the internal signal is stable.
If these conditions are not met, an error message
is displayed.
The weight required for calibration/adjustment is displayed.

* “Calibration” technically means to determine the difference between
the scale readout and the actual weight on the pan to determine
the accuracy. Adjustment means to bring a scale into the state of accuracy
required for its use. Therefore, “calibration,” as used in this manual,
actually means “adjustment.”
