Take this calibration box with you to check the ongoing accuracy of insulation, continuity, loop and RCD testers.
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 Megger 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 (plus ensures compliance with such bodies as the NICEIC, ELECSA and Corgi).
The instrument is 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.
Tests the full range of a tester's capabilities to ensure measurement accuracy is maintained
Designed not to trip RCD-protected circuits
Tests in line with BS7671, BS EN 61557 and IET On-Site Guide regulations
Suitable for use with insulation, continuity, loop and RCD testers
Colour-coded interior for easy testing
Built inside its own protective hard transportation case
Insulation testing - the MTB7671 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
RCD testing - 10ma, 30mA and 100mA testing values
Voltage measurements - this tester can check the voltage measurement range of an instrument
