Start measurement.
Switch ON the PRCD within 8 s when prompted on the display. Measurement can be
stopped manually or by timer.
Save results (optional).

Note:
Mains voltage is applied to the PRCD during the test.
L and N conductors are not
allowed to be crossed in this test. Reconnect the PRCD’s
plug after pre-test, if requested.

– Contact voltage
Warning!
MI 3325 checks voltage on RCD-PE before running test and disables test in case
the hazardous live voltage is detected. In this case, immediately remove supply
from tested circuit, find, and eliminate problem before any other activity! See
chapter
1.2 Testing potential on TP1-PE terminal for installation tests
