What does your Funtana 40 weigh?
I weighed mine on Sartorius Digital computer controlled scale used in our body shop that is zero'd every couple of months, its purpose is mixing automotive paint formulas and is accurate from 0 to 25 lbs and reads to the 1/10 of a gram and is accurate to +/- .05 grams, I just wish it were off by about 8oz!! LOL
Not holding my breath tho...
