9. CALIBRATION PROCEDURES
This section contains information for calibrating a 9110T NO
x
Analyzer as well as other supporting
information. For information on EPA protocol calibration, please refer to Section 10. This section is
organized as follows:
SECTION 9.1 – Before Calibration
This section contains general information you should know before about calibrating the analyzer.
SECTION 9.2 – Manual Calibration Checks and Calibration of the 9110T Analyzer in its Base
Configuration
This section describes:
 The procedure for checking the calibrating of the 9110T and calibrating the instrument with
no zero/span valves installed or if installed, not operating. It requires that zero air and span
gas be installed through the Sample port.
 Instructions for selecting the reporting range to be calibrated when the 9110T analyzer is set
to operate in either the IND or AUTO reporting range modes.
SECTION 9.3 – Manual Calibration with the Internal Span Gas Generator
This section describes:
 The procedure for manually checking the calibration of the instrument with optional internal
span gas generator installed.
 The procedure for manually calibrating the instrument using the optional internal span gas
generator.
 This practice is not approved by the US EPA.
SECTION 9.4 – Manual Calibration and Cal Checks with the Valve Options Installed
This section describes:
 The procedure for manually checking the calibration of the instrument with optional
zero/span valves option installed.
 The procedure for manually calibrating the instrument with zero/span valves and operating.
 Instructions on activating the zero/span valves via the control in contact closures of the
analyzers external digital I/O.
SECTION 9.5 – Automatic Zero/Span Cal/Check (AutoCal)
This section describes:
 The procedure for using the AutoCal feature of the analyzer to check or calibrate the
instrument.
 The AutoCal feature requires that either the zero/span valve option or the internal span gas
generator option be installed and operating.
SECTION 9.6 – Calibration Quality Analysis
