The graph below illustrates a typical SOLA II Flare calibration.
Figure 5-25. Typical SOLA II Flare calibration
Prior to calibrating the instrument, the sulfur concentration expected at the two
points must be entered in the calibration setup menus (Configuration >
Calibration Setup). In the software, these points are referred to as high and low
calibration values.
For the graph above, the values would be:
Low cal value = 0.00 ppm
High cal value = 100.00 ppm
The high calibration value needs to be as close as possible to the full range
sulfur concentration expected in the process, and the low calibration value is
normally set to zero so that only one standard is required for calibration.
The high and low calibration can be performed independently. Changing either
one of the calibration points will change the slope of the line. This is illustrated
in the next two graphs.
Figure 5-26. High calibration
Low cal = 555.560 kHz
High cal = 15,000.000 kHz
