10. Application of rubber protection frame

- You can store the safety measuring leads by winding the safety measuring
leads around the rubber protection frame  and engaging the tips of the
safety measuring leads with protection against the rubber protection frame
 (see Figure 14).

such that the measuring tip protrudes freely, in order to be able to apply the
measuring tip - jointly with the BENNING MM 11 - to a measuring point.
