4 Operation

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).
