A backlight saver can be activated after a specified number of minutes during which
no operation key is pressed. The backlight saver turns off the backlight of the LCD,
prolonging the lifetime of the backlight by turning it off when not needed.
To deactivate the backlight saver, press any key. The operating screen appears
again.
While the backlight saver is active, the instrument’s measuring state is still indicated
by the LED (lights green when measuring, and blinks when not measuring).
Be aware that power is still consumed even when the backlight is off, so be sure to
turn the instrument’s power switch off when not in use.
The screen color scheme can be selected from
2 colors.
The beeper can be set to sound when an error occurs.
