waituntilthereadingstabilizes.Themoretheknownweightisclosertothefullscalevalue,themoreaccuratethefull
scalecalibrationwillbe.

The system is ready
to carry out the calibration with a known weight corresponding to the value of the weight
currentlyonthescale.
Theoperatorcanmodifytheprocedurebysettingdirectlytheknownweightvalue,usingkeys or
toincreaseordecreasethedisplayedvalue.
