Bad contacts are the main reason for unreliable reading on adapters. On Innosen’s Foil Enamel Rater, contacts are verified before every test. Because it’s semi-automatic, all the operator needs to do is to load the aluminium foil sheet and invert the pot. When used with a dedicated IS810 EnamelPro, the voltage drop in the cables is compensated for so that, irrespective of the current, 6.3 volts is always supplied. This leads to more accurate measurement and better repetition.
