5.1.4.7. Setting Hessen Protocol Status Flags

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
160
Teledyne ML'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:
