Fluke T6-600 clamp meter

Measure voltage … without test leads
Working in cramped electrical boxes and trying to find a safe metallic contact points is often challenging. The Fluke T6-600 Electrical Tester with FieldSense™ technology, lets you quickly and safely take measurements by sliding the open fork over a conductor, without the need for test leads. The T6-600 works with wires up to AWG 4/0 (120 mm2) with a 17.8 mm jaw opening

How FieldSense™ technology works
FieldSense™ technology is a breakthrough in how voltage is measured. Other open fork testers detect a magnetic field to show AC current. FieldSense™ technology detects an electrical field, which interacts with a reference signal created by the T6 tester, which shows the measurement value on the tester’s display.

Tips on using FieldSense technology

Do not hold or touch wire you are testing during a measurement.
Use the black probe to make the ground connection if you are wearing gloves, insulated footwear or standing on an insulated ladder
Measurement versatility
The electrical tester offers a variety of measurement options giving you an all-in-one troubleshooting tool. Measure true rms voltage and current from 0 to 200 A AC or 1 to 600 V AC or DC. You can also gather resistance measurement from 1 Ω to 2000 Ω. With the easy-to-read backlit display, you can keep see your work in dark environments and keep your most recent measurement on the screen with the HOLD button for easy viewing. The T6-600 also accepts optional Fluke TPAK Magnetic Meter Hanger for convenient operation.
