6.3 RPE / RN / RL Measurement
To obtain precise measurement results,
switch off all loads or disconnect them from
the mains.
Connect the mains lead to the mains connec-
tor (13)
Select the measurement function via the fun-
ction switch (17).
Select the contact voltage by means of the
key “UL” (15) on the display.
The socket is continuously checked for perfect
functioning. If the symbol (6) "Reverse mains
plug” is displayed, the plug has to be turned or
the connection N and L of the three-pole test
lead have to be reversed. If the symbol for
“Socket Error” (5) is displayed, an internal
mains error exists. If the voltage between N
and PE exceeds the selected contact voltage
limit (50V/25V), "UB>UL" (3) is displayed.
By touching the contact electrode (16) the
contact voltage limit (chapter 6.6) may now
be tested. If the symbol "Socket Error " (5) is
displayed, a PE-error exists.
Press key “Start” (18).
Wait for approx. 5 seconds during this the dis-
play shows “-”.
Read the measurement result on the display.
By pressing the key “Display” (23) you may
now select between the different measure-
ment variables.
If a value exceeds the measurement limit, the
Attention symbol appears. If this result is sel-
ected with the key “Display“, the Attention
Symbol and “Limit” are displayed.
If the value RN exceeds the measurement
Limit, the outrun of RL is displayed too, be-
cause RN is necessary to get RL.
If the value for RPE shows 0,00
Ω
this could be
a Note of an exceeding interfering voltage.
If a contact voltage UB is generated between N
and PE during active measurement exceeding
the selected contact voltage limit UL, the mea-
surement is interrupted and the symbol
"UB>UL" (3) is displayed.
If a measurement has been interrupted due to
contact voltage limit UL excess, the symbol
"UB>UL" (3) disappears at the same time as the
mains plug has been disconnected from the
socket. During data saving, the UB>UL error
will be saved.
Also refer to chapter 7.0.
Possibility to store measurement results by
pressing the key „Store" (19).
If the defective condition of a socket has to be
saved, first press the key “Start” (18). After the
acoustic alarm signal the key "Store" (19) may
be pressed.´
