CO/SO2
Audit and Calibration
Purpose: The CO/SO2 audit and
calibration assures that the CO and SO2 analyzers/systems have the correct
response. This can be accomplished by
introducing a known quantity of gas to the inlet and auditing the response on
the instrument. The terminology for this
type of audit is GRC (Gas Replacement Calibration). Each GRC has a RF (Response Factor). The RF value should be 1.00 +/- 2% when
complete.

Wait 13 minutes for the CO number to
be stable. Press Get Data on the Query
Data Tool. If the query data numbers are
larger or approximately equal to the number on Site Manager then the data is
stable and an average can be taken.
8.
Enter the CO value into gas
calibration worksheet if the CO Zero is not within specification follow the
steps below to calibrate.
9.
Turn off CO/SO2/SO4 Filter Zero for 3
minutes for First Light to capture audit data point.
10.
To calibrate turn on the CO Zero and
wait 5 minutes for the CO number to be stable.
11.
The 48CTL analyzer should already be
in the adjustment screen (follow step 6).
Use the up and down arrows to adjust the Background number so that the
Site Manager CO number is ~200 PPB or the analyzer is ~0.200 PPM. When this is complete press enter on the
analyzer.
12.
Wait 5 minutes for the CO number to
be stable. Press Get Data on the Query

bottom number is the BKG number.
6.
Wait 13 minutes until the SO4 number
is stable. Contact Plano if not stable
within 13 minutes. Press Get Data on the
query data tool. If the data numbers are
approximately equal to the number on Site Manager then the data is stable and
an average can be taken.
7.
Enter the SO4 data in the As Found

1.00. If it isn’t, adjust the BKG or
Zero Pot.
8.
Turn off CO/SO2 Zero and wait for 3
minutes for First Light to capture data point.
9.
To calibrate turn back on the CO/SO2
Zero, wait for 5 minutes to adjust the SO2 BKG value to get the SO2 Zero to be
within specification. If you have a
43CTL analyzer it should already be in the adjustment screen. Use the up and down arrows to adjust the
Background number so that the SO2 PPB number is ~1.00. When this is complete press Enter on the
analyzer.
10.
Once the value has been adjusted
correctly, wait 5 minutes for First Light to capture new data point and press
Get Data on the Query Data tool.

a.
On 43CTL analyzers press menu. Scroll down to CAL FACTORS and press
ENTER. Go to the SO2 COEF and press
enter – Set the SO2 COEF to 1.0. The PMT
can be adjusted by taking the top off of the analyzer. With the top of the analyzer off, look on
the left side of the bulkhead at the front.
There is a blue box with an orange grommet on the top. Inside the grommet is the PMT adjustment
screw. Slowly adjust the analyzer until
the SO2 ppb on the analyzer, or SO4 on Site Manager, is approximately equal to
the Actual Expected value from the As Found section. The PMT adjustment screw on the inside of the
analyzer is a coarse adjustment and the SO2 COEF is a fine adjustment. The SO2 COEF should always be close to a standard
of 1.00 but it can be used to adjust the instrument to a tighter
tolerance. The SO2 COEF will adjust the
instrument in smaller increments than the PMT adjustment. Replace the top of the analyzer.
8.
When the analyzer adjustments are
complete, let the analyzer stabilize for 5 minutes. Press Get Data on the Query Data Tool.
