Notes:

 

 

∙Since the zero gas concentration is defined as 0 ppb, it is not necessary to enter the expected concentration values.

∙Both the TNx and NOx channels must be zeroed individually. When you zero the NOx channel both the offsets for NOx and NO are configured. All readings should display zero following this action.

∙It is recommended that the calibration of both the TNx and NOx channels be done at one time.

∙Always confirm that excess zero air is flowing past the sample or zero port, if the Zero/Span option is present, on the rear of the M501 NH3, converter. There should always be some excess flow. If insufficient flow is supplied to the analyzer ambient gas will be entrained and the zero offset values will be incorrect. However, it is important not to over pressurize the analyzer.

∙It is a good idea to allow the analyzer to sample zero gas for extended periods following zero calibration. Large drifts can signify leaks or indicate an issue with the zero air source.

2.2SPANNING THE ANALYZER WITH NITRIC OXIDE GAS

The analyzer can be spanned by either applying nitric oxide gas straight to the Sample port or through the Zero/Span valve option, if installed. It is important to remember that if the analyzer was previously sampling ammonia gas, prior to conducting a nitric oxide span calibration, it will take some period of time before the TNx channel stabilizes. The process of spanning the analyzer consists of diluting bottled gas, using a calibrator and delivering to the analyzer. The
