The Megger LT300 High Current Loop Tester offers high current loop testing over a wide range of frequencies and supply voltages with simple, fast, two wire operation. It has a large clear display that aids visibility in poor conditions.
The high current loop test provides fast accurate and stable results with a resolution to 0.01 ½ on the 20 ½ range. Supply frequency is indicated upon connection to the supply. This will automatically set to the measured supply frequency either 16 Hz, 50/60 Hz or 400 Hz. Testing will commence automatically.
The instrument is housed in a rubber armoured case with a built-in cover to protect the display when not in use. The IP54 weatherproof rating provides excellent protection in adverse conditions.
