1.2 Batteries

When connected to an installation, the instruments battery compartment can contain hazardous
voltage inside! When replacing battery cells or before opening the battery/fuse compartment
cover, disconnect any measuring accessory connected to the instrument and turn off the
instrument.
• Ensure that the battery cells are inserted correctly otherwise the instrument will not operate and
the batteries could be discharged.
• If the instrument is not to be used for a long period of time, remove all batteries from the battery
compartment.
• Rechargeable Ni-MH batteries (size AA) can be used. It is recommended only using of
rechargeable batteries with a capacity of 2300mAh or above.
• Do not recharge alkaline battery cells!
1.3 Precautions on charging of new battery cells or cells unused for a
longer period
Unpredictable chemical processes can occur during the charging of new battery cells or cells that
have been left unused for long periods of time (more than 3 months).
Notes:
• The charger in the instrument is a pack cell charger. This means that the cells are connected in
series during the charging so all of them must be in similar state (similarly charged, same type
and age).
• If even one deteriorated battery cell (or just one of a different type) can cause disrupted charging
of the entire battery pack which could lead to overheating of the battery pack and a significant
decrease in the operating time.
• If no improvement is achieved after performing several charging/discharging cycles, the state of
each individual battery cells should be determined (by comparing battery voltages, checking them
in a cell charger, etc). It is very likely that one or more of the battery cells could have deteriorated.
• The effects described above should not be mixed with the normal battery capacity decrease over
time. All charging batteries lose some of their capacity when repeatedly charged/discharged.
The actual decrease in capacity compared to the number of charging cycles depends on the
battery type. This information is normally provided in the technical specification from battery
manufacturer.
