Do YOU Confirm Your Instruments Calibration? The CalCard is a great way of keeping on top of the ongoing calibration checks required to electrical testers like the Megger MFT’s we use in the electrical workshop. The CalCard will help you confirm your multi function tester is performing correctly when measuring ohms and megohms readings scales used when carrying out continuity and insulation resistance. The card has fixed values of insulation resistance of 0.5MΩ, 1MΩ, 2MΩ, 10MΩ and 20MΩ, which ar
