Holtgreven Doran All Purpose Washdown Scales - Manual (Page 8)

Scale reading is bouncing
or "flighty". Check for air currents and/or vibration around the scale. If
that is the cause it may be necessary to set the Digital
Averaging to a higher setting to stabilize the reading.
If you are still experiencing a problem with your scale, or if the problem you are having is
not covered in the above list, please contact your Doran Scales authorized dealer.
