The LFR is a dual range ac current probe with a flexible,clip-around coil. It can bepowered either by a single9V battery or an external dc supply.

　　The LFR has market leading low frequency performance,optimised to give minimal phase measurement error from 45Hz up to 20kHz and the lowest possible noise floor. lt also has a good high frequency performance e.g.1.0MHz bandwidth for a 300mm coil.

　　The LFR has a 10:1 switch selectable current rating to give a wide measurement range in a single probe.

　　lt is available in ratings from 60A up to 60.0kA and with coil lengths from 300 to 1000mm. Longer coils can be supplied on request.

　　The LFR is ideal for current monitoring in power measuring applications, of leakage currents, and for power quality measurements.

　　The LFR is a Rogowski current probe with all the benefits: easy to insert in confined spaces (8.5mm max coil thickness), not affected by dc current, is undamaged by current overloads and is non-intrusive.

The LFR can be used with oscilloscopes, power analysers and meters, acquisition cards and dataloggers.

　　The LFR is CE marked and complies with safety standard EN61010.
