By turning a precision multi-turn potentiometer, this unit generates configurable current and voltage signals: 0-20 mA, 4-20 mA, and 0-10 V. 0-20mA/4-20mA/0-10V Signal Generator Key benefits - Simple, reliable manual signal source for calibration, testing, and setup without software. - Provides precise adjustment of current and voltage signals for compatible automation and instrumentation tasks. - Flexible for multiple applications with common signal ranges used in industry. Core attributes - Function: generates 0-20 mA or 4-20 mA current signals and 0-10 V voltage signals via a precision multi-turn potentiometer. - Compatibility: suitable for signal source generation, valve adjustment, inverter control, PLC debugging, instrument testing, LED testing, and analog transmitter output. - Performance: manual adjustment allows fine calibration of output to match system requirements. Use scenarios - Calibrating PLC analog inputs and control loops in automation projects. - Setting valve actuators or inverter control signals during commissioning. - Testing instrumentation, analog transmitters, and LED test setups in bench environments. Debugging steps: A) Current Display Correction - Rotate the multi-turn potentiometer clockwise to the maximum position. - Pull the display switch to the right. - Measure the actual current with a multimeter set to current. - Adjust the potentiometer until the display value matches the measured current.
