platforms on an ABS plastic base assembly.
Keypads are sealed with colour coded membrane switches.

The scales have an optional weigh below facility.
The displays are large, easy to read liquid crystal type displays (LCD). It is provided with a backlight and also a bar-graph at the bottom to display the weight of the item on the pan with respect to the capacity of the scale.

The LCD normally shows the weight and the units of the weight selected previously (Grams, Carats, Pounds, etc). See section 5.1 for details on Units.

INSTALLATION

LOCATING THE SCALE

Avoid extreme temperatures. Do not place the scale in direct sunlight or near air conditioning vents. Avoid air movement such as from fans or opening of doors and windows.
Avoid unsuitable tables. The table or floor must be rigid and not vibrate. Do not place near vibrating machinery.

Avoid unstable power sources. Do not use the scale near any large user of electricity such as welding equipment or large motors.
Avoid high humidity that might cause condensation. Avoid direct contact with water. Do not spray or immerse the scales in water.

Keep the weighing area clean.
Do not stack material on the scale when not in use.

Protect the scale from extreme temperatures, vibration and dust.

SETTING UP THE SCALE

Remove the Shipping Protection screw from the bottom of the base.
The scale comes with a stainless steel platform, packed separately.

Place the platform in the receptacles on the top cover.
Do not press with excessive force- it could damage the load cell inside.

Level the scale by adjusting the four feet. The scale should be adjusted such that the bubble in the spirit level is in the centre of the level and the scale is supported by all four feet.
Turn the power on by pressing the [On/Off] switch.

The unit will display the model number and the software revision number for a while and then will count down performing a self-test.
When ready the display will show zero along with the weighing unit selected during the last operation.

BATTERY CHARGING

The scales can be operated from the internal rechargeable battery or using an A.C. Adapter. The battery life is approximately 24 hours depending on the usage of the backlight.
The display will show an indication when the battery needs to be charged. To charge the battery, plug in the AC adapter at the back of the scale and attach it to the main power supply. The charging indicator at the left top corner of the LCD will be on.

DISPLAY

KEY DESCRIPTIONS

KEYS	PRIMARY FUNCTION	SECONDARY FUNCTION
[On/Off]	To turn the scale On or Off.	—–
[Zero]	Sets the zero point for all subsequent weighing. The display shows zero.	A secondary function is of “Enter” key for setting parameters or other functions.
[Tare]	Tares the scale. Stores the current weight in memory as a tare value, subtracts the tare value from the weight and shows the results. This is the net weight.	Pressing [Tare] again will cancel the tare value.
[%]	Enters the percent weighing function.	When in percentage mode, press [%] key to return to normal weighing mode.
[Smpl]	Use this key to enter counting mode from the normal weighing mode,	A secondary function allows the user to return to normal weighing mode while in counting mode. It also clears the accumulated value from the memory when pressed during recalling the total.
[Mode]	Pressing this key will cycle through the weighing units which are enabled. It also scrolls through the options during setting up a parameter.	Displays the unit weight, total weight and the count when in the parts counting mode.
[Print]	To print the results to a PC or printer using RS-232 (A USB interface will be available shortly). It also adds the value to the accumulated memory if the accumulation function is not automatic.	Secondary function is to return to normal operation when the scale is in a parameter setting mode.

OPERATION

ZEROING THE DISPLAY

Press the [Zero] key when the platform is empty.
[Zero] key may be pressed at any time to set the zero point from which all other weighing and counting is measured.
When the zero point is obtained the “O” indicator will be on in the left bottom corner of the LCD.
The scale has an automatic re-zeroing function to account for minor drifting or accumulation of material on the platform. However you may need to press the [Zero] key to re-zero the scale if small amounts of weight are shown when the platform is empty.

TARING

Zero the scale by pressing the [Zero] key, if necessary.
The “O” indicator will be on.
Place a container on the platform, a value for its weight will be displayed.
Press the [Tare] key to tare the scale. The weight that was displayed is stored as the tare value. It is subtracted from the displayed value, leaving zero on the display. The NET symbol will be on at the right top corner to indicate that the weight displayed is the net weight.
As the product is added, only the net weight will be shown.

The scale could be tared a second time if another type of product was to be added to the first one. Again only the weight that is added after taring will be displayed.
When the container is removed a negative value will be shown. If the scale was tared just before removing the container, this value is the gross weight of the container plus all products those were removed.
The “O” indicator will also be on because the platform is back to the same condition as it was when the [Zero] key was last pressed.

To cancel the tare value, press [Tare] again.

WEIGHING

After zeroing the display and taring the container, place the sample in the container to determine the weight of the sample. The weight will also be displayed through a bar-graph at the bottom of the LCD.

The display will show the weight and the units of weight currently in use. The stable indicator will be on. To change the weighing units, press [Mode] to cycle through the options of units those are enabled. See the Parameter section to enable or disable the weighing units.
The accumulated value in the memory will be cleared when a new weighing unit or during recalling the memory, %weighing or parts counting is selected.

PERCENT WEIGHING

The scale will allow a sample weight to be shown as 100%. Then any other weight placed on the scale will be displayed as a percentage of the original sample.
For example is 350g is placed on the scale and the [%] key is pressed the display will show 100.00%. Removing the 350g weight and place a 300g weight on the scale. The display will show 85.71% as 300g is 85.71% of 350g.
Note: The scale may jump by large numbers unexpectedly if small weights are used to set the 100% level. For example, if only 23.5g is on a scale with 0.5g increments and the scale is set to 100%, the display will show 100.00%. However, a small change of weight will cause the display to jump to 102.13%, as one scale division (0.5g) increase to 24.0g will be equivalent to a 2.13% increase.

Pressing the [%] key again will return the scale to normal weighing.

PARTS COUNTING

When the scale is in normal weighing mode, pressing the [Smpl] key will start the parts counting function.

Before beginning, tare the weight of any container that will be used, leaving the empty container on the scale.
Place the number of samples on the scale. The number should match the options for parts counting, 10, 20, 50, 100 or 200 pieces.
Press the [Smpl] key.

The scale will initially show “SP 10” asking for a sample size of 10 parts. Press [Mode] to cycle through the options: 10, 20, 50, 100, 200 and back to 10.
Press [Smpl] again when the number matches the number of parts used for the sample. As more weight is added the display will show the number of parts (PCS) with respect to the chosen sample size.
Press [Mode] to display unit weight (W/P), total weight (g) or the count (PCS). The total and the unit weight are shown in the current units.

Press [Smpl] to return to normal weighing.

ACCUMULATION

When the scale is set for automatic accumulation, the weight will be added to the memory when the scale becomes stable. The scale must return to zero before another weight is added.

When the scale is set to manual accumulation (See the Parameter Section) the weight displayed will be stored in memory when the [Print] key is pressed and the weight is stable.
The display will show “ACC 1” followed by the total value in the memory for 2 seconds before returning to displaying the weight of the item on the scale.
The weight will be output to a printer or PC.

Remove the weight, allowing the scale to return to zero and put a second weight on.
Press [Print], the display will show “ACC 2” followed by the new total in the memory for 2 seconds before returning to displaying the weight of the item on the scale.
Continue until all weights have been added.

To view the totals in memory press the [Print] key when the scale is at zero. The display will show “ACC xx” (where “xx” is the total number of readings) and the total weight, before returning to zero.
The total will also be printed via the RS-232 interface.
To clear the memory, press [Smpl] immediately after pressing [Print].

PARAMETERS

The scale has 5 parameters that can be chosen by the user to set the scale.
To set the parameters press the [Mode] key during self-checking test.
After a few seconds, the display will show the first function “F1 UNT”.

To view the current settings of each parameter, press the [Zero] key.
Press the [Zero] key again to cycle through the other parameters along with their current settings. For example, if “oFF” is displayed with the weighing unit Pounds, the user will not be able to use this unit while weighing a sample.
Press [Mode] to change the settings of a particular parameter. For example, to enable the weighing unit pounds change the setting to “on” by pressing [Mode] now.
