To allow displaying live operating parameters in the seven segment area
at the same time as user supplied data is shown in the dot matrix area of
the display, a weigh mode parameter (0P – 98P) can be displayed on the
seven-segment portion of the display.
In order to cause a weigh mode parameter to be continuously updated on
the numeric portion of the display, the instance specified for 90P must be
'12'. For example,
91.12P="0.0P"%o
The quotes are required, otherwise you will get only a static snapshot of
the parameter. The following are equivalent:
91.12P=0.0P%o
91.11P=0.0P%o
!
Note the missing quotes! It is also important to realize that adding
quotes has different effect for instances 11 & 12 of parameter 91.
