You can display each of the analog input resources
available on the HMS1655 with one of two engineering units settings: imperial and
metric. The default engineering units setting is imperial.
Procedure
To change the units settings for a particular analog input, tap
Engineering Units on the System
Setup menu.
The four universal analog inputs and two thermistor inputs are shown as options
on the Engineering Units Setup menus. Select one of these options to open the
AI-x Engineering Units popup where you can select either imperial units or
metric units.
Note: The choice of engineering units available is dependent on how the
specific analog input was configured. For analog inputs configured for
differential pressure measurements, the available options for engineering
units include inches of water column and
pascals.
For an analog input configured to measure air flow using a velocity sensor,
the available engineering units are ft/min and
m/sec.
The two thermistor inputs measure temperature and are displayed in degrees
Fahrenheit or degrees
Celsius.
