7.6.5.1 Zero Calibration Procedure

Since the zero gas concentration is defined as 0 ppb, it is not necessary to enter the expected zero value. The following Table 7-11 details the zero calibration procedure.

1.

Press CAL

The M200AU enters the calibrate mode from sample mode.

 

 

NOTE:

 

 

The analyzer does not operate the zero/span valves in this mode,

 

 

the zero gas enters through the sample port. When the CAL

 

 

button is pressed, the adaptive filter is activated. This allows the

 

 

instrument to respond rapidly to concentration changes

 

 

regardless of their magnitude.

 

 

 

2.

Wait 10 min

Wait for reading to stabilize at the zero value.

 

 

 

3.

Press ZERO

If you change your mind after pressing ZERO, you can still

 

 

press EXIT here without zeroing the instrument.

 

 

 

4.

Press ENTR

Pressing ENTR actually changes the calculation equations.

 

 

 

5.

Press EXIT

M200AU returns to the SAMPLE mode.

 

 

 

7.6.5.2 NO/NOx Calibration Procedure

Adjust the NO concentration to approximately 80% of the URL of the NO channel. The expected NO and NOx span concentrations can be determined by measuring the cylinder and diluent flows and computing the resulting concentrations. If there is any NO2 impurity in the NO standard gas it should be taken into account when the NOx concentration is entered during the NO/NOx channel calibration. This is done by ADDING the impurity concentration to the NO concentration to get the NOx concentration for calibration. Calculate the exact NO and NOx concentrations as follows:

[NO ]OUT =

F NO x [NO ]STD

Equation 7 - 8

FT

 

 

Enter the respective concentrations using the procedure in Table 7-12. The expected span concentrations need not be re-entered each time a calibration is performed unless they are changed.

Enter the expected NOx and NO span gas concentrations:
