Tester can measure current and voltage without test leads

05 October, 2017

Fluke has developed an electrical tester which, it claims, can measure voltage and current without using test leads. It says that the T6 tester will allow users to troubleshoot electrical systems faster and more safely.

Troubleshooting electrical systems can be time-consuming and potentially dangerous, because it requires access to metallic contact points. The new testers, which incorporate a technology called FieldSense, allow users to take simultaneous voltage and current measurements – not just to detect their presence – without needing test leads.

The open-fork testers can take reliable true-rms measurements in crowded junction boxes or along conductors with inaccessible end-points, saving time, minimising potential errors, and reducing the possibility of arc flash.

They can:

•  measure voltages up to 1kV (using a model called the T6-1000), or 600V (with the T6-600 version), via an open fork without needing test leads or to access exposed conductors;

•  save time, by avoiding the need to open panels or to remove wire nuts;

Fluke's T6-1000 tester can measure voltages and currents without needing test leads. It can also measure resistance and frequencies.

•  measure and display voltage and current simultaneously on the T6-1000, or by toggling between readings on the T6-600.

•  measure wires up to 11.7mm in diameter, carrying currents of up to 200A.

The T6-1000 can also measure resistances up to 100kΩ, while the T6-600 can measure to 1kΩ. The T6-1000 can also measure frequency.

The rugged testers are 1kV Cat III, 600V Cat IV safety rated (600V Cat III for the T6-600 model), and include an easy-to-read display with a backlight.
