Megger's new two-wire loop resistance testers are designed to measure the loop resistance of an electrical circuit under operating voltage, i.e. without having to turn off the power supply. The new LTW300 Series allows two-wire loop testing without triggering a 30 mA RCD and can be used over a wide voltage range.
Peculiarities • 2-wire loop test without tripping RCD • Operating voltage from 50V to 440V • 110V loop test with grounded midpoint • Safety category CAT IV • Automatic testing start • Resolution down to 0.001 ohm (LTW425)
The new LTW300 instruments are packed with features that make loop testing easier and safer.
