measurement is displayed inverse (white on black).
6.1 Single Phase Measurement
Connection
A probe must be set for measuring probe voltage U
S-PE
.
6.1.1 Voltage between L and N (U
L-N
), L and PE (U
L-PE
),
as well as N and PE (U
N-PE
) for country-specific plug
insert, e.g. SCHUKO
Repeatedly press the sofkey shown at the left in
order to switch back and forth between the country-
specific plug insert, e.g. SCHUKO, and the 2-pole

for connection of 2-pole adapter
Repeatedly press the sofkey shown at the left in
order to switch back and forth between the country-
specific plug insert, e.g. SCHUKO, and the 2-pole
adapter. The selected connection type is displayed
