Presence of dangerous voltage
Dangerous voltage may be present on the battery and battery contacts in
the battery compartment.
Touching the battery or battery contacts could result in severe personal
injury or death.
Only remove and replace the battery with the existing battery holder
without touching the contacts.
Wrong battery type
Replacing the battery with the wrong type or voltage rating could result in
damage to the meter.
Only use a lithium battery with a rated voltage of 6 V and the same
construction as the original battery (type CR-P2) as a replacement.
Battery replacement after a long period of non-use
If the meter has been disconnected from the supply for a long time, the
power reserve is exhausted. Replacing the battery when the power reserve
is exhausted may lead to an invalid time/date information without the
corresponding error message.
Reconnect the meter to the measurement voltage or auxiliary power supply
before replacing the battery.
1. Remove the front door seal and open the front door.
2. Lightly press the latch of the plastic battery holder until it releases and
then withdraw the battery holder with the old battery.
3. Mark the current date on the new battery.
4. Draw the old battery from the holder and insert the new 6 volt rated
lithium battery.
