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;
• 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.
