C.A. MX 531 - TESTER FOR TT NEUTRAL SYSTEMS, 2P+T SOCKET UNDER VOLTAGE
Tester for electrical outlets - earth testing - RCD 30mA, 3 measurements in one practical device
Description
The MX 531 tester is a compact device that can be used with one hand and, thanks to the wrist strap, comfortably worn on the wrist.
The rotating head ensures maximum ease of use regardless of the position of the 2P+T socket to be tested, while the backlit display facilitates reading. The measurement result remains visible for 10 seconds.
The backlight has a second function and changes colour to visually indicate that:
‐ the device is connected to the socket (blue)
‐ the measurement is non-compliant (red),
‐ all results are compliant and the MX 531 device is disconnected (grey).
The MX 531 is a socket tester compatible with all types of sockets,
It verifies the correct operation of electrical sockets with the TT system.
It measures voltage and displays the conductor wiring on single-phase 2P+T sockets.
It automatically measures earth resistance RE.
It tests the operation of the 30 mA residual current device (RCD).
Depending on the result, the tester also displays various pictograms to provide further confirmation of compliance. Autonomous and battery-free, it recharges directly from the mains socket. The MX 531 has been specifically designed to simplify the daily tasks of electricians, installers and maintenance technicians.
The wrist strap and carrying case are included in the supply.
