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

Displayed results:
Z Fault loop impedance

Prospective fault current
Notes:
• The measurement of fault loop impedance using trip-lock function does not normally trip an
RCD. However, if the trip limit may be exceeded as a result of leakage current flowing through
the PE protective conductor or a capacitive connection between L and PE conductors.
• The specified accuracy of test parameter is valid only if mains voltage is stable during the
measurement.
