9. CALIBRATION PROCEDURES
This section contains a variety of information regarding the various methods for
calibrating a T801 as well as other supporting information
This section is organized as follows:
Section 9.1 – Before Calibration - contains general information yo
u should know
before calibrating the analyzer.
SECTION 9.2 – Manual Calibration Checks and Calibration - describes the
procedure for checking the calibration of the T801 and calibrating the instrument.
Also included are instructions for sele
cting the reporting range to be calibrated
when the T801 analyzer is set to operate in either the DUAL or AUTO reporting
range modes.
SECTION 9.3 – Assessing Calibration Quality - describes how to judge the
effectiveness
of a recently performed calibration.
SECTION 9.4 – Calibrating the Electronic Subsystems - describes how to
perform
calibrations of the T801’s electronic systems, including:
adjusting the analyzers internal flow sensor
adjusting the analyzers internal pressure sensor
Note
Throughout this Section are various diagrams showing pneumatic
connections between the T801 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..
