Operation
1
Connect the probe to the BNC input of the oscilloscope.
2
Select the desired volts/division range. (If you can set probe
attenuation on the oscilloscope, set it to 1000:1)
3
Whenever possible, turn the high voltage source off before
making any connections.
4
Connect the divider probe ground lead (alligator clip) to a good
earth ground or reliable chassis ground.
5
Connect the probe to the voltage source.
6
Before turning on the high voltage source, make sure that no
part of the person holding the probe is touching the device
under test. Once this is certain, turn on the high voltage source.
7
Measure the voltage under test and observe the waveform on
the oscilloscope. Remember the actual voltage is 1000 times
greater than the oscilloscope waveform if the probe attenuation
on the oscilloscope has been set to 1:1.
8
Turn off the high voltage source.
9
Disconnect the Keysight N2771B High Voltage Probe from the
high voltage source BEFORE disconnecting the ground clip
lead.
WARNING
Do not attempt to take measurements from sources where the
chassis or return lead is not grounded.
WARNING
The ground lead is critical to the safe operation of the probe. Failure
to make this connection when making high voltage measurements
may result in personal injury or damage to the probe or oscilloscope.
This connection must always be made BEFORE the probe tip comes
in contact with the high voltage and must not be removed until the
probe tip has been removed from the high voltage source.
WARNING
Do not connect the ground clip lead to the high voltage source for
any reason.
WARNING
Do not make any floating measurements with the Keysight N2771B
High Voltage probe.
