SECTION 9.6 – Calibration Quality Analysis
This section describes how to judge the effectiveness of a recently performed
calibration.
SECTION 9.7 – Gas Flow Calibration
This section describes how to adjust the gas flow calculations made by the CPU based
on pressure and flow sensor readings.
Note Throughout this Section are various diagrams showing pneumatic connections
between the T200 and various other pieces of equipment such as calibrators and
zero air sources.
These diagrams are only intended to be schematic representations of these
connections and do not reflect actual physical locations of equipment and fitting
location or orientation.
Contact your regional EPA or other appropriate governing agency for more
detailed recommendations.
9.1. BEFORE CALIBRATION
The calibration procedures in this section assume that the range mode, analog range and
units of measure have already been selected for the analyzer. If this has not been done,
please do so before continuing (see Section 5.4.3 for instructions).
Note If any problems occur while performing the following calibration procedures,
refer to Section 12.1 for troubleshooting tips.
9.1.1. REQUIRED EQUIPMENT, SUPPLIES, AND EXPENDABLES
Calibration of the T200 requires:

Zero-air source.

Span gas source.

Gas lines - all gas line materials should be stainless steel or Teflon-type (PTFE or
FEP).

High-concentration NO gas transported over long distances may require
stainless steel to avoid oxidation of NO due to the possibility of O
2
diffusing into
the tubing.

A recording device such as a strip-chart recorder and/or data logger (optional).

For electronic documentation, the internal data acquisition system (DAS) can be
used.
