Take this calibration box with you wherever you go to check the ongoing accuracy of insulation, continuity, loop and RCD testers.

Built inside its own protective carrying case, the MTB7671 ensures that your tester remains accurate and within specifications during the time period between official calibration procedures. This makes sure that your tester operates safely and doesn't generate inaccurate results (ensures compliance with such bodies as the NICEIC, ELECSA and Corgi).

Capable of checking the full range of a tester's capability and even includes colour coded sections for easy identification of testing procedures and clearly indicates whether the connected tester has passed or failed the test.

The MTB7671 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. There are also self-adhesive test labels for your tester.

• Tests the full range of a tester's capabilities to ensure measurement accuracy is maintained.

•  Designed not to trip RCD-protected circuits.

• RCD testing - 10mA, 30mA and 100mA testing values. 

• Tests in line with BS7671, BS EN 61557 and IET On-Site Guide regulations.

• Checks insulation, continuity, loop, PFC and RCD functions.

• Confirms testers continued performance between calibrations.

• Colour coded test functions.

• Built inside its own protective hard transportation case.

• Insulation testing - verifies voltage and current for 250V, 500V and 1kV voltage points plus additional 9MΩ and 90MΩ test values.

• Continuity testing - verifies that the correct open circuit voltage (4-24V) and short circuit current (>200mA) are present. 0.5Ω and 5Ω test values also included for resistance measurements.

• Loop testing - provides direct loop measurement from outlet socket with trip or no-trip testing procedures.

• Voltage measurements - this tester can check the voltage measurement range of an instrument.
