6 Measuring Voltage and Frequency
Select the Measuring Function
Switching Back and Forth Between Single and 3-Phase Measure-
ment
Press the softkey shown at the left in order to switch
back and forth between single and 3-phase mea-
surement. The selected phase measurement is dis-
played inversely (white on black).
6.1 Single-Phase Measurement
Connection
6.1.1 Voltage Between L and N (U
L-N
),
L and PE
(U
L-PE
)
a
nd N and PE
(U
N-PE
) with Country-Specific Measuring
Adapter, e.g. SCHUKO
Press the softkey shown at the left in order to switch
back and forth between the country-specific mea-
suring adapter, e.g. PRO-Schuko measuring adapter
(Z503K), and 2-pole measurement with the KS-PROF-
ITEST INTRO (Z503L). The selected connection type is
displayed inversely (white on black).
6.1.2 Voltage Between L – PE, N – PE and L – L
with 2-Pole Connection
Press the softkey shown at the left in order to switch
back and forth between the country-specific mea-
suring adapter, e.g. PRO-Schuko measuring adapter
(Z503K), and 2-pole measurement with the KS-
PROFITEST INTRO (Z503L). The selected connection
type is displayed inversely (white on black).
Refer to section 5.8 regarding 2-pole measurement with fast or
semiautomatic polarity reversal.
