Product : By rotating a multi-cycle meticulous potentiometer, this product can generate 0/4 - 20mA incumbent 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 : Working voltage : DC24V Input signal : Potentiometer Output signal : 0/4-20 mA or 0-10V Display accuracy : incumbent : 0.1 mA ; Voltage : 0.01 V Dimension : 100 * 68 * 38 mm Debugging Procedures : A. incumbent display calibration dextrorotary rotating the multi-cycle potentiometer to the maximum, switching the display switch to the right and then using a multimeter to test the very value of the output incumbent. At this time, you can the incumbent display adjusting potentiometer to make the display value half-and-half to the very output value. B. Voltage calibration dextrorotary rotating the multi-cycle potentiometer to the maximum, switching the display switch to the left and then using a multimeter to test the very value of the output voltage. At this time, you can the voltage display adjusting potentiometer to make the display value half-and-half to the very output value. Package : 1 * Signal Generator .
