1. INTRODUCTION and INSTALLATION General and Safety Information Risk of Electrical Shock: Disconnect all power sources before making cable connections to the scale platform or indicator. For use in dry environments only. Do not operate in hazardous areas. Read and understand all operating instructions before using this product. Keep this manual for future reference. Record the weight shortly after placing a load on the platform.

Remove the scale from the packaging and place it on a work table with the feet facing up. Remove the shipping protection screw. See below pictures. 2. Place the scale on a hard, flat, and level surface. 3. Adjust the feet to level the scale. 4.
2. OVERVIEW OF CONTROLS AND FUNCTIONS Indicator Display Character Definitions PS‐103 www.measuretek.net .
Indicator Display >0<- Scale is zeroed and gross weight is 0, tare is 0. Net - Display reading is net weight; tare is not 0. lb, kg, oz - Unit of measure. Hold - Scale is in dynamic weighing mode. - Hold flashes - actual fluctuating weight is displayed. - Hold does not flash - locked weight is displayed.
3. OPERATIONS Normal Weighing Mode 1. Power on the scale by pressing the ZERO/ON/OFF key. 2. When the display stabilizes, but it doesn’t show zero, press ZERO/ON/OFF to set a new zero point. 3. Place objects on the scale platform and read the weight on the indicator. Note: Objects should be placed at the center of the platform. Corner or side loading heavy objects may risk overloading an individual load cell and damage the scale. 4. 5. 6. 7. Yes No To change the weight unit of measure, press the UNIT key.
4. Calibration Note: (1) Before calibrating the scale, you should prepare standard weights (more than 10% of FS weight) for calibration. (2) In the following steps, pressing ZERO/ON/OFF will exit calibration. 1. Move all weight from the scale. Under normal weighing mode, press and hold TARE and ZERO/ON/OFF keys for more than 4s to enter calibration mode. 2. The indicator will show “CAL-?”, which means the scale is ready for calibration. Press the TARE key to confirm and continue into calibration mode. 3.
5. View ADC Code or Power Voltage 1. In normal weighing mode, press and hold HOLD/PRINT and ZERO/ON/OFF keys until “code” is shown, which means the indicator is working under display inner code mode. In this mode, you can examine the stability of the weighing system, the increment value of ADC code corresponding to the loaded weight, and/or power voltage to PCB.
6. Configuration Parameters Setup 1. When the scale is off, press and hold ZERO/ON/OFF and PRINT/HOLD keys until ‘C0NF’ is shown, which indicates that the scale is in Configuration parameter setup mode. 2. During setup mode, press the UNIT key to change the flashed digits, and use the HOLD/PRINT key to shift the flashed position. Press the TARE key to confirm the flashed digits. Press the ZERO/ON/OFF key to exit this mode. 3.

4. More Information for Configuration Parameters: 4.1 The division (d) of scale is determined by C3,C4 and C5 : If C3=3 (interval is 5), C4=2(decimal point is x.xx), C5=1(unit is lb), Then C3xC4xC5=5x0.01xlb=0.05lb, So, d=0.05lb 4.2 The capacity is determined by C1 and d : If C1=3000, d=0.05lb, then C1xd=3000x0.05lb=150.00lb, So, the capacity (FS) is 150.00lb 4.
7. User Parameters Setup In normal weighing mode, press UNIT and ZERO/ON/OFF until “USer” is shown to enter in the user parameters setup mode. 2. During this mode, press the UNIT key to change the flashed digits, press the HOLD/PRINT key to shift the flashed position. Press the TARE key to confirm and save the set data and enter next setting. Press the ZERO/ON/OFF key to exit this mode. 3.
4. More Information for User Parameters Setting: U5 to set serial communication output format: (1). U5=0: No serial communication function. It will not transmit or receive any data even if the scale is installed with serial communication hardware. Serial communication function can be only activated when the scale is in normal weighing mode. (2). U5=1: Press PRINT key, the scale will output the current stable weight, weight unit, and current Status data ; it does not receive any data .
c) d) weight data is filled by ‘_’). (3). If the zero point has an error, it will return ten ‘_’ characters. (4). The character will be ‘-’ for negative weight or a space character for positive weight. Minus sign follow after the first digit. (5). Useless leading zero before digits are suppressed.
(6). Command: L (4ch 0dh) Response: H1H2H3 If HOLD function is enabled, go to or exit from HOLD mode, similar to pressing the HOLD key. (7). Command: X (58h 0dh) Response: NONE Power off the scale, similar to pressing and holding the ZERO/ON/OFF key for 4 seconds. (8). Command: all others Response: ? Unrecognized command e) f) Additional Commands and Responses for Scale Base Application: (1).
