for around 8 minutes. At that time, the Meter consumes
around 10µA current.
The Meter can be activated by pressing the POWER two
times.

The Meter has a built-in sensor. Therefore the Display
Backlight turns on and off automatically depending on

the Display Backlight turns on automatically while in a
bright condition, the Display Backlight turns off automatically.
