Warning!
Ex Environment: Remove the instrument from the
potentially explosive environment before opening.
Attention!
!
Non-Ex Environment: Disconnect the instrument
from the measuring circuit before opening to re-
place batteries!
Removing the Batteries During Periods of Non-Use
The integrated quartz clock draws power from the batter-
ies, even when the instrument is switched off. It is 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.
Checking Battery Voltage-Level and Condition
The current battery voltage level can be queried in the
“Info” menu (see chapter 8 on page 17):
MENU/ESC + ON|OFF  InF0 X.X V (bAtt).
Make sure that no battery leakage has occurred before ini-
tial start-up, and 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 electrolyte from the instrument with a damp
cloth, and replace the batteries before using the instru-
ment.
– If the “ ” symbol appears at the display, the batteries
should be replaced as soon as possible. You can con-
tinue working with the instrument, but reduced mea-
suring accuracy may result.
