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
