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 3-7.
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; GFC 7001E 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 Error! Reference source not found. 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.
