FEATURE DESCRIPTION
Manufacturer Defines the manufacturer of the reference device. If DH Instruments is

references. An <Other> choice is also available. Use this choice to set up
reference devices other than DHI models. When <Other> is selected, a pop-up
appears for entry of the manufacturer name of the reference device. A remote
interface with
COMPASS is not supported for non- DHI flow references.
Model
(drop down
list selection)
Defines the model of the reference device. When the manufacturer is
DH Instruments , the drop down list choices include all of the DHI models which
COMPASS supports with remote communications; non- DHI models must be
entered manually.
