1. Set the value of rated phase-to-earth, phase-to-neutral or phase-to-phase voltage (see
§ 4.2.11)
2. Set the limit value of contact voltage (see § 4.2.10)
3. Select position

5.
For Loop L-PE measurements,
in case the cable with Shuko plug is used, insert the
red conductor into input terminal
V
L
and the green conductor into input terminal
COM/E/N
and connect the instrument to the system to be tested (see Fig. 23). The
value of voltage Phase-Earth is shown on the display
