Model 9110T NOx Analyzer Getting Started
Teledyne Analytical Instruments 80
VERIFYING THE EXPECTED NO
X
AND NO SPAN GAS CONCENTRATION
IMPORTANT
IMPACT ON READINGS OR DATA
Verify the PRECISE Concentration Value of the SPAN gases
independently.
If you supply NO gas to the analyzer, the values for expected NO and
NO
x
MUST be identical.
The NO
x
and NO span concentration values automatically defaults to 400.0 PPB and it is recommended
that calibration gases of that concentration be used for the initial calibration of the unit.
