Activate the PRCD.

➭

Perform the measurement as described 
in the operating instructions for the 

PROFITEST MXTRA

 (section 12.2 as of V10).

4.2

Measuring Insulation Resistance (Riso)

Attention!

!

The right-hand rotary selector switch 
must be set to the mains disconnect 
position: 

1~ OFF

 or 

3~ OFF

.

➭

In order to perform the insulation mea-
surement (Rins), connect the 

PROFITEST 

MXTRA

 test instrument, via the measuring 

adapter, to socket 9 for the cable at the 
mains side and to socket 10 for the 
cable at the test object’s outlet side.

Example, Single-Phase PRCD OUT Sockets

➭

Connect the PRCD as described in sec-
tion 3.3.

➭

Single-phase PRCD:

 Connect the 

PROFITEST MXTRA

 test instrument, via the 

2-pole measuring adapter, to the 

PRCD IN 

/ OUT

 L1, N and PE sockets, one after the 

other.

➭

Perform the measurement as described 
in section 11 of the operating instruc-
tions for the 

PROFITEST MXTRA

. 

➭

3-phase PRCD:

 Connect the 

PROFITEST 

MXTRA

 test instrument, via the 2-pole mea-

suring adapter, to the 

PRCD IN / OUT

 L1, L2, 

L3, N and PE sockets, one after the other.

4.3

Tripping Test with Nominal Residual Cur-
rent and Measurement of Time to Trip

Note!

If you operate your test adapter at an 
electrical system with a 30 mA breaker, 
the mains RCCB may be tripped during 
the tripping test (tripping current and 
time to trip) instead of the PRCD. In this 
case the 

MAINS L1

 LED goes out.

In order to prevent an upstream RCD (also 
non-selevtive RCD) from being tripped and 
to ensure that the actual tripping current 
and/or the correct time-to-trip are deter-
mined, we recommend the following proce-
dure (except for PRCD-K):

➭

Connect the 

PROFITEST MXTRA

 test instru-

ment via the 2-pole measuring adapter 
with pole (L1) to L1 (PRCD-OUT) and 
with pole (PE) to N (PRCD-IN). 
Observe the correct polarity between 
earthing contact plug and PRCD!

Exception type K PRCDs

➭

Connect the 

PROFITEST MXTRA

 test instru-

ment via the 2-pole measuring adapter 
with pole (L1) to L1 (PRCD-OUT) and 
with pole (PE) to PE (PRCD-OUT). 
Observe the correct polarity between 
earthing contact plug and PRCD! 
Optionally you can connect the 

PROFIT-

EST MXTRA

 test instrument with the out-

put of the type K PRCD via the PRO-
SCHUKO adapter.

➭

Refer to the operating instructions for the 

PROFITEST MXTRA
