4.4 Fault loop impedance and prospective fault current

The loop impedance function has two sub-functions available:
LOOP IMPEDANCE sub-function performs a fast fault loop impedance measurement on supply
systems which do not contain RCD protection.
LOOP IMPEDANCE RCD trip-lock sub-function performs fault loop impedance measurement on
supply systems which are protected by RCDs

4.4.1 Fault loop impedance

How to perform fault loop impedance 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 test leads to the instrument and follow the connection diagram shown in
the figure 4.22 to perform fault loop impedance measurement.

Step 3 Check for any warnings displayed on the screen and check the online voltage/terminal
monitor before starting the measurement. If everything is ok and the
the TEST key. After performing the measurement, the test results will appear on the
display.
