Other operation

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
Toggle display	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)
