Measuring Rcd Tripping Current - Beha-Amprobe Telaris Série Guide D'utilisation

To measure RCD tripping time using Auto mode:
1. Plug the tester into the outlet.
2. Turn the rotary switch to the
3. Press F1 to select the RCD current rating (10, 30, or 100 mA).
4. Press F2 to select Auto mode.
5. Press F3 to select the RCD test-current waveform.
6. Press and release
The tester supplies ½x the rated RCD current for 310 or 510 ms (2 seconds 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.
7. Reset the RCD.
8. The tester reverses phases and repeats the 1x test. The RCD should trip and the test
results appear in the primary display.
9. Reset the RCD.
10. 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.
12. The tester reverses phase and repeats the 5x test. The RCD should trip and the test
results appear in the primary display.
13. Reset the RCD.
• You can use the
last measurement taken, the 5x current test. Press the down arrow ke
backward to the first test at ½x the rated current.
14. Test results are in temporary memory. If you want to store the test results, press
and proceed as described in "Storing and Recalling Measurements" on page
37 of this manual.
Note: You must store each result separately after you select it with the arrow keys.
