Refresh rate of the display: ........ 10 times/second approximately. Input voltage range: ................... -1 mV ~ +15 mV.
3. Installation and Precautions 3.1.1. Installation and Precautions The weighing indicator is a precision electronic instrument. Handle it carefully. The operating temperature is -10°C to +40°C (14°F to 104°F). Do not install the scale in direct sunlight. Mis-operation or other problems may be caused by an unstable power source including momentary power failure or instantaneous noise. Use a stable power source. Do not connect the power cord before the installation has been completed.
3.1.3. Caution Adjustment of the Load Cell Output Use a metal film resistor in the range of 50kohm to 500kohm with a good temperature coefficient, when adding a resistor to adjust a load cell output. Use as large of a resistance value as possible in the range in which the zero adjustment is possible. Solder this resistor at a point near the load cell or the indicator. In Case of Reducing the Output Voltage When the zero output is too large, add a resistor between EXC+ and SIG-.
3.1.5. Installing an Option board Caution Do not remove any screws without the following step. This is the procedure for the data output board (OP-03, OP-05, OP-07 and OP-08). Step 1 Remove the power cord from the AC power source. Step 2 Remove eight hex bolts (one of them is the sealing bolt) from the rear panel.
