REGULAR MAINTENANCE OF REPLACEABLE F PLUGS

8
Note: Your new measuring instrument is equipped with replaceable F
plugs that must be checked and replaced at regular intervals to
ensure continued reliable performance.
To remove the plugs, use a 7/16 inch/11 mm spanner with torque
setting 1 Nm.
Clean the surrounding area carefully with a lint-free cloth to prevent
deposits from falling into the F plug hole.
Tip: Check whether any copper fragments have collected in the F plug
on the measuring device. If necessary, these can be removed
using a dry cotton bud.
