Note!
Removing the Batteries During Periods of Non-Use
The integrated quartz movement draws power from the batteries
even when the instrument is switched off. It is advisable to
remove the batteries during long periods of non-use for this rea-
son (e.g. vacation). This prevents excessive depletion of the bat-
tery, which may result in damage under unfavorable conditions.
Note!
Battery Replacement
Stored measurement data is lost when the batteries are replaced.
In order to prevent data loss, it is advisable to backup your data
to a PC with the help of DranWin 10 software before replacing
the batteries. The selected operating parameters remain in mem-
ory, although date and time must be reentered.
Battery
The current battery charge level can be queried in the “

2.75 V.
Make sure that no battery leakage has occurred before initial start-up,
as well as after long periods of storage. Continue to inspect the batter-
ies for leakage at short, regular intervals.
If battery leakage has occurred, carefully and completely clean the
electrolyte from the instrument with a damp cloth, and replace the bat-
teries before using the instrument.
If the “
” symbol appears at the display, the batteries should be re-
placed as soon as possible. You can continue working with the instru-
ment, but reduced measuring accuracy may result.
The instrument requires two 1.5 V batteries in accordance with
IEC R 6 or IEC LR 6, or two equivalent rechargeable NiCd batteries.
