Each of the analog input resources available on the FMS-1650 may
be displayed using one of two engineering units settings: Imperial and
Metric. The default engineering units setting is Imperial.
To change the units settings for a particular analog input, select the
Engineering Units option from the System Setup menu. The four
universal analog inputs and two thermistor inputs are shown as options
on the Engineering Units Setup menus. Selecting one of these options
invokes the AI-x Engineering Units popup where the user may select
either the Imperial units or the metric units.
The choice of engineering units available will be entirely 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 as shown in Figure 69. For an analog input that has been
configured for measuring air flow using a velocity sensor, the available
engineering units are feet per minute and meters per second as shown
in Figure 68.
The two thermistor inputs are dedicated for measuring temperature
and may be displayed in degrees Fahrenheit or degrees Celsius. The
next section discusses the options available on the Passwords Setup
menu and the management of the security passwords for the FMS-
1650.
