The reliability and usefulness of all data derived from any analyzer depends primarily
upon its state of calibration. To ensure accurate measurements of the CO levels:
1. The analyzer must be calibrated at the time of installation and recalibrated as
necessary.
2. In order to insure that high quality, accurate measurement information is obtained at
all times, the analyzer must be calibrated prior to use.
3. Calibrations should be carried out at the field-monitoring site.
4. The analyzer should be in operation for at least several hours (preferably overnight)
before calibration so that it is fully warmed up and its operation has stabilized.
5. If the instrument will be used on more than one range, it should be calibrated
separately on each applicable range.
6. Calibration documentation should be maintained with each analyzer and also in a
central backup file.
7. The true values of the calibration gases used must be traceable to NIST-SRMs See
Table 3-12.
10.1.2. CALIBRATION EQUIPMENT, SUPPLIES, AND
EXPENDABLES
The measurement of CO in ambient air requires a certain amount of basic sampling
equipment and supplemental supplies. The Quality Assurance Handbook Section 2.6
contains information about setting up the appropriate systems.
10.1.2.1. DATA RECORDING DEVICE
Either a strip chart recorder, data acquisition system, digital data acquisition system
should be used to record the data from the Mode; GFC7001T RS-232 port or analog
outputs. If analog readings are being used, the response of that system should be
checked against a NIST referenced voltage source or meter. Data recording device
should be capable of bi-polar operation so that negative readings can be recorded.
10.1.2.2. SPARE PARTS AND EXPENDABLE SUPPLIES
In addition to the basic equipment described in the Q.A. Handbook, it is necessary to
maintain an inventory of spare parts and expendable supplies. Section 11 describes the
parts that require periodic replacement and the frequency of replacement. Appendix B
of this Technical Manual contains a list of spare parts and kits of expendables supplies.
