4 Measurements with the

PROFITEST MXTRA

In order to perform protective conductor mea-

surements (Rlo) at

type S PRCDs

with the

PROFITEST

MXTRA

, the test adapter must remain connected

to the mains.

The test adapter can remain connected to the

mains for protective conductor measurements

conducted at PRCDs whose protective conduc-

tor is not switched, as well as for insulation mea-

surements (Rins) with the

PROFITEST MXTRA

4.1 Measuring Protective Conductor

Resistance (Rlo)

As opposed to the usual default setting for

low-resistance measurements, the device

under test does not have to be discon-

nected from all sources of voltage in this

case. Depending on the PRCD, the rotary

selector switches have to be set to the ON

and the 1~ ON or 3~ ON positions, in order to

be able to activate the PRCD and switch the

protective conductor through.

Example of a Single-Phase PRCD

➭ Before performing protective conductor

measurements, execute an offset mea-

surement to assure that the test

adapter’s connector contacts are not in-

cluded in the measurement results.

➭ Insert the respective test plug into the

appropriate socket at the test adapter to

this end: 2 to 4 or 1 to 6.

➭ Start the offset measurement at the

PROFITEST MXTRA

➭ Connect the PRCD as described in sec-

tion 3.3.

➭ Connect the PROFITEST MXTRA test instru-

ment to sockets 9 and 10 via the 2-pole

measuring adapter.
