7.8.3 Data Recording Device

Either a strip chart recorder, data acquisition system, digital data acquisition system should be
used to record the data from the 6200A 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.

7.8.4 Dynamic Multipoint Span Calibration

Dynamic calibration involves introducing gas samples of known concentrations to an instrument
in order to adjust the instrument to a predetermined sensitivity and to derive a calibration
relationship. A minimum of three reference points and one zero point uniformly spaced covering
0 to 80 percent of the operating range are recommended to define this relationship.
The analyzer's recorded response is compared with the known concentration to derive the
calibration relationship.
