3. Power supply
This equipment is powered by an internal rechargeable battery (12 V -
2.3 Ah).
3.1. Battery status check
During the measurement, it is possible to check the battery status. The
key must be pressed. If the battery charge is enough, it will read
"BAT OK". If the charge is not enough, the message will be "LOW BAT",
and the battery should be recharged. The analogue bargraph will give an
approximated idea of the remaining charge percentage (at least 20% is
required for a normal operation).
When the battery charge reaches the normal operation minimum value,
the message "LO BAT" appears automatically in the area where the test
voltage value is indicated.
