4.13.5.8. Setting the Reporting Range Scale for an Analog Output
Note
Note
07270D DCN7141
Once the DAS parameter has been set, the top end of the scale must be selected. For
concentration values this should be equal to the expected maximum value for the
application. The analog channel will scale its output accordingly.
EXAMPLE:
DAS parameter being output: NXCNC1
Maximum value expected: 800 ppm
Output range; 10 V
Output: ... 0 ppm 0.000 V
100 ppm
200 ppm
400 ppm
750 ppm
Regardless of how the reporting range for an analog output channel is set, the
instrument will continue to measure NO, NO
physical range of the instrument (See Section 4.13.4.2 for information on Physical
range versus reporting range).
Each output channel can be programmed for a separate gas with independent reporting
range.
EXAMPLE:
A1  NXCNC1 (NOx Range 1) 0-1000 ppm NOx.
A1  NXCNC2 (NOx Range 2) 0-1250 ppm NOx.
A3  NOCNC1 (NOx Range 1) 0-500 ppm NO.
A4  N2CNC1 (NO2 Range 1) 0-750 ppm NO
While Range 1 for each gas type is often referred to as the LOW range and Range
2 as the HIGH range, this is simply a naming convention. The upper limit for each
range can be set to any value.
EXAMPLE: A1  NXCNC1 (NOx Range 1) 0-1500 ppm NOx
A2  NXCNC2 (NOx Range 2) 0-1000 ppm NOx
