The following section describes the basic method for manually calibrating the T200
NO analyzer.

If the analyzer‟s reporting range is set for the AUTO range mode, a step will appear for
selecting which range is to be calibrated (LOW or HIGH). Each of these two ranges
MUST be calibrated separately.
The expected concentrations for both NOx and NO are usually set to the same
value unless the conversion efficiency is not equal to 1.000 or not entered
properly in the conversion efficiency setting.
When setting expected concentration values, consider impurities in your span
gas source (e.g. NO often contains 1-3% NO
The NO and NO span gas concentrations should be 80% of range of concentration

values likely to be encountered in your application. The default factory reporting range
setting is 500 ppb and the default span gas concentration is 400.0 ppb.
