6 Measuring Alternating Voltage and Frequency
Select the Measuring Function
Switching Back and Forth Between Single and 3-Phase Measure-
ment
Repeatedly press the softkey shown at the left in
order to switch back and forth between single and
3-phase measurement. The selected phase
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
adapter. The selected connection type is displayed
inverse (white on black).
6.1.2
Voltage between
L – PE, N – PE and L – L
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
inverse (white on black).
Setting Parameters
2-pole measurement with fast or semiautomatic polarity reversal,
see section 5.8.
