By rotating a multi-cycle precise potentiometer, this product can generate 0/4 - 20mA current signal and 0-10V voltage signal, which can used as signal generator, valve adjustment, inverter control, PLC debugging, panel debugging, LED testing, simulating the output of transmitter. Product Parameters: Working voltage: DC24V Input signal: Potentiometer Output signal: 0/4-20mA or 0-10V Display accuracy: Current: 0.1mA; Voltage: 0.01V Dimension: 100*68*38mm Debugging Procedures: A. Current display calibration Clockwise rotating the multi-cycle potentiometer to the maximum, switching the display switch to the right and then using a multimeter to test the actual value of the output current. At this time, you can adjust the current display adjusting potentiometer to make the display value equal to the actual output value. B. Voltage display calibration Clockwise rotating the multi-cycle potentiometer to the maximum, switching the display switch to the left and then using a multimeter to test the actual value of the output voltage. At this time, you can adjust the voltage display adjusting potentiometer to make the display value equal to the actual output value.
