Calibration Procedures Model GFC7001E Carbon Dioxide Analyzer

9.CALIBRATION PROCEDURES

This section contains a variety of information regarding the various methods for calibrating a GFC 7001E/EM 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 GFC 7001E/EM ANALYZER IN ITS BASE CONFIGURATION

This section describes the procedure for checking the calibrating of the GFC 7001E/EM and calibrating the instrument with no zero/span valves installed or if installed, not operating.

It requires that zero air and span gas is inlet through the SAMPLE port.

Also included are instructions for selecting the reporting range to be calibrated when the GFC 7001E/EM Analyzer is set to operate in either the DUAL or AUTO reporting range modes.

SECTION 9.3 – MANUAL CALIBRATION AND CAL CHECKS WITH 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.

Instructions on activating the zero/span valves via the control in contact closures of the analyzers external digital I/O.

SECTION 9.4 – 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. NOTE: This practice is not approved by the US EPA.

SECTION 9.5 – CO CALIBRATION QUALITY ANALYSIS

This section describes how to judge the effectiveness of a recently performed calibration.

SECTION 9.6 – CALIBRATION OF GFC 7001E/EM ANALYZER’S ELECTRONIC SUBSYSTEMS

This section describes how to perform calibrations of the GFC 7001E/EM Analyzer’s electronic systems, including:

Dark Calibration of the optical bench.

The pressure and flow sensors.

SECTION 9.7 – CALIBRATION OF OPTIONAL GAS SENSORS

This section describes how to perform calibrations of the various optional sensors available on the GFC 7001E/EM Analyzers, including:

The O2 Sensor, and;

The CO2 Sensor.

NOTE

Throughout this section are various diagrams showing pneumatic connections between the GFC

7001E/EM 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.
