High-voltage probe for multimeters

The Fluke 80K-40 extends a multimeter’s range to 40,000 volts for low-energy measurements. It is built for technicians who need to verify high-voltage circuits without direct contact. The probe carries a CAT I 40000V safety rating and a one-year manufacturer warranty.

Thermal and electrical behaviour

The probe is rated for a maximum operating temperature of 122 degrees Fahrenheit. It draws no power of its own and adds negligible loading to the circuit under test. No forced-air cooling or active components are present, so acoustic noise is not a factor.

40 kV maximum voltage limit

The single specification that decides suitability is the 40,000 volt maximum rating. Measurements above this level require a different probe. The 14-inch length and high-voltage probe termination define the physical reach and connection style for the task.

Questions about this item

How do I connect the 14-inch Fluke 80K-40 probe to my multimeter, and what is the common mistake?

Attach the probe tip to the circuit under test and plug the banana connector into the meter's voltage input; the common mistake is forgetting to select the correct voltage range before applying 40000 V.

What part of the probe will need replacement after extended use?

The probe tip and internal resistor assembly can degrade after repeated high-voltage measurements and should be inspected or replaced if readings drift.

At what temperature does the probe reach its operating limit during sustained measurements?

The maximum operating temperature is 122 Degrees F; sustained use above this point can affect accuracy and safety.
