2-7 UNIT WEIGHT CALIBRATION
♦
Two methods of unit weight calibration are available depending on the scale
configuration they are either:-
1. Auto Calibration
⇒
if weight is over 10% of the last sampling value, the scale
will automatically re-calculate the unit weight.
Example:
Say the current unit weight is 2.5g. If the next batch of product of the same
type has a slightly different unit weight say 2.8g, then because the difference
between the to unit weights is greater than 10% the scale will average the two
values and set a new unit weight of 2.65g. If the difference in unit weights are
less than 10% then the unit weight is not re-calculated.
2. Manual Calibration
⇒
Press SMPL key to determine the unit weight.
♦
The Auto Unit Weight calibration is setting is a factory set option. If it is set to off
then the auto unit weight calculation is disabled.
