The T100 analyzer is a single gas instrument that measures SO
ID has already been set to 110. There is no need to change this setting.
Teledyne API's implementation of Hessen protocols includes a set of status bits that the
instrument includes in responses to inform the host computer of its condition. Each bit
can be assigned to one operational and warning message flag. The default settings for
these bit/flags are listed in Table 6-7:
