Introduction The GasLink II™ is the ultimate in portable gas analyzers. Small and portable, it can easily be taken on road tests and stored in a toolbox. Buttons & Controls Next Button Press this button to make a selection, or to access the main menu. Rec/Pause/Play Button Press this button to activate the record and playback functions of the analyzer. See the record section of the manual for more information.
Connecting to the Vehicle Battery Power Leads Connect the RED lead to the Battery Positive, and the BLACK lead to Battery Negative post. The analyzer is protected in case you connect the leads improperly. Exhaust Sample Hose Insert the sample hose into the tailpipe. Be sure to route the sample hose away from the exhaust flow. The water separator should not be vertical or horizontal, and should not be directly in the exhaust flow.
Start-Up & Warm-Up When power is applied to the unit, the start-up screen appears for a few seconds. This screen shows the date of the last gas calibration and what fuel type and RPM input the analyzer is going to use. The analyzer then proceeds automatically to the warm-up screen. After a two minute warm-up and a thirty second zero, you are ready to begin measuring gases. The analyzer defaults to the composite screen.
Big Digit Screen Press either the Up or Down select buttons to alternate between the composite, Grams per Mile and Big Digit screens. The big digit screen displays the five gases and RPM in a large format. Press the NEXT button to go to the main selection screen. Grams Per Mile Screen Press either the Up or Down select buttons to alternate between the composite, Grams per Mile and Big Digit screens. The Grams Per Mile Screen displays the estimated grams per mile of all gases.
Analyzer Setups Analyzer Setup Screen Use the SELECT buttons to move the selection arrow to Analyzer Setup then press the NEXT button. The following screen will appear Use the SELECT button to select which analyzer setup you wish to change, then press the NEXT button. Select EXIT to return to the Setup Choices Screen. Change the Contrast of the LCD Use the SELECT buttons to move the select from one of 4 contrast levels. Press the NEXT button to return to the Engine Setup Screen.
Program a Custom Header Up to four lines of header information can be entered. The header is created in the top two lines of the screen. The bottom two lines contain the characters that may be used in the header and the control characters. There are two cursors. The Placement Cursor is the flashing box that indicates where the next character will be placed. The Selection Cursor is the flashing underline.
Engine Setup Main Menu Screen From the Main Menu, use the SELECT buttons to move the arrow up to Analyzer & Engine Setups then press the NEXT button. The following screen will appear. Setup Choices Screen Use the SELECT buttons to move the selection arrow to Engine Setup then press the NEXT button. Select EXIT to return to the Main Menu. Engine Setup Screen Use the SELECT button to select which engine setup you wish to change, then press the NEXT button. Select EXIT to return to the Main menu.
RPM Source Use the SELECT buttons to choose the RPM source, then press the NEXT button. You will be returned to the analyzer setup screen. Selecting Distributor or DIS requires that the RED Inductive Pickup be connect around the sparkplug wire. For vehicles that do not have spark plug wires use the No Spark Wire selection. No Spark Wire RPM input Use the SELECT buttons to choose the number of cylinders, then press the NEXT button.
Report Printing From the Main Menu, use the SELECT buttons to move the selection arrow to REPORT then press the NEXT button. The following screen will appear. Report Screen Use the SELECT buttons to move the selection arrow to select one of two report functions, or perform a Visual Inspection. Press NEXT to begin printing the report. Print Report (All Results) will print the entire record of recorded data.
Maintenance - Zero & Purge Zero Use the SELECT buttons to move the selection arrow to select one of the Calibration and Maintenance program. When you select Zero, the analyzer will stop sampling gas from the sample hose and will perform a zero of the bench. There is no need to remove the sample hose from the tailpipe. Zeroing the analyzer periodically will maintain the accuracy of the unit during testing.
Maintenance - Calibrate The calibrate program is used to gas calibrate the analyzer. Gas calibration should be performed monthly. This procedure will require the use of the calibration adapter that was included with the unit. Connect the long end of the hose directly to the gas analyzer and connect the filter end of the adapter to the Gas bottle. When you first enter the Calibrate program you will be asked to confirm or change the gas values to match the bottle of calibration gas you are using.
The analyzer will zero the gas bench then ask you to turn on the gas valve on and adjust the pressure regulator until the bar graph is between the two arrows. The analyzer will display a 60 second count down message. If the calibration was successful you will see the following screen. If you experience an error in performing a Gas Calibration, please retry the procedure again. If you still have trouble, contract customer service at (800) 627-5655 for additional help.
Record & Playback You may press the REC/PAUSE/PLAY button any time you are measuring emissions. If you are using the Big Digit display, and press Record the display will revert to the Bar Graph Display. The word RECORDING will appear on the display when the analyzer is recording. When you reenter the emissions test, the following screen will appear. If you select EXAMINE data you can choose from different sections. Up to six different sections can be held in memory.
Gas Theory The content of an engine’s exhaust stream depends on the efficiency of the combustion process. Ideally, pure fuel (hydrogen and carbon) and oxygen would enter the combustion chamber in precisely the right amounts (called stoichiometry), and the mixture would be ignited at just the right moment so that all of the oxygen would combine with all of the fuel.
Gas Theory AFR (Air Fuel Ratio), Lambda and Stoichiometry Stoichiometry is where air and fuel are in the proportions that provide the greatest combustion efficiency. The AFR (air to fuel ratio) is a number that describes the proportions of air and fuel. For gasoline, the AFR that represents the stoichiometric point is 14.7 parts of air to 1 part of fuel. Lambda is a normalized scale where 1.0 is the stoichiometric point for the fuel being used. So, for gasoline, you can multiply lambda by 14.
Gas Theory Carbon Monoxide (CO) Carbon monoxide is formed when there is not enough oxygen to support combustion. Fuel system problems are the usual cause of high CO. In carbureted engines high CO may be caused by: Dirty air filter, Sticking choke, Float not set properly, Idle mixture set too rich In fuel injected engines high CO readings may be caused by: Dirty air filter, Leaky injectors, High fuel rail pressure, Engine computer control malfunction.
Routine Maintenance Low Flow Message The low flow message can be caused by clogged or dirty filters, excessive water moisture in the filters, or an extremely cold pump assembly. If you get a low flow indication, follow the directions below to clear the message. If the Low Flow message goes away when the sample hose is disconnected, you have excessive water in the filter system, or the filters are dirty. Run the extended Purge a couple of times.
Warranty FERRET BRAND LIMITED PRODUCT WARRANTY GxT, Inc. of Cheboygan Michigan, warrants to the original purchaser that FERRET brand products are free from defects in materials and workmanship for a period of two years from date of purchase.

SAFETY PRECAUTIONS —Read All Instructions Before Using The Meter— • Always wear eye protection when testing vehicles. Be extra careful near batteries and moving parts. Do not lay tools on a battery. • Battery gas is highly explosive. a. If a battery explodes flush the acid away from persons skin with generous amounts of water. Follow up with a neutralizing solution of baking soda and then more water. Treat clothing, vehicle parts, and equipment similarly.
