Fluke T6 electrical testers

Fluke T6 electrical testers with FieldSense technology enable electricians to take simultaneous voltage and current measurements without metallic contact. 

Troubleshooting electrical systems has always required gaining access to metallic contact points so the test leads can make contact. And while non-contact AC current measurement has been available in the Fluke T5 Electrical Tester for a few years, only voltage detection was available as a form of non-contact voltage testing.

The FieldSense technology takes the open fork functionality of the T5 Electrical Tester and adds, for the first time, AC voltage measurements. Now electricians can take simultaneous voltage and current measurements, not just detection, without test leads.

Contacting electrical conductors with test leads or alligator clips requires metal-to-metal contact, which carries the potential for arc flash. Because the measurement tool and the voltage source under test are isolated, the person performing the test is safer from potential electrical shock. This is performed by means of galvanic isolation or separation, the principle that isolates functions of an electrical current to prevent current flow. FieldSense takes a measurement of voltage without voltage flowing through the meter. Instead, tools like the T6 sense an electromagnetic field in the open fork to make the measurement. Since the measurement is performed through the cable’s insulation, the user has reduced exposure to metallic conductors. T6 testers also decrease the potential for errors or making contact with the wrong conductor.
