Appendix Page 205
Example
A request with a command of 4 and a message field of 85,64,64,0,0 would place the instrument into
Span mode.
Set Calibration
Enters a new calibration value: the same as entering Span Calibrate or Zero Calibrate on the calibration
menu.
Where:
Command byte 18
Message byte 1 0, 1, 2, or 3 where
0 = Span
1 = Zero (first zero gas)
2 = Zero (second zero gas)
3 = Zero (Third zero gas)
Message byte 2 - 5 The IEEE representation of the calibration value.
A.3 List of Parameters
