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

7.2Manual Zero/Span Check or Calibration with Zero/Span Valves Option

The Zero/Span valve option can be operated from the front panel keyboard. In the Zero/Span valve option the zero and span gas come into the valves through ports on the rear panel of the instrument.

Step Number

Action

Comment

1.

Press CALZ

The analyzer enters the zero calibrate mode. This switches the

 

 

sample/cal and zero/span valves to allow zero gas to come in

 

 

through the zero gas inlet port in the rear panel. When the

 

 

CALZ 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.

 

 

 

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,

 

 

forcing the reading to zero.

 

 

 

5.

Press EXIT

M200AU returns to sample mode. Immediately after

 

 

calibration, readings do not go into the DAS averages.

 

 

 

Refer to Table 7-3 to enter expected NO and NOx values.
