Connections/Power supply

The power is supplied by three 1.5 V batteries (round cells
size AA) commercially available. The battery voltage must be
> 3.3 V. Otherwise the HE lite switches off automatically! A
faulty measuring due to low battery is not possible. By
means of the option »battery« (refer to chapter 7.1) the
supply voltage can be checked. Prior to the measurement
the warning notice »Bat < 3.3 V« appears on the display.
The old battery then has to be replaced by a new one. For this purpose the battery box must
be opened at the bottom surface.
Pay attention to the »+« and »–« marking when replacing the batteries. Bend the nozzle of
the cover forwards after closing the battery box, until it locks into place.
Attention!
A battery cannot be recharged! This can lead to a dangerous escape of acid.
