Megger LTW335 Loop Tester
Includes: Megger LTW335 Earth Loop Tester, BS1363 to 3 x 4mm Socket Leadset, 2 Wire Leadset with Croc Clips, Schuko Plug Test Lead - EU-SC, AU/NZ Plug Test Lead - EU-AU, Hard Carry Case and User CD.
The Megger LTW335 is three-phase safe and category IV 300V rated, making it suitable for use on supplies from 50V to 300V AC single phase, as well as on 440V three-phase installations.
Megger Loop Impedance Testers use the latest digital processing techniques to separate the test signal from the fundamental frequency of the supply. This means the Megger LTW335 Loop Impedance Tester automatically averages a large number of results over the duration of the test. This enables non trip testing to be performed without DC injection, a technique which is, in any case, proving ineffective with electronic RCDs. The LTW335 includes facilities for storing and downloading test results.
