INNOVATIVE ELECTRICAL METER VERIFICATION The CalCard fulfils the verification requirements for continuity and insulation instruments. All professionals working in the electrical environment have to test and verify their installations as both safe and correct. This is achieved by measuring the insulation and continuity of the installation using calibrated and accurate instruments. The accuracy and serviceability of the instrument when returned from periodic calibration will state it was within calibration parameters; but only at that time only. it certainly could not guarantee that the instrument or its leads and probes would still be fit for purpose at any time after that.

The CalCard satisfies fully the ongoing accuracy requirements. It is accepted and recommended by all inspectorates and regulatory bodies including NICEIC, ECA, NAPIT and ELECSA. The multiple industry award-winning CalCard is the smallest, most cost effective and versatile resistance checkbox available. The CalCard is used by over 30,000 electrical professionals each month.
