To program the test:
1. Enter the test voltage and frequency at which the test is to be carried out.
2. Select one of the following; AC Voltage, DC Voltage or Mean sense, RMS
scaled measurement by clicking on the relevant button.
3. Select the integration time required.
'Medium' is the default setting. 'Long' will give more stable readings (for
tighter limits) at the expense of an increased test time, and 'Short' will test
at the maximum speed, but may give a slightly noisier reading. See 7.3
Explanation of Integration.
4. Enter the terminal names for the Energized High and Low Terminals.
Click on the arrow to the right of the fill-in box, and you will be provided
with a choice of available terminals; double-click on the one required.
Similarly, enter the names for the Measured Terminals.
5. Set the voltage limits.
% Enter a nominal value and then the limits as negative and
positive percentage values.
>< Enter minimum and maximum values.
> Enter just a minimum value.
< Enter just a maximum value.
Note: The Measure button may be used here as outlined in section 14.5.9.
6. Polarity testing can be included in the test by selecting either positive or
negative radio buttons to test against. Here the polarity test will produce
either Pass or Fail results. Polarity testing is not possible if the source type
is 'Manual Source / Line Supply'. (For AC measurements, use the positive
polarity when the measured winding has the same phase as the energized
winding, use the negative polarity when they have opposite phases.)
7. Select OK. The test specification will be displayed in the program window
on the screen.
