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). Operation is possible with the mains unit connected.
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).
