NOTE:
- The X can take the values:
o ' ' (0x20): when the weight is valid.
o 'F' (0x46): when the weight is erroneous or invalid.
o '–' (0x2D): when the weight is negative (for example: Tare without plate).
- The S can take the values:
o ‘S’ (0x53): when the weight is stable.
o ‘U’ (0x55): when the weight is unstable.
- If the weight is unstable momentary value is sent in the field WW.WWW. For the answer
D
2
, the price entered on the scale is sent and the amount is sent to 0.
- If the weight is erroneous (with "--------" on the display) the Scale replaces the X and the
weight by FFFFFFF. In the case of the D2 response frame, the price is the entered on the
Scale and the amount is displayed to zero.
- If the scale has a tare weight, it sends the net weight in the field WWWWW.
- If when the frame D
2
is sent the weight is negative, the scale responds with the price
entered on the scale and the amount to zero.
- If the scale receives a frame with an incorrect format, the scale responds with NAK.
- The scale takes into account the minimum weight adjustment. If this adjustment has the
value 1 the scale responds with NAK if the weight is lower than 20 steps.
- Between different requests the weight must vary at least 20 steps or pass through zero,
otherwise the scale responds with NAK.
- The minimum variation or zero crossing, and adjustment of minimum weight, also affect to
request frame of only weight
