The cores of HVx and Cx are not allowed to be shortened with
the shielded cable. Otherwise, it is impossible to sampling and to
measure.
2. N(Negative connection)
If the low-voltage measuring terminal or secondary port of
equipment under test is grounded directly, negative connection
should be adopted.
The red special high-voltage cable should be led out from the
HVx which is on the back of the instrument; the high-voltage core
should be connected with the high-voltage terminal of equipment
under test. The low-voltage terminal should be grounded (see
Figure 12). At this time, the input line of Cx is vacant.
The core of HVx is not allowed to be shortened with the
shielded cable. Otherwise, it is impossible to sampling and to
measure.
