only an instrument that performs a full test according to the specifications

Test the functions of all your instruments, not just simple functions

Does not trip the RCD protection circuit

Meet the Part P certification test

The Megger MTB7671 Instrument test box is manufactured by a UK test instrument manufacturer, so your tester will be tested to UK standards.

No one understands the requirements and intentions of the standard better than Megger, so there's no need to waste your money on a poor product.

If certification bodies such as NICEIC, ELECSA, and others require proof of your tester's accuracy and compatibility, MTB7671 will make it a snap.

You can quickly and easily test the edge resistance, continuity, ground loop impedance, PFC, RCD, and voltmeter functions of your tester. The test results will be recorded on a recording card in the box. There are also self-adhesive test labels to attach to the tester.
