12.1 Battery
Note!
☞
Removing the Battery During Periods of Non-Use
The integrated quartz movement draws power from
the battery, even when the calibrator is switched off.
It is advisable to remove the battery during long peri-
ods of non-use for this reason (e.g. vacation). This
prevents excessive depletion of the battery, which
may result in damage under unfavorable conditions.
The current battery charge level can be queried in the “Info”
menu:

Make sure that no battery leakage has occurred before initial
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 the electrolyte from the instrument with a damp cloth,
and replace the batteries before using the instrument.
If the “
” symbol appears at the display, the batteries should
be replaced as soon as possible.
The instrument requires three 1.5 V batteries in accordance
with IEC R 6 or IEC LR 6, or equivalent rechargeable batter-
ies.
Replacing the Batteries
➭
Set the instrument face down onto a flat working surface,
loosen the two screws at the back and lift off the housing
base, starting at the bottom. The housing top and hous-
ing bottom are held together with the help of snap hooks
at the top front.
➭
Remove the batteries from the battery compartment.
➭
Insert three 1.5 V mignon cells into the battery compart-
ment, making sure that the plus and minus poles match
up with the provided polarity symbols.
➭
Important for reassembly: First set the housing base onto
the housing top and align accurately (see photo below).
Then press the two housing halves together, first at the
bottom front (a), and then at the top front (b).
➭
Secure the housing base with the two screws.
➭
Please dispose of depleted batteries in accordance with
environmental protection regulations!
12.2 Power Pack
Use only the NA5/600 power pack from GOSSEN METRA-
WATT GMBH in combination with your instrument. This
assures operator safety by means of an extremely well insu-
lated cable, and safe electrical isolation (nominal secondary
ratings: 5 V/600 mA). Installed batteries are disconnected
electronically if the power pack is used, and need not be
removed from the instrument.
