use, some guidance is given in chapter 7 (Tests & Test Conditions) later in this
manual.
If you are using the Measure button to enter limit values, as described in the
section later in this chapter, you may also at the same time have the AT Series
Tester enter the recommended test parameter values.
To do this in the case of the LS test, you simply leave the Signal and
Frequency edit boxes empty at the time you click on the Measure button. If
you choose either the ‘mV’ or ‘V’ unit button before clicking the Measure
button, the test signal determined by the tester will be entered as a voltage;
alternatively if you choose the ‘mA’ units button before clicking the Measure
button, the test signal determined by the tester will be entered as a current.
Note that not all tests allow the test parameters to be chosen by the tester.
The programming details for each test in section 7 (Tests and Test Conditions)
of this chapter specify which tests allow the Measure button to enter the test
parameter values.

In the Quick Start Tutorial (chapter 2), it was stated that for the R - Winding
Resistance - test the limits could be entered in four different ways. The R test
is not unique in this respect. In fact, most tests have several ways in which the
limits may be entered, allowing you greater flexibility in configuring each test to
match your production testing requirements.
The four types of limits for the R- Winding Resistance test are:
% The limits are entered as positive and negative percentages about a
nominal value.
> < The limits are entered as minimum and maximum values.
> There is only a minimum limit.
< There is only a maximum limit.
