4.1.2 Measuring Insulation Resistance with
the PROFITEST PRIME
Preparing for Measurement
➭ Using the corresponding test probes,
connect the test instrument to the L, N
and PE sockets at the test adapter.
➭ Disconnect the system from all sources
of voltage before connecting the mea-
suring points to the test adapter.
➭ Connect the system to sockets L1, L2,
L3, N and PE.
Performing the Measurement
Attention!
!
Insulation test voltage may not ex-
ceed 500 V.
➭ Perform the measurement as described
in the operating instructions for the test
instrument:
PROFITEST PRIME: sections 8.6 and 11
➭ The following measuring functions are
available for the measurement of insula-
tion resistance: insulation measurement
with constant voltage and insula-
tion measurement with rising test voltage
.
