3. Connect the supplied high voltage test lead (black) to the low
voltage side (GND side) of the measured object.
If the low voltage side (GND side) of the measured object is
unknown, see section 3.2.3, "Measured Object's Polarity
and Ground."
4. Insert the end of the supplied high voltage test lead (red) for a
sufficient length in the INPUT terminal of thr tester, and fix the
lead with the plastic screw.
5. Set the AC/DC switch in accordance with the output of the
measured object.
6. Connect the supplied high voltage test lead (red) to the high
voltage side of the measured object.
7. Check that the 149-10A and measured object are connected as
shown in Fig. 3.3.
8. Turn on the power of the measured object.
