I purchased a new scale via EBay roughly a year ago. I don’t think I’ve been able to get an accurate measurement. I’ve gone through the calibration process a number of times. I’m hoping a member here is familiar with this specific make/model and may be able to tell if the calibration instructions that came with this unit may be missing a step or is incomplete. After conducting the calibration process, I place a quarter on the scale, but I’m not seeing the correct weight reading for a quarter.
