Input Engineering Unit Conversion Example 1:
Data format = BCD,
Channel 1 data memory location = V2000,
Channel 1 resolution = 12 bits,
Channel 1 engineering units = 0.0–140.0 PSI,
Channel 1 input device = 0–5V or 0–10V transmitter.

Engineering Unit Conversion Example 2:
Data format = binary,
Channel 1 data memory location = V2000,
Channel 1 resolution = 14 bits,
Channel 1 engineering units = 0.0–140.0 PSI,
Channel 1 input device = 0–5V or 0–10V transmitter.
NOTE:
The above examples use SP1 (which is always on) as a permissive contact for the engineering unit conversions.
X, C, etc. could also be used as a permissive contact.
