To program the test:
1. Enter the value of voltage (or current) for the signal and the required
frequency of the test. (If in doubt, refer to Chapter 7 - ‘Test Conditions’,
which lists recommended test conditions.)
2. 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.
3. Enter the terminal names between which the impedance is to be
measured. See terminal selection.
4. Enter the phase limits.
For phase tests, the convention of the result returned by the AT depends on
the minimum limit requested. If this limit is >0 the result returned is between
0
0
and 360
0
. If the minimum limit is >-180
0
, the result returned is between –
180 0 and 180 0 , otherwise the result returned is between – 360 0 and 0 0 . This is
done to ensure continuity of results and ease of setting limits irrespective of
where the phasor diagram is being checked.
Note: The Measure button may be used here as outlined in section 14.5.9.
5. Select ‘OK’. The test specification will then be displayed in the program
window.
