Starting of RCD Test
The current types and multiplication factors to
be selected at set nominal residual current are
listed in tables 1 and 2.
Select contact voltage using key "VC" (19).
Touch contact electrode PE (21).
Note display.
If the symbol "Socket Error" (4) is displayed, a
PE error or other socket error is present.
Press key "Start" (22).
After successful test the display key (32) is
used to switch between measurement result
tRCD and VC within the measurement value
display.
Display at trip time (tRCD)
Display at contact voltage (VC)
The measurement is interrupted if the contact
voltage exceeds the set contact voltage limit.
"Attention" (1) and "UB>UL" (3) appears on the
display.
Display at limit of contact voltage is exceed
If the RCD does not trip within correct tolerance va-
lues (also refer to table 3), the "Attention" symbol
(1) and "Limit" (2) are displayed besides measure-
ment value tRCD.
A possible reason could be:
•
incorrect selection of test current.
• a residual current is present within the net to be
tested, causing the RCD to trip early because it
sums up with the test currents.
• RCD faulty.
Display at trip time >300 ms
Measurement results may be saved pressing
key Store (25).
