Electronic scales are precision instruments. Do not operate near cell phones, radios, computers or other electronic devices that emit radio frequencies that may cause unstable readings. Avoid using in heavy vibration or heavy airflow conditions. Specifications Model MVS1 Series 77lb (35kg) 165lb (75kg) 440lb (200kg) Max Capacity 0.05lb (0.02kg)
Contents Indicator & Scale Platform Outer Hexagonal Wrench DC9V 600mA UL Adapter Owner’s Manual Installation 1. 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.
Indicator Display ZERO- 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.
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.
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.
5. View ADC Code or Power Voltage 1. In normal weighing mode, press and hold HOLD/PRINT and ZERO/ON/OFF keys until “ ” 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.

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 4.3 Operation on C16 :...
7. User Parameters Setup 1. In normal weighing mode, press UNIT and ZERO/ON/OFF until “ ” is shown to enter in USer the mode. 2. In this mode, press the UNIT key to change the flashed digits, press the HOLD/PRINT key to shift the flashed position.

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.

“lb” and one for a space (<sp>) after lb. Units of measure abbreviations are always lower case. (1). If the weight is overcapacity, the scale will return ten ‘^’ characters (the field of minus sign, decimal point, weight data is filled by ‘^’). (2).
