MEGGER MTB7671 Calibration Checkbox

►  The only one that fully tests your instruments to the regs. 
►  Tests the full range of a testers capability
►  Does not trip RCD protected circuits
►  Checks insulation, continuity, loop, PFC and RCD functions of testers
►  Confirms testers continued performance between calibrations
►  Colour coded test functions
►  Works with all testers for Part P Certification

The Megger MTB7671 test box is designed to provide confirmation that your testers continue to operate properly, and maintain their accuracy and consistency between calibrations. Certification bodies like the NICEIC, ELECSA, CORGI and others now request evidence of your tester’s accuracy and consistency.  Tests to the regulations BS7671, BS EN 61557 and IEE On-Site Guide. The Megger MTB7671 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 4-24 V. The PASS/FAIL values are selected to ensure that where there is a published specification for a test parameter then the MTB7671 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.
The values chosen for MTB7671 test points are the same as those supplied on all new Megger test instrument calibration certificates which means that you can confirm that the tester continues to provide results that are
consistent with its original calibration points.

The MTB7671 calibration checker makes that an easy job. You can test the insulation resistance, continuity, earth loop impedance, PFC, RCD and voltmeter functions of you testers quickly and easily, recording the test results on the record cards included in the pack.

The test box is supplied with a pack of 10 history cards and “Passed” labels, which can be stored in the test box.
