Programming the Test Using the PC Test Editor
Using the Measure Button to Set Test Parameters
Select the integration period you require, enter the primary and secondary
terminals, then click on the ‘Measure’ button as explained in the Editor section
of this manual. The Editor will then enter the test signal and show the
measured turns ratio. Set percentage limits on this ratio and click ‘OK’ (you
may select a polarity test before clicking ‘OK’).
Using the Auto Button to Set Secondary Voltage
To do this you must know the primary inductance.
Select the test voltage and frequency for the primary from the table below and
enter them in the TRL dialogue box. Enter the turns ratio, then press the ‘Auto’
button next to the secondary voltage parameter, the tester will automatically
select the appropriate test voltage for the secondary winding when the
program is running.
