Carrying out Measurements

If the RN conductor resistance exceeds
19.99

, the measurement is interrupted. The

message "Attention (1) + Limit (2) + RN" is dis-
played.

If the RPE resistance of PE conductor exceeds
1999

, the message "Attention (1) + Limit (2)

+ RN" is displayed.

If a contact voltage UB is generated between N
and PE during the active measurement and ex-
ceeding the selected contact voltage limit UL,
the measurement is interrupted and the sym-
bol "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 and connected to a socket in perfect
working condition. During data saving, the
UB>UL error will be saved.

Please also refer to Chapter 7.0

Option to save measurement results 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.

6.2   Internal Mains Resistance Measurement

Short-Circuit Current Measurement

To obtain precise measurement results, switch
off all loads or disconnect them from the mains.

Connect the mains lead to the mains connector
(13) 

Select measurement function via the function
switch (17).

Select contact voltage limit by means of the key
“VC / UL”  (15) in display.

The socket is continuously monitored for per-
fect functioning. If the symbol (6) "reverse
mains plug” is displayed, the plug has to be tur-
ned or the connection N and L of the three-pole
test lead have to be reversed. If the symbol
“Socket Error” (5) is displayed, an internal
mains error exists. If the voltage between N and
PE exceeds the selected (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 dis-
played, a PE-error exists.

Press key “Start” (18).

Wait for approx. 3 seconds, during this the dis-
play shows “-”

Read the measurement result on the display.

By pressing the key “Display” (23) you may now
select the different measurement variables (RI /
IPSC)

If the internal resistance exceeds 19.99 

, the

message "Attention (1) + Limit (2) " is display-
ed.

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.
