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.

Setup 1/3 > All Measurements

Meas. Parameter Meaning

Measuring at IT 
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 
(only with DSECUTEST DB+ – 
Z853R or feature KB01)
