Feature:
Calibration:
The packaged product is under calibration. If you need to recalibrate, follow the instruction below to set the Zero and Full Scale.
Zero calibration potentiometer 0V and adjust the control voltage to obtain 4mA output current
1 - Zero Calibration. With the adhesive you can solve the potentiometer knob.
Set the full scale voltage potentiometer (2.5 V, 3.3 V, 5 V, 10 V for example) to adjust the control voltage and adjust the full scale calibration potentiometer to get the output current
2 - Full Scale calibration. The current output will be brighter during the indicator lamp setting. You can use the potentiometer knob to solve the knob.
3 - Calibration Then, if you find that the control voltage is 0V but the output current is not 4mA, you have to repeat the calibration process.
