Hi!
I have for sale a brand new, boxed Megger LT7 loop tester, with leather carry case, all etc and certificates, instructions etc. I have had it stored for a few years, and forgot about it, changed jobs and never took it out of it's box. Was around a £300+ tester at the time.
The blurb........
Megger LT7 Digital Loop Tester
* 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 supplies from 50V to 263V
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. The LT7 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.
For all prospective fault current measurements simply select the dedicated switch position. The nominal 23A test current is applied and the results are displayed directly on the liquid crystal display.
Two liquid crystal "neons" monitor the voltage between phase and earth and between neutral and earth, and will “light up†if a voltage is detected. The LT7 will check that the mains supply voltage is within limits and will inhibit testing if the earth contact voltage would rise above 50V if the test were c o n t i n u e d .
The MEGGER® LT7 Digital Loop Tester is powered by four internal dry cells although the test current uses the mains supply voltage. It is therefore able to make measurements of phaseearth loop resistance via a standard mains plug, or of phase-earth or phaseneutral loop resistance using the two wire lead set. The two wire set may also be used to test bonded metalwork.
Cheers!
