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 housing, turn clockwise to adjust the decrease, counterclockwise for the increase.
Zero calibration adjustment: Given the minimum input signal, adjust the potentiometer knob so that the output current is zero.
Fullness calibration adjustment: Given the maximum input signal, adjust the potentiometer knob so that the output current is the maximum value.
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: Apply the module's own distribution output of 10VDC, and external resistors or potentiometers to form an electronic ruler or bridge input application mode。
In this application mode, the ground of the signal input (GND) and the ground of the distribution output (GND1) are connected to a common ground. Therefore, the signal input and signal output are 3000VDC isolated from each other.
