Potentiometer Adjustment Instructions


Users can tell us the field application parameters before ordering the product, so that it can be adjusted and sealed according to the technical requirements at the factory. 

As shown in the figure: four multi-turn potentiometer knobs on the side of the shell, clockwise rotation adjustment decreases, counterclockwise for increasing. 

Zero calibration adjustment: given the minimum input signal, adjust the potentiometer knob to make the output current zero. 

Fullness calibration adjustment: Given the maximum input signal, adjust the potentiometer knob to maximize the output current. 

Rising Edge Response Time: Connect the oscilloscope to both ends of the output load, adjust the potentiometer and observe the rising edge time of the waveform. 

Falling edge response time: connect the oscilloscope to both ends of the output load, adjust the potentiometer and observe the falling edge time of the waveform.


Typical Application Examples 

Application 1: Direct input of sensor-transmitter signals such as 0-10V/PWM/0-10K/Pt100/0~1Vrms/RMS. 

In this application mode, the signal input, signal output and auxiliary power supply are 3000VDC triple isolated.

Application 2: Application mode in which the module's own distribution output of 10VDC is used with an external resistor or potentiometer to form an electronic ruler or bridge input. 

In this application mode, the ground (GND) of the signal input and the ground (GND1) of the power distribution output are connected to a common ground. Therefore, the signal input and signal output are 3000VDC isolated from each other.
