1.0 TECHNICAL DATA The ACB series of precision electronic scales offers a range of capacities from 150 grams to 3 kilograms. The ACB series now includes 2 models with high resolution,1:60,000. These are the ACB-600H and ACB-1200H. The balances are very simple to use and are applicable for general weighing. The user can also use the parts counting and percent weighing functions for special applications. Special functions are available for weighing in up to 13 different units of weight. The standard RS-232 interface allows the weight to be sent to a computer or printer. The baud rate is adjustable from 1200 to 9600 baud.
1.1. INSTALLING THE BALANCE ♦ Unpack the balance carefully. ♦ Place the scale on a stable surface. The weighing area should be kept clean and dry. Do not install the balance near extremes of heat and cold. Protect the balance from vibration, dust and air draughts. ♦ Place the pan onto the pan support gently, being careful not to press on the pan. ♦ Remove the shipping protection from the side of the balance. Retain this part so that if the balance is to be shipped again it can be inserted to protect the load cell. (See below). ♦ Turn the adjustable feet until the balance is level (check the bubble level on the front of the scale). ♦ Insert the power supply connector in the plug on the rear of balance. Plug the power supply into the mains supply. ♦ Press the ON/OFF key to activate the balance. ♦ Wait until the balance AutoTest is finished and a stable zero is displayed.

Secondary Function
2.0 OPERATION Press the ON/OFF key for power on, the scale will be on the weighing mode using the initial units of weight selected. See Function Set-up. Press MODE key to choose the weighing, counting or percentage (%) functions.
2.1
WEIGHING MODE
Units selection Press the UNITS key to choose the weighing units and the display will be changed to the new value with the units shown. There are up to 13 units of weight that can be enabled. See Parameter Set-up Section. Tare Function Tare weight is the weight of a container and can be subtracted by placing an empty container on the scale. When the display is stable, press the TARE key. The display will become zero and the display will have a tare indication. Cancel the tare function by pressing the TARE key with no weight on the scale. Tare range is the full capacity of the scale. Zero Function If the zero shifts during operation, press the ZERO key to set it to zero. The Zero function is only active over a +-2%. Range. After setting to zero, the scale capacity will go to the maximum value.
2.2
COUNTING MODE
The scale will count parts by weighing a preset number of samples and setting the display to show the number. Then, as more samples are added, the display will increase. If necessary, place a container on the scale and press TARE before beginning.

Sampling a. After selecting parts counting with the MODE key, press the UNITS key to select the sample size (10, 20, 50, 100 pcs) b. Put the sample number (same as selected in step a) on the scale and press PCS key. When the symbol “C” disappears the sampling procedure is finished and you can start to use the counting function. c. If the unit weight is too small (less than 0.2 of a scale division), the display will show: --or-- PCS. It would be best to use larger parts or to use ten times as many parts as required and reduce the displayed values to 1/10th.
2.3
PERCENTAGE % MODE
Sampling a. After selecting % Weighing with the MODE key press the UNITS key to choose either 100.0%, 100.00%. b. Put the item to be considered 100% onto the pan and press the PCS key. During the sampling, the % symbol will be flashing and when the sampling procedure is finished, the % symbol will be stable. When the unit weight is smaller then 0.2d, the display will show - - or - -%. Remarks 1. When you finish the procedures of selecting the sample size in the counting mode or percentage (%) mode, press the ENTER key to change back to the weighing mode. Press the PCS key to return to counting or percentage mode. The scale will memorise the previous data automatically so that you can continue to count parts or weigh in percentage. 2. The memory of sampling size data will be cleared automatically every time the MODE key is used to select parts counting or percent weighing.

3.0 BACKLIGHT FUNCTION a. Press the LIGHT key. The display will show “bl.1 " which means “Auto backlight” mode. When the weight is over 10 scale divisions or any of the keys are pressed, the backlight will be effective. When the weight is zero for about 8 seconds, the backlight will go off automatically. b. Press the LIGHT key again. The display will show “bl.2” which means the backlight will always be on. c. Press the LIGHT key once. The display will show “bl.3” which means the backlight will be turned off.
4.0 AUTO CALIBRATION Press the ENTER key for about 3 seconds. The display will show the “Calibration Weight Value”. Put the same weight on the platform. When the display is stable the scale will calibrate. Verify the calibration by removing the mass and checking it again. In some situations the calibration may not be possible and an error message will be shown. In this case simply remove the weight and press the zero button to clear the error. Then try recalibrating again.
5.0 ERROR MESSAGE During self test the scale verifies operation and the load cell. Error messages are: “ E2” A/D counts are too high for zero “- - - - - -“ Scale is below zero “- - OL- -“ Scale is overloaded These messages may also be shown if the load cell protection is not removed, the pan is not installed correctly or the environment is not suitable. Contact Adam Equipment or your dealer for assistance.

6.0 POWER SUPPLY Your scale is delivered complete with a mains power supply. However the ACB scales can be operated from batteries if desired. The scale will not charge batteries and only alkaline dry cells should be used. If batteries are not used for an extended period of time they should be removed from the scale. Do not use the power supply at the same time as batteries are installed. Remove the batteries first. Power supplies: 1. 9V/300mA AC/DC adapter 2. 4 pcs “C” size dry cell batteries Batteries may not have a long life due to the power consumption required by the scale. Typical power consumption is: 1. Standby mode : 0.7mA 2. During operating (no backlight): about 40mA 3. During operating (with backlight) : 90 – 100mA Low Battery: When the battery symbol appears in the right corner of the display, the dry cell batteries need changing.
