HVP-40M INSTRUCTION MANUAL
Safety Precautions
Thes e steps outline the minimum, basic safety
precautions that must be followed when using this high
voltage probe. Before you use this instrument, read and
thoroughly understand this information. You must have a
thorough understanding of the hazards that may occur
when working with high voltages and when using this
probe. Failure to follow good safety practices could cause
you serious personal harm, even death. Remember, high
voltage kills it safety precautions are not followed!
1. Examine probe, make sure it is clean and dry. Dirt,
moisture and grease can provide a creep path for
voltage. If in doubt, wipe with a clean, dry, lint-free
cloth.
2. Look at the condition of the floor in the test area. It must
be dry, clean and free of oil. Never stand on a wet or
damp floor.
3. Always connect the alligator clip of this probe to earth
ground before taking any measurements.
4. Examine the entry to your high voltage test point. Make
sure that you are able to bring the probe test point.
Also, make sure the tip is clear of wires, metal supports
and other nearby conductive surfaces.
5. Only use this probe to measure positive polarity DC
voltages.
6. Verify that you are able to remain clear and avoid
contact with any exposed metal and/or other
conductive parts of the device being checked.
7. Only use one hand to hold the handle of the probe.
Keep your free hand behind you, preferably in your hip
pocket. This position helps avoid a situation where the
voltage could flow across your chest should a mishap
occur. Current flow across your chest is very damaging
as it distrubs the rhythm of the heart.

8. Always work within sight and hearing of another
person. If an accident occurs, you will be able to get
aid quickly.
9. In addition to these safety instructions, follow those
given by the manufacturer of the device being
checked.
10. When handling a CRT, avoid touching the conductive
coating before it's discharged. Remember, it can hold a
dangerous charge long after the set is turned off.
This probe is a self-contained instrument; it measures
positive polarity DC high voltages up to 40KV. IT consists
of two interchangeable screw-in contact tips, a direct-
reading meter, ground clip and high-impact ABS case.
This case has excellent insulation properties, light-weight
and is resistant to damage.
One tip is a round needle type for general use; the other is
a special flat spring type for easy access to a CRT anode.
An alligator type clip lead provides a secure earth ground
connection.
A rugged, core magnet-type meter is supplied. It is
reasonably free from the effects of outside magnetic
fields and can withstand moderate shock and vibration
without damage.
The probe was factory calibrated at 25 KV. Under normal
conditions, it should not require periodic calibration.
This probe is typically used to measure high voltages in
TV sets, power supplies, laboratories and for general high
voltage commercial applications.
Description
Cleaning
Clean only the exterior probe body and cables. Use a soft
cotton cloth lightly moistened with a mild solution of
detergent and water. Do not allow any portion of the probe
to submerged at any time.
Dry the probe thoroughly before attempting to make
voltage measurement.
Do not subject the probe to solvents or solvent fumes as
these can cause deterioration of the probe body and
cables.
