10. How to use the protective rubber holster

- The safety measuring leads can be stored by coiling them round the protective rubber
holster O and clipping the probe into the holster O so that they are sufficiently protected
(see fig. 14).
- You can clip one lead onto the protective rubber holster O in such a way that the measuring
probe projects. This allows you to bring the measuring probe and the BENNING MM 12 up
to the measuring point together.
- The support at the back of the holster O can be used to prop the BENNING MM 12 up in
a diagonal position (to make reading easier) or to suspend it (see fig. 15).
- The protective rubber holster O has an eyelet for suspending the unit in a convenient posi-
tion.
