Tester for installations with TT neutral earthing system and live 2P+E socket. With its compact format, the MX 531 can be used one-handed and its wrist strap makes it easy to transport. Itsrotary head makes it easy to use wherever the 2P+E socket is located and the backlit display ensures that it is easy to read. The measurement result remains displayed for 10 s. The backlighting has a second function as it changes colour: blue when the MX 531 is connected to the socket, red if the measurement does not comply, grey if all the results comply and the MX 531 is disconnected.
The MX 531 is an electrical socket tester which can be plugged into all socket configurations:
it checks that an electrical socket in a TT system is operating correctly,
it measures the voltage and displays the conductor connections on a single-phase 2P +E socket,
it automatically measures the earth resistance RE,
it performs a trip test on the 30 mA RCD.
In addition, depending on the results, pictograms are displayed to provide further confirmation concerning their conformity. This stand-alone instrument without batteries is recharged directly on the mains. Self-employed electricians and installers, maintenance technicians: the MX 531 is designed to simplify your job every day. It is delivered with a wrist strap and a carrying bag.
