4.15.4.7. SETTING HESSEN PROTOCOL STATUS FLAGS
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:

NOTES:
It is possible to assign more than one flag to the same Hessen status bit. This allows the
grouping of similar flags, such as all temperature warnings, under the same status bit.
Be careful not to assign conflicting flags to the same bit as each status bit will be triggered if any
of the assigned flags is active.
