A 32-bit value,
Instrument Status
, provides the current state of all the major
functions within the
instrument. The top 8 bits are a cyclic “measurement
update count”, which will increment by a count of one every time a new
measurement value is taken, following a 0 to 255 then repeat cycle. If this
value remains the same in two consecutive reads from the instrument then
the communication or the measurement function has failed and the
appropriate action needs to be taken. The bottom 24-bits reflect the status
of all the major functions and should be used in conjunction with the
“measurement update count” to determine the health of the instrument.
The
Net
and
Gross Weight
values are always provided.
The final five read only command values
Parameter RD1 Value
,
Parameter RD2 Value
,
Parameter RD3 Value
,
Parameter RD4 Value
, and
Parameter RD5 Value
are the read
only values for the different user selectable parameter ID values set in the output table. If a
0x0000 is placed in the
Parameter RDx ID value
, or the requested parameter does not
exist a 0x0000 value will be returned.
