User Calibration
In case the scale loses its accuracy, then the re-calibration of the scale
may be needed. The load cell of this precision scale is normally
protected against overloaded weight applied slowly, but extreme
overload caused by dropping the scale or dropping something heavy on
the scale may require re-calibration.
CAUTION: Please do not attempt any calibration by yourself unless you
have a 5 lbs weight available. Otherwise the scale will render itself into a
useless state and requires servicing.
