Adjustable Voltage Current Analog Simulator 0~20mA Signal Generator DC 0~10V Adjustable Voltage Current Analog Simulator 0~20mA Signal Generator for Signal Sources/Valve Adjustment/Inverter Control/PLC, etc. Function: Rotate a multi-turn precision potentiometer to generate 0/4 - 20mA current signals and 0-10V voltage signals. Use as a signal generator, for valve adjustment, inverter control, PLC debugging, panel debugging, LED testing, and simulating transmitter output. Product Parameters: Working Voltage: DC24V Input Signal: Potentiometer Output Signal: 0/4 ~20mA or 0 ~10V Display Accuracy: Current: 0.1mA; Voltage: 0.01V Dimensions: 100*68*38mm / 3.94*2.68*1.50" Debugging Procedures: A. Current Display Calibration: Turn the multi-turn potentiometer clockwise to maximum, switch the display switch to the right, and use a multimeter to test the actual output current. Adjust the current display adjustment potentiometer to match the displayed value with the actual output value. B. Voltage Display Calibration: Turn the multi-turn potentiometer clockwise to maximum, switch the display switch to the left, and use a multimeter to test the actual output voltage. Adjust the voltage display adjustment potentiometer to match the displayed value with the actual output value. Package Includes: 1 x Signal Generator
