Internal battery powered, rechargeable, 12 V - 7 Ah.
At the end of the useful life, the battery has to be recycled or disposed of
properly in order to take care of the environment.
3.1. Battery condition
The charge condition of the battery can be verified before or during the
resistance measurement. In order to achieve that, the operator has to
press the battery key while the equipment is turned on. The bargraph
shows remaining charge as a percentile value. If during measurement the
charge of the battery achieves a critical level, the display will show the
BAT message notifying that the charge level is low. After a few minutes
the measurement will be automatically interrupted in order to preserve the
battery from a deep discharge that is prejudicial for its expected useful
life.
3.2. Battery charger
The built-in battery charger is always active when the equipment is
connected to the mains supply, even if the On/Off switch is turned off.
Charging procedure:
•
Check that the On/Off switch is in Off.
•
Connect the equipment to the mains supply.
•
The battery charge indicator will keep on lightning with a red light
up to completing the charge. At that point, it will change to a green light,
being like this up to the equipment disconnection from the mains supply.
If the ON/OFF switch was pressed, the display will indicate
CHARGING BAT.
