Function | Explain |
Reset | In shutdown mode,press the power key for more than 5S to reset all parameters and startup |
Toggle display | Display Mode 2:+,-Key Switch |
Display Mode 3:+,-Key Switch | |
Turn on/off | Short press the power key for operation |
Quickly voltage adjustment | In the boot state,click the'+'key quickly |
Quickly current adjustment | In the boot state,click the'-'key quickly |
Setting error | When the overvoltage is set beow the undervoltage,the protector will always be in the protection state |
Reference of calibration table | When correcting the voltage/curent,the adjustment must be made with reference to the multimeter with root mean square(RMS) |
