Introduction |
Model GFC7000TA Carbon Dioxide Analyzer |
1. INTRODUCTION
The Models GFC 7000TA and GFC 7000TM differ only in specifications; unless clearly differentiated, both models in this manual are referred to as the GFC 7000TA for simplification. The GFC 7000TA measures carbon dioxide CO2 by comparing infrared energy absorbed by a sample to that absorbed by a reference according to the Beer-Lambert law. This is accomplished by using a Gas Filter Wheel which alternately allows a high energy infrared light source to pass through a CO2 filled chamber and a chamber with no CO2 present.
The light then travels through the sample cell, which has a folded path. The energy loss through the sample cell is compared with the zero reference signal provided by the gas filter to produce an output proportional to concentration, with little effect from interfering gases within the sample. A nitrogen purge system is provided for the GFC wheel assembly to eliminate the effects of ambient CO2, if necessary.
This design produces superior zero and span stability and a high signal-to-noise ratio, allowing excellent sensitivity. Multi-tasking software gives real time indication of numerous operating parameters and provides automatic alarms if diagnostic limits are exceeded

3. GETTING STARTED
3.1. Unpacking and Initial Set Up
CAUTION
To avoid personal injury, always use two persons to lift and carry the Model GFC 7000TA.
WARNING
Never disconnect PCAs, wiring harnesses or electronic subassemblies while the instrument is under power.
CAUTION – Avoid Warranty Invalidation
Printed circuit assemblies (PCAs) are sensitive to electro-static discharges too small to be felt by the human nervous system. Damage resulting from failure to use ESD protection when working with electronic assemblies will void the instrument warranty.
See A Primer on Electro-Static Discharge in this manual for more information on preventing ESD damage.
NOTE
It is recommended that you store shipping containers/materials for future use if/when the instrument should be returned to the factory for repair and/or calibration service. See Warranty section in this manual and shipping procedures on our Website at:
http://www.teledyne-api.com under Customer Support > Return Authorization.
1.Verify that there is no apparent external shipping damage. If damage has occurred, please advise the shipper first, then Teledyne Instruments.
2.Included with your analyzer is a printed record of the final performance characterization performed on your instrument at the factory. This record, titled Final Test and Validation Data Sheet (P/N 04596) is an important quality assurance and calibration record for this instrument. It should be placed in the quality records file for this instrument.
3.Carefully remove the top cover of the analyzer and check for internal shipping damage.
Remove the set-screw located in the top, center of the Front panel.
Remove the 2 screws fastening the top cover to the unit (one per side towards the rear).
Slide the cover backwards until it clears the analyzer’s front bezel.
Lift the cover straight up.

Figure 3-2: Display Screen and Touch Control
CAUTION – Avoid Damaging Touchscreen
Do not use hard-surfaced instruments such as pens to operate the touchscreen.
The front panel liquid crystal display includes touch control. Upon analyzer start-up, the display shows a splash screen and other initialization indicators before the main display appears, similar to Figure 3-2 above (may or may not display a Fault alarm). The LEDs on the display screen indicate the Sample, Calibration and Fault states; also on the screen is the gas concentration field (Conc), which displays realtime readouts for the primary gas and for the secondary gas if installed. The display screen also shows which mode the analyzer is currently in (Mode field), as well as messages and data (Param field). Along the bottom of the screen is a row of touch control buttons; only those that are currently applicable will have a label. Table 3-1 provides detailed information for each component of the screen.
