I bought a 0.01 gm scale here on auction for $40.00. I checked it with calibration weights I have from my diamond scales which weight to an accuracy of 0.005 of a gram. The scale was off by 0.01 of a gram at different points but mostly accurate. I then checked the stylus tracking force on my SME V on my Nottingham Hyperspace @ the platter lever (by removing the graphite top portion of the platter which is the approxamite thickness of the scale) and above the platter by placing the scale above the platter. At both planes the gram weight remained the same on the scale. Just my 2 cents. I don't know what it all means but once it sounds great it is amazing. Once it is out I just know it & keep on adjusting all my settings. Nothing like doing it by ear. The scale servers its purpose mainly when you switch between cartridges
