7 CALIBRATION
All weighing scales come pre-calibrated from the factory. However the
scale may require re-calibration. Temperature changes, geographic gravity
variations, altitude changes and abuse are few reasons why a scale may
need recalibration. The scale can be calibrated using a known external
weight.
