Three-phase energy meter field calibrator

2.8 Mode of power supply

The instrument is provided with automatic and manual selection mode of power supply, which

are switched by

F4

key (switch from manual to automatic mode by pressing

F4

key)

When the instrument is in the automatic selection mode of power supply, the power mode

identifier is yellow; when it is in the manual selection mode of power supply, the power mode
identifier is red.

The automatic selection mode of power supply has three methods of power supply, that is,

adapter power supply, voltage terminal and battery power supply; when it is in the automatic
selection mode of power supply, the priority of the instrument’s mode of power supply is adapter
power supply, voltage terminal and battery power supply; when it is in the instrument’s manual
power mode, you can use

F4

key to force and select the terminal power supply or battery.

2.81 Battery power supply

When the battery power supply is manually selected for the instrument, the battery status

identifier at the lower right corner of the instrument screen is red battery icon (as shown on:

) press

F4

to switch to the terminal power supply.

When a mode of power supply is automatically selected, the battery status identifier at the

lower right corner of the instrument screen is yellow battery icon.
