HT Instruments SPEED 418 Meter for Global Earth Resistance and for RCD’s Test

RCD and Loop tester with internal memory.

SPEED418 is an innovative Loop/RCD tester designed to perform Global Earth Resistance test without RCDs' tripping directly on sockets and all RCDs' trip out time and trop out current tests with automatic and manual modes on electrical installations in compliance to recently standards (VDE0100, BS7671 etc..). Another important test concerning the Loop impedance measurements with high resolution (0.1mOhm) (with IMP57 optional accessory) is performed by Loop/RCD tester SPEED418. The Loop/RCD tester SPEED418 it's very easy to use and thanks to newest electronic function selector it have an extreme rugged structure for perfect using on field". The instrument permits, moreover, to start principal measures by using a special remote prove (PR400 optional accessory) particular useful to perform tests in very quickly mode.
