Before using
Before initial use, remove the protective film
from the device display
10
and insert the
enclosed battery.
Inserting / changing
the battery
If the battery symbol appears in the
display
10
, the inserted battery is almost drained
and must be replaced. Empty batteries can falsify
the measured result.
To insert the battery proceed as follows:
Open the battery compartment cover
12
on
the back of the device. You can remove the
used battery more easily with the aid of the
material strip, which is inside the battery
compartment. Just pull on the material strip.
Remove the used battery.
Plug the contacts of the 9 V-blockbattery on
the contacts of the profiled plug. Make sure
you fit the batteries the right way round. This
is specified by the profiled shape of the con-
tacts. Also ensure without fail that the material
strip is underneath the battery.
Insert the battery in the battery compartment
and close the cover again, so that it audibly
latches into place.
