ENERAL AFETY AZARD The GFC7001T/GFC7001TM Analyzer can be configured for both 100-130 V and 210-240 V at either 47 Hz or 63 Hz. To avoid damage to your analyzer, make sure that the AC power voltage matches the voltage indicated on the analyzer’s model/specs label (See Figure 3-4) before plugging the GFC7001T/GFC7001TM into line power.
Page 43: Connecting Analog Outputs
See Section 0 for details on setting up the DAS. 3.3.1.3. CONNECTING ANALOG OUTPUTS The GFC7001T is equipped with several analog output channels accessible through a connector on the back panel of the instrument. The standard configuration for these outputs is mVDC. An optional current loop output is available for each.
Page 44: Current Loop Analog Outputs (Option 41) Setup
Servicing or handling of circuit components requires electrostatic discharge protection, i.e. ESD grounding straps, mats and containers. Failure to use ESD protection when working with electronic assemblies will void the instrument warranty. Refer to Section 14 for more information on preventing ESD damage.

In the case of CO measurements made with the GFC7001T or GFC7001TM Analyzer, it is recommended that you use a span gas with a CO concentration equal to 80-90% of the measurement range for your application.
Page 70: Startup, Functional Checks, And Initial Calibration
The analyzer’s cover must be installed to ensure that the temperatures of the GFC Wheel and absorption cell assemblies are properly controlled. If you are unfamiliar with the GFC7001T/GFC7001TM theory of operation, we recommend that you read Section 13. For information on navigating the analyzer’s software menus, see the menu trees described in Appendix A.

Page 276: Measurement Fundamentals
13.2. MEASUREMENT FUNDAMENTALS In the most basic terms, the GFC7001T/GFC7001TM uses a high-energy heated element to generate a beam of broad-band IR light with a known intensity (measured during instrument calibration). This beam is directed through multi-pass cell filled with sample gas.
Page 277: Gas Filter Correlation
13.2.1. GAS FILTER CORRELATION Unfortunately, water vapor absorbs light at 4.7 µm too. To overcome the interfering effects of water vapor the GFC7001T/GFC7001TM adds another component to the IR light path called a Gas Filter Correlation (GFC) Wheel. Measurement Cell...
Page 278: The Measure Reference Ratio
13.2.1.2. THE MEASURE REFERENCE RATIO The GFC7001T/GFC7001TM determines the amount of CO in the sample chamber by computing the ratio between the peak of the measurement pulse (CO MEAS) and the peak of the reference pulse (CO REF).
Page 279: Figure 13-4: Affect Of Co In The Sample On Co Meas & Co Ref
Figure 13-4: Affect of CO in the Sample on CO MEAS & CO REF Once the GFC7001T/GFC7001TM has computed this ratio, a look-up table is used, with interpolation, to linearize the response of the instrument. This linearized concentration value is combined with calibration SLOPE and OFFSET values to produce the CO concentration which is then normalized for changes in sample pressure.
Page 280: Summary Interference Rejection
Figure 13-6: Chopped IR Signal 13.2.1.3. SUMMARY INTERFERENCE REJECTION The basic design of the GFC7001T/GFC7001TM rejects most of this interference at a 300:1 ratio. The two primary methods used to accomplish this are: • The 4.7μm band pass filter just before the IR sensor which allows the instrument to only react to IR absorption in the wavelength affected by CO.
Page 281: Flow Rate Control
13.3. FLOW RATE CONTROL To maintain a constant flow rate of the sample gas through the instrument, the GFC7001T/GFC7001TM uses a special flow control assembly located in the exhaust gas line. In instruments with the O sensor installed, a second flow control assembly is located between the O sensor assembly and the exhaust port.

2:1 pressure differential and not absolute pressure, the flow rate of the gas is also unaffected by ambient pressure fluctuations downstream. The critical flow orifice used in the GFC7001T/GFC7001TM is designed to provide a flow rate of 800 cc/min. 13.3.2. PARTICULATE FILTER The GFC7001T/GFC7001TM Analyzer comes equipped with a 47 mm diameter, Teflon, particulate filter with a 5 micron pore size.

Theory of Operation Teledyne API – Model T300/T300M CO Analyzer 13.4.4.3. ZERO/SPAN VALVE OPTIONS Any zero/span/shutoff valve options installed in the analyzer are controlled by a set of electronic switches located on the relay board. These switches, under CPU control, supply the +12VDC needed to activate each valve’s solenoid.

Theory of Operation Teledyne API – Model T300/T300M CO Analyzer EMPERATURE ENSOR A thermistor is attached to the motherboard. It measures the analyzer’s internal temperature. This information is stored by the CPU and can be viewed by the user for troubleshooting purposes via the front panel display (see Section 12.1.2).

FRONT PANEL TOUCHSCREEN/DISPLAY INTERFACE Users can input data and receive information directly through the front panel touchscreen display. The LCD display is controlled directly by the CPU board. The touchscreen is interfaced to the CPU by means of a touchscreen controller that connects to the CPU via the internal USB bus and emulates a computer mouse.
Page 299: Software Operation
Unlike other analyzers that average the output signal over a fixed time period, the GFC7001T/GFC7001TM averages over a set number of samples, where each sample is 0.2 seconds. This technique is known as boxcar averaging. During operation, the software automatically switches between two different length filters based on the conditions at hand.

13.5.4. TEMPERATURE AND PRESSURE COMPENSATION Changes in pressure can have a noticeable, effect on the CO concentration calculation. To account for this, the GFC7001T/GFC7001TM software includes a feature which allows the instrument to compensate for the CO calculations based on changes in ambient pressure.
