Three-phase rotation detection

The Fluke 9040 is a portable handheld instrument that detects the rotary field direction of three-phase systems. It uses three test leads to indicate clockwise or counterclockwise phase sequence on a digital LCD. The tester operates from 40 to 700 V AC across a frequency range of 15 to 400 Hz.

Industrial electricians and maintenance teams

This tool suits technicians who need to verify motor rotation or confirm supply phase order before connecting equipment. It is not intended for single-phase installations or for users who require insulation resistance, continuity or power quality measurements.

CAT III 600 V and CAT IV 300 V safety rating

The instrument carries a CAT III 600 V and CAT IV 300 V rating, defining the electrical environments where it can be safely used. This rating is the primary specification that determines whether the 9040 matches the installation category of the work site.

Questions about this item

What three-phase supply must I already have to use the 9040?

The 9040 works on three-phase systems from 40 to 700 V AC with a frequency between 15 and 400 Hz.

Will the 9040 still give a clear rotation reading if I keep my older CAT III 600 V or CAT IV 300 V test leads?

Yes, the 9040 is rated CAT III 600 V and CAT IV 300 V, so existing leads with those ratings remain compatible.

How do I confirm the 9040 is showing the correct phase sequence after I connect it?

The LCD displays a clockwise or counter-clockwise symbol to indicate the detected rotary field direction.
