The Output, Mode and Error Trigger Level settings will be applied to the
selected Port, which includes Port1, Port2 or the Input.
The Output of Port1 or Port2 can be Oxygen or Temperature.
The Input is always Pressure and cannot be changed.
The Mode of Port1 and Port2 can be set to one of the following:
• Off: No input reading or output writing.
• Linear: High and low value that has been set to correspond to 4mA
and 20ma. Values between these two settings will be calculated
linearly. Values outside this range will initiate the error trigger level.
• Bilinear: High, mid and low value set to correspond to 4mA, 12mA
and 20mA respectively. This mode allows higher resolution in a
certain range. Refer to Figure 4–54 for an example.
