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 confidence 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 confidence in the test result (smaller the
analogue arc = more confidence).
