a us nickel weighs 5.0 grams on the dot, so when that happened to me, to recalibrate it i used 20 nickels
tbailey Reviewed by tbailey on . Scale Problem So yeah I bust out little digital scale last night to weigh somethin out with a friend and when I turn the device on I get an error message. I haven't used the scale in a few weeks but other than that it is brand new and this is not a battery issue. I look in my manual to fix the error message and find out the problem is related to calibration and can be easily remedied through a series of steps. However, when I was going through the process of recalibration, I realize I need a 100 gram weight Rating: 5
