6.2. Testing of extension cables
6.2.1. RPE – Protective conductor resistance
Before testing
The maximum testing current for RPE meas-
urement is 10 A!
The rotary switch of the
BENNING MA 3 can be
used for RPE measure-
ment in any locking posi-
tion.
Before starting the test, determine the internal RPE re-
sistance of the measuring adapter.
Internal RPE resistance of the measuring adapter
RPE – BENNING MA 3

Start the RPE measurement on your appliance
tester.

Contact the test probe of the appliance tester with
the PE contact of the corresponding CEE
socket
(see figure “ RPE – BENNING MA 3 ”).

Write down the measured RPE value.

Follow the test procedure Class I, RPE for “ porta-
ble test samples ”.
The manufacturer recommends to write down
the known measured RPE values of all CEE
connections of the BENNING MA 3 for future
measurements and add them to the measuring
adapter.

Cable test

Connect both cable connections to the corresponding
CEE sockets of the BENNING MA 3 .

Connect the test probe of your appliance tester to the
PE socket (see pos. 1 , chapter 4 ) of the BEN-
NING MA 3 .

Start the RPE measurement on your appliance tester.

Read the RPE measuring result shown on the display of
the appliance tester.

Subtract the measured RPE value of the BENNING MA
3 from the RPE measuring result of the test sample.
As a result, you will obtain the measured RPE value of the
test sample.

Edit the measured RPE value in the appliance tester ac-
cording to the calculated measuring value.
