Probing Principles
WARNING.
Do not put more than one uninsulated conductor at a time in the probe jaws. An uninsulated conductor is any
conductor without insulation or without insulation rated for the voltage present on the conductor under test.
To supply additional bucking current:
1.
Place a second conductor that has a pure
DC component of known value in the probe
jaw with the conductor under test.
2.
Orient the second conductor so that the
bucking current
fl
ows in the opposite
direction of the DC
fl
ow in the conductor
under test.
3.
To determine measurement values, add
the value of the bucking current to the
displayed measurement.
NOTE.
Adding a second conductor to the probe increases the insertion impedance and reduces the upper bandwidth limit of the
probe. Winding multiple turns further increases the insertion impedance, further reducing the upper bandwidth limit.
