240 V AC/DC Proving Unit

The Fluke PRV240 is a portable proving unit that delivers a stable 240 V DC or 240 V AC reference output. It is designed for electricians and technicians who need to verify the operation of digital multimeters, clamp meters and voltage testers before starting live work.

Stable reference under continuous use

The unit maintains its rated output voltage during extended verification sessions without drifting under load. This behaviour ensures that each tester check reflects the true calibration state of the instrument rather than a momentary voltage sag.

Rugged housing with direct lead access

A durable enclosure protects the internal source circuitry from site knocks and dust. Recessed output terminals accept standard test leads securely, allowing quick daily checks without special adapters or fragile connections.

Questions about this item

How much heat does the PRV240 proving unit produce when it is running all day?

The unit is a portable voltage source without active cooling, so it generates only minimal warmth during normal use.

Which Fluke testers must I already own to use this 240 V proving unit?

It is designed for Fluke digital multimeters, clamp meters and voltage testers that accept a 240 V AC/DC source.

Will the 240 V output of this proving unit work with an older Fluke meter that has a lower voltage range?

The source delivers a fixed 240 V AC/DC; the connected meter must be rated for at least that voltage to verify safely.
