Features • AMP and Volt Dual Signal: Generate both current and voltage signals effortlessly with a single module, using an easy-to-operate multi-cycle potentiometer • Clear LED Display: Monitor output with confidence using the bright 4-digit LED display, allowing for quick and easy switching between current and voltage readings • Custom Calibration Options: Ensure accuracy with built-in calibration potentiometers for current and voltage, enabling you to adjust displayed values as needed • Versatile Applications: Ideal for various tasks including signal generation, valve adjustment, PLC debugging, and LED testing, making it a valuable tool in any setup • High Precision Performance: Enjoy precise adjustments with dual tuning modes, achieving a minimum increment of 0.01mA and a low actual error for reliable output quality Features: 1、AMP and VOLT Dual Signal: The multifunctional signal generator kit can generate ampere and voltage through one module, just rotate a multi cycle potentiometer to generate 4 to 20mA current signal, which is simple and convenient. 2、Clear LED Display: Our 4 to 20mA signal generator features a bright and clear 4 digit LED digital display that can be used to monitor output current and voltage. You can easily switch monitors by simply pring the switch under the monitor. 3、Ampere and Voltage Display Calibration: There are current and voltage display calibration potentiometers on the back of the module. If the display is not accurate, you can calibrate the displayed value of the current voltage yourself. 4、Wide Range of Applications: Our signal adapters can be used for signal generators, valve adjustment, inverter control, PLC debugging, panel debugging, LED testing, analog transmitter output. 5、Good Performance: Coarse and fine tuning dual modes, and the number of turns can be set separately. The minimum adjustment number of the knob is 0.01mA, the last number is added or subtracted by 1. After calibration, the actual error is 0.01mA, and the high accuracy linear output is obtained. 6、Reliable Performance: 4 bit 0.4 inch high brightn large digital tube, the display is clearly visible. Digital encoder knob, and unaffected by the environment. Power supply with reverse polarity protection. The output can be short circuited.
