1. By Rotating A Precision Potentiometer Multiple Turns, A 0/4-20mA Current Signal And A 0-10V Voltage Signal Can Be Generated. 2. This Signal Can Be Used For Signal Source Generation, Valve Adjustment, Inverter Control, Plc Debugging, Instrument Testing, Led Testing, And Analog Transmitter Output. 3. 0-20mA/4-20mA/0-10V Signal Generator 4. Debugging Steps: A: Current Display Correction: Adjust The Multi-Turn Potentiometer Clockwise To The Maximum Position, Pull The Display Switch To The Right, Use The Current Setting Of The Multimeter To Test The Actual Value Of The Current Output, And Adjust The Current Display To Adjust The Potentiometer. Make The Display Consistent With The Actual Current Output Value. 5. B: Voltage Display Correction: Adjust The Multi-Turn Potentiometer Clockwise To The Maximum Position, Pull The Display Switch To The Left, And Use The Voltage Range Of The Multimeter To Test The Actual Value Of The Voltage Output. At This Time, Adjust The Voltage Display And Adjust The Potentiometer To Make The Display Consistent With The Voltage Display. The Actual Voltage Output Value Is Consistent. Working Voltage:DC 24V Input Signal:Potentiometer Output Signal:0/4-20mA Or 0-10V Display Accuracy:Current 0.1mA, Voltage 0.01V Note: Different Batches May Have Differences In Product Appearance, Color, And Printed Characters, Which Will Not Affect The Use Need to be connected to a charger and charging cable to use (charger and charging cable not included) Colour:As Shown Material:ABS Size:About 100mm (Length) x 68mm (Width) x 38mm (Height) Package Contents: 1 * Signal Generator Only the above package content, other products are not included.
