Teledyne GFC 7001EM operation manual Glossary, Term Description/Definition

FAQs Model GFC7001E Carbon Dioxide Analyzer

Q:How do I measure the sample flow?

A:Sample flow is measured by attaching a calibrated rotameter, wet test meter, or other flow-measuring device to the sample inlet port when the instrument is operating. The sample flow should be 800 cm3/min 10%. See Section 12.3.4.

Q:How long does the IR source last? A: Typical lifetime is about 2-3 years.

Q:Can I automate the calibration of my analyzer?

A:Any analyzer with zero/span valve or IZS option can be automatically calibrated using the instrument’s AutoCal feature. The setup of this option is located in Section 9.4.

Q:Can I use the IZS option to calibrate the analyzer?

A:Yes. However, whereas this may be acceptable for basic calibration checks, the IZS option is not permitted as a calibration source in applications following US EPA protocols.

To achieve highest accuracy, it is recommended to use cylinders of calibrated span gases in combination with a zero air source.

Q:My analyzer has the optional, user-configurable analog output channels. How do I program and use them? A: Instructions for this can be found in Appendix E .

Q:What is the averaging time for an GFC 7001E/EM?

A:The default averaging time, optimized for ambient pollution monitoring, is 150 seconds for stable concentrations and 10 seconds for rapidly changing concentrations; See Section 11.5.12 for more information. However, it is adjustable over a range of 0.5 second to 200 seconds (please contact customer service for more information).
