1.Auto power off (When the instrument knob and the four buttons are not responding in 30 minutes, Instruments into sleep mode.
In the sleep mode, rotate button and the instrument will auto power on
2.In the sleep mode, press SELECT button to wake up instrument,auto power off function will be cancelled.
3.After testing Hz/% and returning to DCV and ACV, the slot range is DCV-400mV, ACV-4V.
AUTO disappears in the LCD. At this time testing higher voltage,the instrument must be powered off and reset DCV, ACV for automatic range.
