The PowerCheck 1557 is the only comprehensive PAT and Installation instrument verification system in one rugged, drop-proof enclosure.
It tests to BS 7671, BS EN 61557, IET Onsite Guide and IEE Code of Practice. It has full instrument verification against all relevant standards and confirms performance between verifications (this is information required by NICEIC, ELECSA, Corgi and others).
The PowerCheck 1557 tests for Full Earth Continuity, Insulation Resistance, RCD Trip Time, RCD Trip Current, Loop, PE Conductor Current, Touch Current and Flash test verification.
