Martindale LP2000 Loop Tester

The Martindale LP2000 Digital Loop Tester is a hand-held, mains powered instrument designed to measure the loop and prospective short circuit current (Ipsc) of electrical circuits in accordance with the 17th Edition of the IEE wiring regulations (BS EN 7671). It has a 3½ digit liquid crystal display and is available in various versions. The loop is measured over two ranges to 199.9Ω with auto range at 15Ω and with resolutions of 0.01 and 0.1Ω. The Ipsc is measured over one range of 19.99 kA with a resolution of 0.01kA. Three measurement modes, selected by the function switch, enable loop measurements to be made between the phase and earth conductor in the mains lead and prospective short circuit current measurements between the phase and neutral conductors in the mains lead. FEATURES: Test current of 24A, rms for two half cycles at 240V. Overvoltage CAT III rating. Suitable for use on 240V systems. Carries out P-E and P-N loop tests. Displays PSCC readings up to 19.99.
