NOTE:
-
If the sequence or the message format that the scale receives is incorrect, the scale responds with
NAK
.
-
The
„
X’
is a character which can take more than one value depending on weight status.
Space
(0x20): when the weight is correct.
'U'
(0x46) : when the weight is not valid or erroneous.
'
–'
(0x2D) : when the weight is negative (for example: Tare
weight without plate).
-
When the quantity in
absolute value is <1000 the leading zeros are fill with “0” (0x30h), but if the
quantity in absolute value is >=
1000 they are fill with “ “ (0x20h).
-
If the weight is erroneous (with “-------“ on the display) the scale replace the X and the weight by
FFFFFFF
. In the answer to the frame
D
2
, the amount is set 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 introduced price,
negative weight and amount to 0.
-
If the scale receives a frame with incorrect format, it 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 the adjustment of minimum weight, also concerns to
weight request.
