Why do Professionals Require a CalCard?

All professionals working in the electrical environment must test and verify their installations as both safe and correct. Professionals achieve this by measuring the insulation and continuity of the installation using calibrated and accurate instruments.

The CalCard® provides the modern solution to Ongoing Calibration Verification (OCV) which used to be provided by the older Calibration Checkbox. It achieves this by verifying the serviceability and ongoing accuracy of an instrument, ensuring it still can make the same truthful resistance readings throughout the time between these formal calibrations period.

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.

IIn the UK, all industry regulatory, health and safety bodies required electricians to perform a monthly procedural test to verify instruments ongoing accuracy test, eventually it became an integral part of the compliance requirements for all electricians.
