Calibration Checkboxes

Powercheck 1557 PAT and Installation Verification Instrument A comprehensive PAT and Installation instrument verification system in one rugged, drop-proof enclosure. It allows on-going performance checks to be carried out on test equipment to ensure accurate measurement between calibration intervals Tests verified: Earth Continuity, Insulation Resistance, RCD Trip Time, RCD Trip Current, Loop, PE Conductor Current, Touch Current and Flash tests Verifies earth continuity or earth bond testers up to 25A Does not trip RCD circuits Tests to BS 7671, BS EN 61557, IET Onsite Guide and IEE Code of Practice Confirms performance between verifications as required by NICEIC, ELECSA, Corgi and others NICEIC & IET compliant Colour coded controls for ease of use Compatible with all electrical installation and PAT testers

Megger MTB7671 Test Box Test box designed to provide confirmation that electrical installation testers continue to operate properly, and maintain their accuracy and consistency between calibrations. Tests the full range of a testers capability. Does not trip RCD protected circuits. Tests to regulations BS7671, BS EN61557 & IEE On-Site Guide. Checks insulation, continuity, loop, PFC & RCD functions. The test box is protected by a 30 mA RCD to ensure any faulty testers cannot cause an unsafe situation. Check of any voltage measurement ranges on the instrument. Colour coded test functions. Meets the safety requirements of IEC61010. Dimensions: 320 x 280 x 100mm. Weight: 2.2kg. Continuity short circuit test current 200 mA Pass / fail indication Continuity test voltage range 4V - 24V Pass / fail indication Continuity resistance 0.5Ω, 5.0Ω Insulation test current 1 mA Pass / fail indication Insulation test voltages 250V +25% max 500V +25% max 1kV +25% max Pass / fail Indication Insulation test resistances 0.25MΩ 0.5MΩ 1MΩ 9MΩ 90MΩ Loop Local mains impedance Loop + 1 Loop + 1Ω Loop + 180 Loop + 180Ω RCD currents (I) 10mA, 30mA and 100mA RCD no trip (1/2I) >1999 ms RCD (I) 40 ms @ 0° ; 50 ms @180° RCD (5 x I) 10 ms @ 0° ; 20 ms @ 180° Note Additional history cards & test labels are available see stock no. 480-302 Supplied with 10 history cards and 160 “Instrument tested” labels, manual & Calibration Certificate produced and dated at time of manufacture.
