Remember until the unit has completed its warm up these parameters may not
have stabilized.
3.3. Initial Calibration Procedure
The next task is to calibrate the analyzer.
NOTE
If you are using the M400E for EPA monitoring, only the
calibration method described in Section 8 should be used.
NOTE
The detection of O
3
is subject to interference from a number of sources including,
SO
2
, NO
2
, NO, H
2
O AND aromatic hydrocarbon meta-xylene and Mercury vapor. The
Model 400E successfully rejects interference from all of these except Mercury Vapor.
Mercury Vapor absorbs radiation in the same wave-length band as O
3
but so much
more efficiently that its presence will render the analyzer useless for detecting O
3
.
If the Model 400E is installed in an environment where the presence of Mercury vapor
is suspected, specific tests should be conducted to reveal the amount of interference
and steps should be taken to remove the Mercury Vapor from the Sample Gas before
it enters the analyzer. For More information see Section 10.1.4.
