Creating the PE/earthing terminal

As the testo 6381 has a metal housing, we recommend that the
instrument be earthed. This can be done using the earthing
terminal within the instrument (1) or the earthing terminal outside of
the instrument (2).
Using the earthing terminal within the instrument
1. Guide shielded cable (5) through the cable coupling (x) and fit
cable lug (8). Fix this to the side of the instrument (6) using M 5

Only use the external earthing terminal in dry interiors.
