If I put a nug on it, it doesn't usually read it or it will and then a split second later it will go back to 0. I tried putting a dollar on it and it said 1.9 gs. Anyone know how to fix this?
Try a nickel, its easier to tell and should be 5g. If it's off try and weigh things backwards. By that I mean put item on, tare (zero) out, take item off, check weight. Edit: The best thing to do if all else fails is borrow a friends scale. Weigh out the same thing on both, find the difference between the two. At least then you know how far off your scale is, and you can account that into everything you weigh.
