VOLTECH AT3600 USER MANUAL CREATING THE PROGRAM

When the measurements have finished, the display will return to the dialogue box for
the LS test, with values entered for the test signal, the frequency and the nominal
inductance:
From this point, it is very easy for you to complete the dialogue box by simply
entering the values you require for the Negative and Positive percentage limits.
If you have chosen fixed voltage, current or frequency conditions it may not be
possible for the tester to make a measurement. For example, if the AC impedance of
the winding under test is only 0.1Ω at the specified frequency and you have specified
a 5V test signal, then the AT would have to supply 5V / 0.1Ω = 50 Amps!
You will then see a warning similar to this:
Check first that the winding is properly connected to the right nodes.
Choose ‘Yes’ and the AT will choose suitable voltage conditions for you and enter
them into the test dialogue. Choose ‘No’ and no conditions will be chosen. See
Chapter 7 – Tests and test conditions for suitable values.
