Commissioning
56
The instrument is ready for operation.
Note
The measuring instrument was calibrated and tested by the
manufacturer before delivery. Consequently, you can begin
measuring immediately. However, we recommend perform-
ing a calibration again following the initial commissioning
(see section 4.3 C
ALIBRATION
). Thus, you will quickly be-
come familiar with operating the measuring instrument and
the calibration procedure.
1 Place the instrument with the operating panel face
down on a soft surface.
2 Undo the two screws (1).
3 Open the lid of the battery compartment (2).
4 Insert the batteries (3). While doing so, check that the
poles are correct according to the diagram in the bat-
tery compartment.
5 Replace the lid of the battery compartment.
6 Attach the lid with the two screws. At the same time,
make sure that the sealing gasket around the battery
compartment (4) forms a tight seal with the lid.
