9. CALIBRATION PROCEDURES

This section contains a variety of information regarding the various methods for
calibrating a T803 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 of the T803
Analyzer
This section describes the procedure for checking the calibration of the T803 and
calibrating the instrument. Also included are instructions for selecting the
reporting range to be calibrated when the T803 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 T803’s Electronic Subsystems
This section describes how to perform calibrations of the T803’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 this instrument 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.
