Note: The maximum measurement time is three minutes. If
after three minutes there is still more than one element in the
analogue arc, the test will stop. More than one element shows
that the instrument has not achieved its desired con󰘰dence level
(electrical noise is high). The test is still valid, but with reduced
accuracy.
6. Press TEST at any time to stop the test. A digital test
result will show and the size of the analogue arc shows
the degree of con󰘰dence in the test result (smaller the
analogue arc = more con󰘰dence).
