Power-on Inspection
Before connecting the instrument to a power source, please select the AC
voltage selector on the rear panel of your multimeter according to the power
supply. Then connect the power line to the socket on the rear panel of the
multimeter.
Note: To avoid electric shock, make sure that the instrument is correctly
grounded to the earth before connecting AC power.
The boot screen will appear after pressing the power-on button. To restore the
instrument configuration to factory default settings:
Press [Shift] > [Utility] > Store/Recall >Set To Defaults
