Megger MTB7671/2 Test Box for Validating Installation Testers

The MTB7671/2 instrument test box is designed to provide confirmation that your testers continue to operate properly, and maintain their accuracy and consistency between calibrations.
The NICEIC, ELECSA, and Corgi, among others, now request evidence that your testers comply with this. The MTB7671/2 checks not only the basic functions of the testers, but also that the correct test current or voltage is being used during the test. For example, a continuity test should not just give a result in ohms, but the short circuit test current should be greater than 200 mA and the open circuit voltage should be within the limits of 4 to 24 V.
The 'Pass/Fail' values are selected to ensure that, where there is a published specification for a test parameter, the MTB7671/2 will test your tester to ensure that it meets these specifications using a series of simple 'Pass/Fail' indications. Additional test values are provided to ensure that the testers maintain consistent values across the range of their operating specifications.
