Note
Removing the Batteries During Periods of Non-Use
The integrated quartz movement draws power from the bat-
teries even when the instrument is switched off. It's advis-
able to remove the batteries during long periods of non-use
for this reason (e.g. vacation). This prevents excessive
depletion of the batteries, which may result in damage under
unfavorable conditions.

are replaced. The selected operating parameters remain in
memory, although date and time must be reentered.

SETUP ENTER
Make sure that no battery leakage has occurred before initial start-
up, as well as after long periods of storage. Continue to inspect the
batteries 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
battery before using the instrument.
If the " " symbol appears at the display, the batteries should be
replaced as soon as possible. You can continue working with the
instrument, 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 NiMH batte-
ries.
