Hi Dennis - Long time no see. Mine is a model 82062, bought for $50 about 3 years ago. Accurate to within 2%, plenty close enough. I'm not sure if that model no. is the same item no. you mention, but no need from this end to spend more money than the basic model. Also doubles as a dandy troubleshooter for your auto battery and starter. Tom H.
