Description

The Megger^® LT7 Digital Loop Tester is a small hand held instrument designed to accurately, reliably and easily measure loop resistances and prospective fault currents at socket outlets, distribution boards and light sockets. TheLT7 may also be used for testing earth bonding.

Two loop tests are available; the traditional high current test for circuits protected by fuses, and a low current test for taking measurements on circuits which are protected by residual current devices (RCDs). Measurements of phase-earth loop resistance and prospective earth fault current (PEFC) are made at socket outlets using the standard lead supplied. The included two wire lead set allows these measurements, also phase-neutral loop resistance and prospective short circuit current (PSCC), to be taken at locations such as distribution boards or lighting fittings where there is no socket outlet available.

Key Features

• Guaranteed not to trip RCD’s, even electronic ones (less than or equal to 30 mA)
• Tests Phase-Earth and Phase-Neutral supply loops
• Low current loop test does not trip RCDs
• Direct readout of Prospective Short Circuit Current and Prospective Earth Fault Current
• Makes measurements on 110 V and 230 V supplies
