  • Page 46: Getting 4 To 20 Ma For Temperature And Pressure

    NOTE: The engineering units are as set in the Calibration (Sub Menu). Go to that section for more detailed information. In the example above, assume full scale flow is 100 SCFM. As a result, a 20 mA output equals 100 SCFM and 4 mA output equals 0.00000 SCFM. These values are fixed for flow. The output is linear between these two points, in this example, if we had a flow of 50 SCFM, the output would be 12 mA.
