6.1
Monitoring of the battery charge status
The device is equipped with a Li-Ion battery pack 11.1 V 3.4 Ah. The battery pack includes a
circuit monitoring its charge status, which provides precise level of battery pack charge and a
temperature sensor.
The charging level of the battery pack is indicated by icon on the top bar of the screen on the
right side
6.2
Replacing rechargeable batteries
MPI-535 meter is powered from SONEL LiIon rechargeable battery pack.
Battery charger is installed inside the meter and cooperates only with the manufacturer’s re-
chargeable battery pack. The charger is powered by external power supply adapter. It can be also
powered from the car cigarette lighter socket. Both the rechargeable battery pack and the adapter
are standard components of the meter.
WARNING
If the test leads are left in the terminals during replacement of the batteries,
there is a risk of electric shock with a dangerous voltage.
6.3
Charging the rechargeable batteries
Charging the battery pack of the device is started automatically after connecting:
2 V DC power supply adapter,
charging cable for the car cigarette lighter.
Charging is indicated by the
icon next to the battery symbol on the top bar and by the
H.V./REC/CONT.
diode. The temperature of the battery and the ambient temperature influence
the charging process. If the battery temperature is below 0°C or higher than 45°C, the charging
process is stopped.
