The "User Offset Enabled" check box has the same function as before

Click on the ‘OK’ button. Again, the test and its parameters will appear
in the ‘Program’ window.
7. Finally, by double-clicking the left mouse button, select ‘TR Turns
Ratio’ from the ‘Available Tests’ window.
At the dialogue box, enter the data required for the turns ratio test:
Voltage 1V
Frequency 50Hz
Integration (Leave as the default - Medium)
The AT measures the turns ratio between ‘primary’ and ‘secondary’ windings;
and allows the possibility of applying the test voltage to a third ‘energized’
winding. For this example, the primary and energized windings are the same:
Energized high terminal A
Energized low terminal B
Primary high terminal A
Primary low terminal B
Secondary high terminal C
Secondary low terminal D
Using the default ‘ % ‘ type of limits, enter:
Primary: Secondary 1:1
Neg 2%
Pos 2%
