Perform at least once every
quarter or anytime a level span
check indicates a discrepancy,
or after maintenance which
may affect the calibration;
Section 2.5 (Q.A. Manual)
Either a strip chart recorder, data acquisition system, digital data acquisition system
should be used to record the data from the Mode; T101 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.
To assure data of desired quality, two considerations are essential: (1) the measurement
process must be in statistical control at the time of the measurement and (2) the
systematic errors, when combined with the random variation in the measurement process,
must result in a suitably small uncertainty.
Evidence of good quality data includes documentation of the quality control checks and
the independent audits of the measurement process by recording data on specific forms or
on a quality control chart and by using materials, instruments, and measurement
procedures that can be traced to appropriate standards of reference. To establish
traceability, data must be obtained routinely by repeat measurements of standard
reference samples (primary, secondary, and/or working standards). More specifically,
working calibration standards must be traceable to standards of higher accuracy, such as
those listed in Table 7-1.
Cylinders of working gas traceable to NIST-SRM's (called EPA Protocol Calibration
Gas) are also commercially available (from sources such as Scott Specialty Gases, etc.).
Teledyne ML does not recommend the use of permeation tubes as a source of span gas for
EPA protocol calibration operations.
