Safety precautions
This high voltage probe must only be used by personnel who are trained, experienced, or otherwise
qualified to recognize hazardous situations and who are trained in the safety precautions that are
necessary to avoid possible injury when using such a device.
Do not work alone when working with high voltage circuits.
For your own safety, inspect the probes for cracks and frayed or broken leads before each use. If defects
are noted, DO NOT use the probe.
Hands, shoes, floor, and work bench must be dry. Avoid making measurements under humid, damp, or
other environmental conditions that might affect the safety of the measurement situation.
If possible, always turn the high voltage source off before connecting or disconnecting the probe.
The probe body should be kept clean and free of any conductive contamination. Refer to the section on
cleaning.
Operation
1.
Connect the plugs to the volts (HI) and corn (LO) input terminals of your voltmeter.
2.
Select the desired voltmeter function and range: do not use autoranging.
3.
Whenever possible, turn the high voltage source off before making any connections.
4.
Connect the divider probe common lead (alligator clip) to a good earth ground or reliable chassis
ground.
WARNING
Do not attempt to take measurements from sources where the
chassis or return lead is not grounded.
