LOOP Re at distribution board
LOOP Re at wall socket
Figure F.2: Examples of LOOP Re measurement results
Displayed results:
Re..............Resistance of PE wiring at distribution board.
Rpe............Resistance of PE wiring between distribution board and wall socket.
Re_outlet...Resistance of complete PE wiring.
Notes:
Resistance Re for distribution board (=Re_DB) is kept in the instrument memory
until new LOOP Re is done or the instrument initialized (see
4.4.5
).
CONTINUITY with LOOP Re sub-function operates only with the right connected
test connection.
F.2.3
IT modification - CONTINUITY LOOP Re
The procedure is intended for measurement the resistance of PE wiring between
distribution board and individual wall sockets. This is auto test only accessible procedure
consisting of two special functions: the
LOOP Re
and the
CONTINUITY
with
LOOP Re
sub-function
.
Test parameters for LOOP Re function
This function does not have any parameters.
