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).
