The Fluke T6-1000 is the first-ever instrument of its kind. Thanks to Fluke's unique FieldSense technology, the T6 is capable of measuring voltage up to 1000V AC using only the meter's open fork. This means you don't need to open any covers or remove wire nuts to take voltage readings on AC sources. The meter's open fork jaw measures 17.8mm and is large enough to fit wires up to AWG 4/0. Plus, the T6-1000 can also measure current up to 200A AC through its open fork while simultaneously showing voltage and current readings on its backlit screen.
Important Specs
Thanks to FieldSense, you can use the T6-1000 to measure multiple electrical parameters through the meter's open jaw alone. FieldSense supports measurement of AC voltage up to 1000V, AC current up to 200A, and frequency from 45Hz - 66Hz (FieldSense frequency is only available on the T6-1000 model). You can measure all these parameters without test leads using only the meter's open jaw. That said, the T6-1000 does come with built-in test leads which allow you to measure AC and DC voltage up to 1000V, and resistance in multiple ranges including 2000Ω, 20.00kΩ and 100.0 kΩ.
It is important to note that in order to get the most from FieldSense Technology, the T6 meter must have a capacitive path to ground. In most applications, this is provided by the user via a ground contact on the rear of the meter. However, in some cases a ground connection must be made using one of the built-in test leads. FieldSense can only measure voltage relative to ground and must have a solid ground connection. Phase to phase measurement is not possible with FieldSense.
Measure Voltage Without Test Leads
Contacting electrical conductors with test leads or alligator clips requires metal-to-metal contact, which as any electrician or technician knows, carries the potential for arc flash. FieldSense eliminates that step. The person performing the test is safer from potential electrical shock because the measurement tool and the voltage source under test are isolated. This is performed by means of galvanic isolation or separation, the principle that isolates functions of an electrical current to prevent current flow.
