Internal Mains Resistance Measurement - BEHA Unitest TELARIS SCHLEIFE Mode D'emploi

If the RN conductor resistance exceeds
19.99Ω, the measurement is interrupted. The
message "Attention (1) + Limit (2) + RN" is dis-
played.
If the RPE resistance of PE conductor exceeds
1999Ω, 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.
Carrying out Measurements
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 et 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 Ω, 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.
