SECUTEST ST BASE(10) / PRO and SECULIFE ST BASE(25)
24 Gossen Metrawatt GmbH
12.3 Measurement of insulation resistance and
equivalent leakage current
(alternative leakage current measuring
method)
Attention!
!
Electric shock!
Risk of Consequential Accidents!
Testing is conducted with up to
500 V. If terminals L or N at the test
socket or the test probe are touched,
electric shock may occur which
could result in consequential acci-
dents.
Do not touch terminals L or N at the
test socket or the test probe.
12.4 Measuring Parameters for Single
Measurements and Test Sequences
Measuring parameters which apply to indi-
vidual measurements, as well as to test
sequences, must be entered in the SETUP
switch position.

System
(Yes/No)
Yes: active leakage current mea-
surements (or all measurements with
reference to PE at the mains connec-
tion side) are disabled. Test se-
quences which include measure-
ments of this sort are also disabled.
Ref. Voltage L-PE
(110 V, 115 V, 220
V, 230 V, 240 V)
Reference (line) voltage is the volt-
age to which the measured values
for leakage current have been stan-
dardized.
It’s used in the case of leakage cur-
rent to mathematically adjust mea-
sured current values to the specified
voltage.
Measurements with line voltage
at the test socket:
The setting value has no influence
on the voltage with which the test
object is supplied via the test instru-
ment’s test socket.
Leakage current measurements
with “Alternative” measurement
type: The setpoint value of the syn-
thetic test voltage is derived from the
value specified here.
Alt. Test Freq.
(48 Hz ... 400 Hz)
Selectable frequency setpoint value
for synthetic test voltage for all leak-
age current measurements of mea-
surement type “Alternative”, affecting
the following measurements and/or
rotary selector switch positions:
– Single Measurements
(rotary switch level: green)
– Measurements in integrated test
sequences
– Measurements in user-defined
test sequences
