Operating analyser with Nickel -Metal-Hybrid (NiHM)-Battery

►

Please note that the following information is only relevant for you if an

optional NiHM-Battery is installed in your analyser.

The NiHM-Battery is mounted in the analyser instead of a LiIon-Battery.
The optional NiHM-Battery is intended for air travel, because the

Regulations for the transport of LiIon-Battery during air travel can often be
problematic.

►

Note that the NiHM-Battery is not intended for measurement operation,

as only a limited Battery life is available.

►

Measure only with a connected power supply.

Note that the analyser can be used for about 30 minutes in battery mode.

►

Use the analyser in battery mode only for short measuring point changes.

Furthermore, short power failures can be bridged by battery mode.

►

The analyser displays a message if no power supply is connected.



The message appears 45 seconds after switching on.



The message appears after 90 seconds if the power supply unit is re-

moved during operation.
