Fluke 9040 Phase Rotation Tester
The Fluke 9040 is used to check the phase rotation in a three-phase system. When working with motors, switchboards, or other three-phase equipment, it is important to ensure that the phases are in the correct sequence so that the equipment operates in the right direction. This handheld instrument displays all three phases and clearly indicates the rotation direction on the screen.
This is particularly relevant during commissioning, troubleshooting, and servicing, where one quickly needs to ensure that the connection is correct before proceeding. The instrument itself draws power from the system being tested, making it ready for practical use. It comes with three self-retaining test probes and an alligator clip, allowing for direct connection at the points of work.
The Fluke 9040 is rated for measurements in the range of 40–700 V and 15–400 Hz, and it is specified with safety categories CAT III 600 V and CAT IV 300 V. This makes it suitable for work in electrical installations where both an overview and safe handling are required. Its compact size makes it easy to carry in a service kit.
