10.2.4 RISO – Probe-Probe (GND)

Insulation Resistance Measurement, PC III

This measurement is intended exclusively for 
protection class III DUTs.
Insulation resistance between two points 
(e.g. components) can be determined with 
this measurement.
The test voltage and the limit value are 
adjustable.
This measurement is not performed if there 
are no insulated, conductive parts.
Conductive insulated parts must be con-
tacted one after the other.
Measurement is performed with the DUT in 
the de-energized state.
Measurement is conducted with a test volt-
age of 250 or 500 V.

Connection

➭

Connect the first probe to the black GND 
socket.

➭

Connect the second probe to the red 
probe socket.

➭

Connect phase conductors L1, L2 and 
L3 to N and the red probe.

➭

Connect PE to the black probe.

Procedure

➭

Press the 

R

ISO

 key.

➭

Select the “

Probe-Probe

” menu with the 

help of the 



 scroll keys.

➭

Start the measurement by pressing the 

OK

 

key.

➭

Review the preconfigured parameters for 
the limit value (0.3/1/2 M

) and for test 

voltage (250 V/500 V), select them if 
necessary using the 

 

 scroll keys and 

adjust them to the momentary values 
using the 



 scroll keys.

Heating Elements:

 “Yes” results in a reduction 

of the permissible limit value of 1 M

 to 

0.3 M

.

Test Voltage:

 In the case of devices with inte-

grated surge arrester, insulation resistance 
measurements performed with 500 V may 
lead to 
“excessively small” measurement results. 
Reducing test voltage to 250 V makes it 
possible to perform measurement without 
activating overvoltage protection.

➭

Contact the short-circuited L and N pins 
in the DUT’s mains plug with the first 
probe.

➭

Contact all of the DUT’s insulated, con-
ductive parts with the second probe.

➭

If the respective measured value is larger 
than the specified limit value, 

OK

 appears 

at the display and the 

 LED lights up 

green.

➭

You can repeat the measurement by 
pressing the 

 scroll key (reset), after 

which the LED 

 goes out briefly until 

the next measurement is performed.
