My results are not what I expected

  • Check the most recent scale calibration.  If it has been longer than a year, get it recalibrated
  • Check the most recent lift test; if it is lower than -3 (say, -2.5), clean the top of the unit to see if the situation improves
  • Check to see if the ceramic tubes are touching the sides.  When they rub, they cause the weight to appear to be jumping around and/or going backwards
  • Verify the time and date on the scale.  If you see ‘--:--’ it means that the information has been lost and needs to be reset.
  • If possible, verify that the scale is reading correctly.  If you have a known weight, this can be used.  Otherwise, compare against an external scale
