10. How to use the protective rubber holster
- The safety test leads can be stored by wrapping them around the protec-
tive rubber holster  and then clipping the probes into the protective probe
holders on the rear of the holster  (see figure 9).
- A safety test lead can be clipped into the probe holder on the protective
rubber holster  with the test probe protruding, in order to apply the probe
together with the BENNING MM 1 to a measuring point (see figure 10).
- The rear tilt stand on the protective rubber holster  allows the
BENNING MM 1 to be placed standing upright (for easier display reading)
or hung up (see figure 11).
- The protective rubber holster  can also be hung on a nail if so desired.
