Figure 4 23: Example of loop impedance measurement results
Displayed results:
Z
Fault loop impedance
ISC
Prospective fault current (displayed in amps)
Notes:
•
The specified accuracy of test parameters is valid only if mains voltage is stable during the
measurement.
•
The Fault loop impedance measurement trips RCD protected circuits.
4.4.2 The fault loop impedance test for RCD protected circuits
How to perform RCD trip-lock measurement
Step 1
Select the LOOP function with the function selector FCT key and select the
LOOP
mode with the
▲▼
and
◀▶
navigation keys. Then select desired
Type, Time and Curr
option values with the
▲▼
and
◀▶
navigation keys. The following menu is displayed:

Step 2
Connect the appropriate test leads to the instrument and follow the connection diagram
shown in figure 4.12 to perform RCD trip-lock measurement (see chapter 4.3.1 Contact
voltage).
