Calibration
26
The batteries can be recharged even while they
are located in the meter.
NOTE!
It is possible to operate the meter when charging
is in progress.
ATTENTION!
Ensure rechargeable batteries are equipped in the
meter before charging. Never try to charge dis-
posable batteries. Use 4 AA rechargeable batter-
ies only.
NOTE!
To ensure maximum capacity use batteries of
same age and condition only. Always replace a
full set of batteries when necessary.
We recommend to send the meter to Wöhler for
calibration every year.
