Using the Probe
Connect the probe to the BNC input of
the oscilloscope.
On the oscilloscope, select the desired
volts/division range. Whenever
available, set the probe attenuation
ratio setting to 100:1.
WARNING If possible, always turn the
high voltage source off before
connecting or disconnecting the probe.
WARNING Connect the probe
grounding lead (via alligator clip) to a
good earth ground or reliable chassis
ground.
For the best frequency response,
when measuring frequencies > 40
MHz use only the Main Grounding
Lead plus the Grounding Alligator Clip.
(Figure 1). For frequencies < 40 MHz
the Grounding Lead Extension Cable
may be used and will give you better
reach with the probe.
WARNING Before turning on the high
voltage source, be certain the operator
is not touching any part of the device
under test.
Turn on the high voltage source.
You will now be able to analyze the
voltage waveform on your
oscilloscope.
Turn off the high voltage source.
