3.4.22 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.
