4. Select (mouse click the button) Ratio (%), or Turns (#) limits.
Enter the required limits:
Ratio (%)
Enter the nominal Primary to Secondary ratio, together with the limits as
positive and negative percentage values.
Turns(#)
In turns mode, you may set upper and lower limits on the primary and
secondary windings. The transformer tester will then set limits on the
turns ratio which are equal to the sum of these two errors, e.g.:
Primary
100 turns ± 2 turns
secondary 100 turns ± 2 turns
the tester will set the following limits on the ratio:
upper limit =
104/100 lower limit = 96/100
If you wish to set limits on only one winding, you must enter zero (0) as the
limit for the other winding.
Note that the Measure button may be used here as outlined in section
14.5.9.
5. If required, the polarity of the test can be checked. Click on the expected
polarity of the transformer turns, otherwise disable the test by selecting ‘No
Test’.
6. Select OK. The test specification will be displayed in the program window
on the screen.
