Powercheck 1557
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 On-
site 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). PowerCheck tests for Full Earth Continuity, Insulation
Resistance, RCD Trip Time, RCD Trip Current, Loop, PE Conductor Current, Touch Current
and Flash test verification.
