9.5­­ Calibration
To maintain the specified precision of the measurement results, the instrument
must be recalibrated at regular intervals by our factory service. We recom-
mend a recalibration interval of one year. Send the appliance to the following

- The safety test leads can be stored by coiling them round the protective
rubber holster  and clipping the probe into the holster  so that they are
sufficiently protected (see fig. 14)
- You can clip one lead onto the protective rubber holster  in such a way
that the measuring probe projects. This allows you to bring the measuring
probe and the BENNING MM 7 up to the measuring point together.
- The support at the back of the holster  can be used to prop the
BENNING MM 7 up in a diagonal position (to make reading easier) or to
suspend it (see fig. 15).
- The protective rubber holster  has an eyelet for suspending the unit in a
convenient position.
