4.22. TRIM - TRIMMING ADJUSTMENT TEST
This test allows the operator to make adjustments to the transformer under test, at
selected points in the test program.
The TRIM test is inserted immediately following the test for the property that may
need to be adjusted. If the result for the previous test is a ‘PASS’, the trim test will
do nothing, and program execution will continue in the normal way. However, if the
previous test fails, the TRIM test calls up the Measure Mode for the previous test, and
lets the operator make the required adjustments to bring the parameter into
specification. Following the adjustments, the program must be re-run from the
beginning to produce a ‘PASS’ result for the transformer.
In a program, only tests from the following list are allowed to precede a Trim test:
R, LS, LP, QL, RLS, RLP, LL, C, LSB, or LPB
On selecting ‘TRIM - Trimming Adjustment’ from the Available Tests Window, the
following dialogue box will be displayed:
To program the test:
1. Select OK. The test will then be displayed in the program window.
