Open-fork electrical tester

The Fluke T6-600 is a handheld digital multimeter that uses FieldSense technology to measure AC voltage and current through an open fork without contacting live conductors. It accepts wires up to AWG 4/0 with a 17.8 mm jaw opening and includes a backlit display for clear readings in low light. The tester is rated for 600 V CAT III environments and comes with integrated test leads for additional measurement modes.

Sustained-load behaviour

FieldSense technology enables continuous AC voltage measurement up to 600 V and AC current measurement up to 200 A using only the open fork, eliminating the need to break circuits or strip insulation. The 17.8 mm fork maintains consistent coupling on conductors up to 120 mm² during extended monitoring sessions. True RMS sensing ensures accurate readings on non-linear loads throughout the measurement period.

Deciding specification

The 600 V AC/DC voltage range combined with 200 A current capability through the open fork determines whether this tester covers the circuits you work on daily. Buyers who need voltage measurement above 600 V or current measurement beyond 200 A cannot use this model for those tasks. The 17.8 mm jaw opening also limits use to conductors no larger than AWG 4/0.

Questions about this item

How much heat or noise does the T6-600 produce during all-day use?

The T6-600 is a handheld electrical tester with no fan or moving parts, so it generates no audible noise and negligible heat during continuous operation.

What must I already own to measure AC voltage with the 17.8 mm fork?

Nothing extra is required; the open fork uses FieldSense technology to measure AC voltage up to 600 V and AC current up to 200 A without test leads touching live conductors.

Will the 17.8 mm jaw fit the AWG 4/0 cables in my older panel?

Yes, the 17.8 mm jaw opening accepts wires up to AWG 4/0 (120 mm²), covering the large conductors typically found in existing installations.
