- Lift the front end at its bottom section and carefully remove the same.
- Lift one end of the defective fuse from the fuse holder.
- Fully push the defective fuse out of the fuse holder.
- Fit the new fuse with the same rated current, rated voltage, same discon-
nection capacity, same trigger characteristics, and same dimensions.
- Make sure that the new fuse is seated centred in the holder.
- Order the battery supply lines such that they are not crushed between the
housing parts.
- Engage the front end on the housing bottom and fit the three screws.
- The battery must be connected to the battery supply lines and placed in the

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).
- You can engage a safety measuring lead to the rubber protection frame
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.
- The rear support on the rubber protection frame
provides for an inclined
set-up of the BENNING MM 11 (facilitates reading) or attachment (see
Figure 15).
- The rubber protection frame
is fitted with a lug which can be freely used
for an attachment option.
