Measurement Range
10k

to 10M
Ω
Where Used
The continuity test should be placed as the first test in the program to check
that a transformer has been inserted correctly into the test fixture. The test
checks that every winding has a resistance less than a user-specified limit,
with the same limit being applied to all windings.
The continuity test will be quicker to execute than a series of resistance tests
applied to each winding.
Used together with the ‘Stop on Fail’ option, CTY will allow you to re-insert a
transformer into the fixture without recording a ‘FAIL’ or wasting further test
time.
CTY is a production-oriented test and is not available in the ATi’s front panel
LCR meter mode.
Programming the Test Using the PC Test Editor
Choosing the Test Limit
When specifying the test limit, remember that the same limit is applied to each
winding, so you must choose a value higher than the resistance of the biggest
winding. For most transformers, where the winding resistances are less than
1k
Ω
, a test limit of 10k
Ω
should be used, as this will give the quickest test
execution.
