T. If Auto Start is turned on (see Measurement Settings), the test starts
automatically as soon as the Tester detects the mains voltage and the required test leads
are connected.
The Tester supplies ½x the rated RCD current for 310 ms or 510 ms (2000 ms in the UK). If
the RCD trips, the test terminates. If the RCD does not trip, the Tester reverses phase and
repeats the test. The test terminates if the RCD Trips.
If the RCD does not trip, the Tester restores the initial phase setting and supplies 1x the
rated RCD current. The RCD should trip and the test results appear in the primary display.
9. Reset the RCD.
The Tester reverses phases and repeats the 1x test. The RCD should trip and the test
results appear in the primary display.
10. Reset the RCD.
The Tester restores the initial phase setting and supplies 5x the rated RCD current for up to
50 ms. The RCD should trip and the test results appear in the primary display.
11. Reset the RCD.
The Tester reverses phase and repeats the 5x test. The RCD should trip and the test results
appear in the primary display.
12. Reset the RCD.
The test results show in a table on the display. If the trip time meets the appropriate
standard of the RCD, the limit indicator shows. For more information, see the 1672/1673
FC/1674 FC Product Specifications at www.fluke.com
for the RCD Tripping Time table.
Note
Test results are in temporary memory.
