Teledyne API Model 200AU NOX Analyzer Instruction Manual, 02293, Rev. F

7.1Manual Zero/Span Check or Cal with Zero/Span Gas in the Sample Port

The calibration of the instrument can be checked or adjusted using gas coming through the sample port. This method is often used when the calibration gas is supplied from an external calibrator and valve system.

This is the calibration procedure to use if the instrument is purchased without the Zero/Span Valve option.

Since the zero gas concentration is defined as 0 ppb, it is not necessary to enter the expected zero value. Table 7-2 details the zero calibration procedure with zero gas coming in through the sample port.

Comment

1.

Press CAL

The M200AU enters the calibrate mode from sample mode.

 

 

The zero gas must come in 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 zero value or for STABIL

 

 

reading to get to < 2 ppb.

 

 

 

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 sampling. Immediately after calibration,

 

 

data is not added to the DAS averages.
