9. CALIBRATION PROCEDURES
This section contains a variety of information regarding the various methods for
calibrating a T802 as well as other supporting information
This section is organized as follows:
Section 9.1 – Before Calibration
This section contains general information you should know before calibrating the
analyzer.
SECTION 9.2 – Manual Calibration Checks and Calibration
This section describes the procedure for checking the calibration of the T802 and
calibrating the instrument. Also included are instructions for selecting the
reporting range to be calibrated when the T802 analyzer is set to operate in either
the DUAL or AUTO reporting range modes.
SECTION 9.3 – Assessing Calibration Quality
This section describes how to judge the effectiveness of a recently performed
calibration.
SECTION 9.4 – Calibration of the T802’s Electronic Subsystems
This section describes how to perform calibrations of the T802’s electronic
systems, including:
adjusting the analyzers internal flow sensor
adjusting the analyzers internal pressure sensor
SECTION 9.5 – Calibration of the Optional CO2 Sensor
This section describes how to perform calibrations of the optional CO2 Sensor.
Note Throughout this Section are various diagrams showing pneumatic
connections between the T802 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..
