I am thinking about buying a Calcard Ext1 to save on the cost of having my Megger recalibrated every year.
But if I get one what documentation do I need to record the results?
I believe that I am supposed to test monthly and note down the results in some sort of log.
And what tolerance am I allowed for the month on month readings before the instrument is deemed to need recalibrating?
