Screw the cover on the instrument.
Warnings!
Hazardous voltages exist inside the instrument. Disconnect all test leads, remove the power
supply cable and turn off the instrument before removing battery compartment cover.
Use only power supply adapter/charger delivered from manufacturer or distributor of the
equipment to avoid possible fire or electric shock.
Do not use standard batteries while power supply adapter/charger is connected, otherwise
they may explode!
Do not mix batteries of different types, brands, ages, or charge levels.
When charging batteries for the first time, make sure to charge batteries for at least 24 hours
before switching on the instrument.
Notes:
Rechargeable NiMH batteries, type HR 6 (size AA), are recommended. The charging time and the
operating hours are given for batteries with a nominal capacity of 2400 mAh.
If the instrument is not going to be used for a long period of time remove all batteries from the
battery compartment. The enclosed batteries can supply the instrument for approx. 5 to 7 hours
(MI 2892/2885); and 3 to 5 hours (MI 2893) (depends on the battery state, environmental
conditions etc).
7.2
Batteries
Instrument contains rechargeable NiMH batteries. These batteries should only be replaced with the
same type as defined on the battery placement label or in this manual.
If it is necessary to replace batteries, all six have to be replaced. Ensure that the batteries are inserted
with the correct polarity; incorrect polarity can damage the batteries and/or the instrument.
Precautions on charging new batteries or batteries unused for a longer period
Unpredictable chemical processes can occur during charging new batteries or batteries that were
unused for a longer period of time (more than 3 months). NiMH and NiCd batteries are affected to a
various degree (sometimes called as memory effect). As a result, the instrument operation time can be
significantly reduced at the initial charging/discharging cycles.
