  3 CH outputs，High precision Display

  3 independent outputs, 4-digit voltage and current high-precision display: 10mV/1mA

  

  Five sets of settings to save and recall

  Five groups of M1~M5 settings are saved and recalled, long press to store and short press to recall, making the test work efficient and convenient.

  

  Buzzer switch and key lock function, shutdown memory function, SET VIEW function

  Buzzer switch: switch the buzzer according to the working environment Key lock function: prevent accidental touch and wrong setting during normal working process Shutdown memory function: restore the last saved setting value next time the machine is turned on SET VIEW function: call preset value with one key

  

  Remote control DIGITAL I/O interface

  The remote control power supply CH1/CH2 channels can be output and closed through DIGITAL I/O terminals
