0: READ PARAM CMD
. To read a parameter, write a #0 to the command register
(register #0), and write the parameter number in the parameter ID number in registers 2
and 3, most significant word first. The parameter value may then be read from registers
4 and 5, again most significant word first. This value may be in integer or floating point
format, depending on the parameter. The status register in the reply will contain the
lower 16 bits of the system status word.
•
Status word bit 0: A/D error
•
Status word bit 6 (0x40): Motion status.
•
Status word bit 15 (0x8000): Not Found - the requested parameter number does
not exist
•
1: ZERO CMD
. Write a #1 to the command register to ZERO the gross weight. The
status register will read 0 if this command succeeds.
•
Status Error code 1 (motion)
•
Status Error code 2 (A/D error)
•
Status Error code 3 (out of tolerance)
•
During a tare or zero command: Code 0xFFFF indicates "command in progress”
•
2: TARE CMD.
Write a #2 to the command register to ZERO the net weight. The status
register will read 0 if this command succeeds:
•
Status Error code 1 (motion)
•
Status Error code 2 (A/D error)
•
During a tare command: Code 0xFFFF indicates "command in progress".

command succeeds:
•
Calibration_Fail 1
•
Calibration_Fail_Motion 3
•
Calibration_Fail_Adc_Error 4
•
During a Cal Low Command,: Code 2 indicates "calibration in progress".

. Write a 0x65 hex to the command register to
perform the high step of a traditional calibration.
•
Calibration_Fail 1
•
Calibration_Fail_Motion 3
•
