MTB7671/2

<p>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.</p> <p>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.</p> <p>The &#x27;Pass/Fail&#x27; 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 &#x27;Pass/Fail&#x27; indications. Additional test values are provided to ensure that the testers maintain consistent values across the range of their operating specifications.</p> <h3>Key features</h3><ul><li>Tests the full range of a testers capability</li><li>Does not trip RCD protected circuits</li><li>Tests to the regulations BS7671, BS EN 61557, and IEE On-Site Guide</li><li>Checks insulation, continuity, loop, PFC, RCD, and voltage measurement functions</li><li>Confirms testers continued performance between calibrations</li><li>Colour-coded test functions</li></ul>
