1. Verify the Power ON/OFF switch is OFF. Power the test set from a suitable source
of power (95-125 or 195-265 V50/60 Hz).
2. Connect the ground wing nut to a suitable ground.
3. Turn Power ON/OFF switch to ON.
4. After boot up, in the Home Screen put the MVCT in voltage transformer testing mode by selecting
the VT button.
5. Select the “Secondary Short Circuit Impedance” button In the VT section of the Home Screen. This
will activate the impedance test screen

WARNING
There is always the possibility of voltages being induced at the terminals of a test
specimen because of proximity to high voltage energized lines. A residual static voltage
charge may also be present at these terminals. Ground each terminal to be tested with a
safety ground stick, before making connections.
WARNING
The MVCT produces high voltages and currents during the performance of tests. DO NOT
TOUCH connector clips or test leads while the MVCT is performing a test.
