Refer to the safety instructions first before use of the equipment.
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.

5.
Connect the test set primary binding posts H1 and H2 to either side of the CT burden. and H2.
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 MRCT produces high voltages and currents during the performance of tests. DO NOT
TOUCH connector clips or test leads while the MRCT is performing a test.
