3.2 Power supply
The power is supplied to the instrument via a replaceable rechargeable battery
or the mains unit provided (battery must be inserted).
With an attached mains unit, power is supplied automatically via the mains unit
and the rechargeable battery is charged (only at ambient temperatures from 0
to 40°C).
If the instrument is switched off when connected to a PC via the USB interface,
the rechargeable battery is charged via the USB interface.
It is also possible to charge the battery using a charging station (accessory).
The instrument is equipped with a buffer battery to maintain the system data
during an interruption in the power supply (e.g. when the battery is changed).

The camera starts.
The start screen appears on the
display.
The camera carries out automatic zeroing approx. every 60 seconds in
order to guarantee measuring accuracy. A "click" is heard when this
happens. The image freezes briefly when this occurs. Zeroing is carried
out more frequently during the camera warm-up period (takes
approx. 90 seconds).
During the warm-up period no measuring accuracy is guaranteed. The
image can already be used for indication purposes and saved.
