Battery charger is installed inside the meter and
cooperates only with the manufacturer’s recharge-
able battery pack. The charger is powered by external power supply adapter. The device may be also
powered from the car cigarette lighter socket (
12V only
), using an optional charger.
Charging commences once the power supply has been connected to the meter regardless of the
fact whether the meter is on or off (only the charging mode is different - as described below). When the
meter is switched off - the charging process is indicated on the screen by displaying animated symbol
of battery being charged; when the meter is switched off - the charging is indicated by blinking LED's of
measurement functions (they blink consecutively in red).
Charging modes:
