High Voltage Probe HV-P60A
Read the following safety information
Warnings
●Measure in accordance with operating procedure when using
this instrument.
Erroneous operating procedure (refer to “3. Adjustment of Probe” and “4.
Measuring method”.) may result in an electric shock, fire or malfunction.
●When connecting the object to be measured to the nose of the
probe, firmly fix a measuring lead with an accessory Clamp.
Imcomplete clamping may result in an electric shock, fire or malfunction.
●Do not bring a grouding lead into contact with an insulator or
the nose of the probe.
If the grouding lead is brought into contact with the insulator or nose of the
probe, it may result in an electric shock, fire or malfunction.
●Coating of the grouding lead is voltage resistant (approx. 10
kV, but a clip is not and should be used carefully.
●Do not apply a voltage higher than the specified one.
If a voltage higher than the specified is applied, it may result in an electric
shock, fire or malfunction. The maximum input voltage is 60 kV at DC to 20
kHz. If the frequency exceeds 20 kHz, the maximum input voltage will
decrease (see “Fig.7 Maximum Input Voltage vs. Frequency”).
●During or before measurement, make sure that no one or
nothing come into contact around you.
If you touch someone or something during measurement, it may result in an
electric shock.

Read the following safety information
Warnings
●Do not use in an environment with explosive gases.
It may cause an explosion.
●If you notice smoke, foul odor or abnormal noise, stop
measurement immediately.
Continued use under these circumstances may result in electric shock, fire
or malfunction. Immediatelly, turn off the power switch of the object to be
measured and remove this probe from the object to be measured after
confirming the thing that a high voltage has not gone out, and contact
Iwatsu office or our sales distributors for repair. The customer should never
repair the instrument because it is dangerous.
●This instrument is not a waterproof. Make sure no water gets
on or inside the instrument.
If the instrument is used in the wet condition, it may cause an electric
shock, fire or malfunction. If water is allowed in it, immediately turn off the
power switch of the object to be measured and remove this probe from the
object to be measured after confirming the thing that a high voltage has not
gone out, and contact Iwatsu office or our sales distributors for repair.
●Do not use this instrument when the drop of water adheres to
it or the hand is wet.
Otherwise electric shock, fire or malfunction could result.
●Do not place this instrument on an unstable place, such as a
shaky stand or an inclined place.
If this instrument is placed on an unstable place, it may be fallen down or
laid down, causing a personal injury or malfunction. It is recommended to
use a probe stand SK-301 (option). If this instrument is fallen down or
damaged, immediately turn off the power switch of the object to be
measured and remove this probe from the object to be measured after
confirming the thing that a high voltage has not gone out, and contact
Iwatsu office or our sales distributors for repair.

Read the following safety information
Warnings
●Connect the playground of the probe body with the grounding
potential (playground) of the object to be measured.
When the playground of the probe body is connected with potential other
than the playground of the object to be measured, it might cause an
electric shock or malfunction (for the object to be measured, this
instrument, and connected oscilloscope).
●When thunder begins, pull out the power plug of the target or
the oscilloscope to which this instrument is connected from
the outlet. Then, detach this instrument from the oscilloscope
or the object to be measured, and do not use it.
If not, lightning may cause an electric shock, fire, or malfunction.
●When the insulator is contaminated, wipe off contamination
prior to using it.
If the insulator is contaminated, a high voltage may leak and cause an
electric shock, fire or malfunction. Apply a little amount of neutral detergent
to soft cloth and wipe the insulator gently with it. Do not use highly volatile
liquid such as benzene or thinner.

malfunction.
●Do not put this instrument in a place exposed to lamp soot or steam
generated by counters, humidifiers, etc.
It may cause fire or malfunction.
●For your safety, remove the oscilloscope and the target to be measured
from this instrument before maintenance. In addition, wipe off with a dry
cloth when water droplets are attached.
If not, an electric shock or malfunction may occur.
●Before transporting this instrument, pack the housed instrument in the
packing material used at the time of purchase, or the equivalent or
better.
This instrument may fail if a large vibration or impact is applied during
transportation, possibly causing an electric shock or fire. If you do not have
a proper packing or shock-absorbing material for transportation, contact
Iwatsu office or our sales distributors. If transportation is to be handled by a
forwarding agent, display "Contains a precision machine" on each side of
the packing box.
●We recommend that you contact Iwatsu office or our sales distributors
for periodic inspection and calibration about once a year.
The measuring instrument might grow by the secular distortion the error
margin of measurements, and not fill a prescribed performance.
(The check and the calibration are received for a fee.)

3. Adjustment of Probe
A waveform adjustment is necessary for this probe. A waveform
adjustment of this probe adjusts the capacity of the variable capacitor
that exists in this probe as the gain steadies for the frequency when
the oscilloscope is combined with this probe. If this adjustment is not
appropriately done, a correct measurement cannot be done.
Adjust the waveform of this probe when this probe is connected and
used for the oscilloscope.
The waveform of this probe is adjusted with the following
preparations according to the procedure.
3.1 Preparations
Prepare the signal generator that can generate the following signal
specifications and the measuring instrument (oscilloscope) used for
the measurement thereafter.
As for the example of the used equipment, it is not the following.
