Model 9110TH NOx Analyzer Calibration Procedures

9. CALIBRATION PROCEDURES

This section contains information for calibrating a 9110T NOx 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.
