WARNING
This high voltage probe is designed to prevent accidental shock to the
operator when properly used. This operating note must be read and
understood prior to using the probe. Improper procedures or incorrect
analysis of the measurement situation can result in serious shock.
General Information
The Keysight 34136A High Voltage Probe is an accessory to be used with analog
or digital multimeters having an input resistance of 10 MΩ (±1%). The 34136A is a
1000:1 divider which extends a voltmeter’s measurement capability to 28 kV rms
ac (DC+AC p-p 40 kV).
Specifications
Maximum input voltage
DC voltage: 28 kV rms ac (DC+AC p-p 40 kV)
AC voltage: (0 to 300 Hz) 28 kV rms
Typical accuracy
DC voltage: ±2% (1 kV to 20 kV) ±3% (20 kV to
40 kV)
Pollution degree 2
Other Characteristics
Input resistance
1000 MΩ
Cable length
1 meter
Altitude
Up to 2000 meters (6561 ft)
Typical accuracy
AC voltage: 5% at 60 Hz
Temperature coefficient
Less than 200 ppm/ °C
Typical division ratio accuracy
1000:1 ±1% when terminated in 10 MΩ
2000:1 ±6% when terminated in 1 MΩ
Note: For the 34401A, 34405A, L4411A, 34410A/11A, and 3458A
multimeters, the ACV input impedance function has a 1 MΩ input
impedance.

Actual AC accuracy varies with the amount of shunted input capacitance.
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 effect the
safety of the measurement situation.
– It is advisable to 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
– Connect the plugs to the volts [Hi] and com [Lo] terminals of your voltmeter.
– Select the desired voltage function and range; do not use autoranging.
– Whenever possible, turn the high voltage source off before making any
connections.
– Connect the divider probe common lead (alligator clip) to a good earth ground
or reliable chassis ground.
Keysight 34136A User’s Guide 5
WARNING
– Do not attempt to take measurements from sources where the chassis or
return lead is not grounded.
– 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 voltmeter. 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.
– Do not connect the ground clip lead to the high voltage source for any
reason.
– Before turning the high voltage on, make sure that no part of your body is
in contact with the device under test.
– Measure the voltage remembering that the voltage being measured is
1000 times greater than the voltmeter reading.
– Turn the high voltage off.
– Disconnect the probe tip from the high voltage source BEFORE removing
the ground clip lead.
– This probe assembly is intended for use within measurement category I.
Do not use the probe assembly for measurements within the other
measurement categories or transient overvoltages greater than 1500 V.
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 be submerged at any time.
– Dry the probe thoroughly before attempting to make voltage measurements.
– Do not subject the probe to solvents or solvent fumes as these can cause
deterioration of the probe body and cables.
