13. Check all connections to ensure correctness
14. Hit Blue Play button to begin test.
The saturation will begin. X Voltage (V): The MVCT displays the real time voltage readings of the
secondary X winding while the test is in progress.
X Current (A): The MVCT the real time current readings for the secondary X winding while the
test is in progress.
Saturation Curve: The excitation curve is Log-Log curve with secondary current on X coordinate
and secondary voltage on Y coordinate. Saturation curves for all correlating taps will be graphed
in the chart in the right hand corner of the screen in real time as data is accumulated.
15. At any point of time Test can be terminated by hitting the ABORT button at the top
of the screen.

16. Upon completion of test the results will be displayed in the test screen or it can be displayed
in a test report by selecting the view report button
17. Saturation points: The unit automatically determines the knee point based upon the
user selected standard (ANSI 30, ANSI 45 or IEC 60044-1). Saturation voltage and
saturation current corresponding to that knee point are displayed along with other
results at the completion of the test.
