SERVOPRO NOx Analyzers Page
Introduce span gas into the rear of the analyzer. Press to go to the
Diagnostic
Values screen to view the current diagnostic values. Check the temperatures and
pressures to be sure they are within their limits. If all diagnostic values are within their
limits, press the back button to return to the Manual Span Calibration screen.
When the concentration number has stabilized, press to set the span calibration. The
calibration should now be complete.
If the span calibration was successful, the screen will say ***Saved Current***. If the
calibration was unsuccessful, the screen will say Outside Deviation Limits. See the
Manual Zero Calibration section for examples of screens showing successful and
unsuccessful calibrations.
If the span calibration is unsuccessful, check the following:
1. Make sure the correct gas was introduced into the analyzer.
2. Verify the
Diagnostic Values while flowing gas.
3. Check Span Gas Deviations under
