GxT Ferret 14 5-Gas Manual - Manual (Page 2)

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 warmup screen. After a two
minute warmup and a one minute zero, you are ready to begin measuring gases.
The analyzer defaults to the composite screen. If the extended warmup is selected,
then analyzer has a 15 minute warmup and a one minute zero.
To change the setup for the analyzer, press the NEXT Key.

BUTTONS & CONTROLS
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 flow of exhaust. The water
separator should not be vertical or
horizontal, and should not be in the direct
flow of the exhaust. When used during a
road test, please use the included chain,
or a hose clamp to secure the probe in
the tailpipe.
Spark Pickup
Clamp the RED spark pickup around any
sparkplug wire with the “Spark Plug” label facing
towards the sparkplug. On systems where no
spark plug wires are available, the pickup may
be placed around the wire feeding the coil
primary.
Temperature Probe
An oil temperature probe and extension lead
can be connected to the Control Module
WARNING - Adjust the clamp to the length of
the vehicle oil dip stick before inserting into the
dip stick tube on the vehicle

DISPLAYING EXHAUST MEASUREMENTS
Composite Screen
The composite screen displays all five
gases, air fuel ration (AFR), Lambda (l),
RPM and Temperature. The screen also
shows the status of the memory used
during the record functions. Press the
NEXT button to go to the main selection screen.
Bar Graph Screen
Press either the Up or Down select
buttons to alter nate between the
composite, Bar graph and Big Digit

the actual gas readings compared to the emissions cutpoints that are selected when
a vehicle setup is performed. See page 12 to learn how to manually set the cutpoints.
Press the NEXT button to go to the main selection screen.
Big Digit Screen
Press either the Up or Down select
buttons to alter nate between the
composite, Bar graph 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.
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. Use
the SELECT buttons to move the selection arrow to Engine Setup then press the

ENGINE SETUP
CALIBRATION & ROUTINE SERVICE
Please refer to the Calibration Manual for information on the routine care and
service your analyzer requires.
Please note the analyzer does require routine service that includes: Gas Calibra-
tion, Filter replacement, Nox and O2 sensor replacement.
Setting Cutpoints
You can set the cutpoints used in the bar graph screen two different ways. One way
is to use the Emissions Selection Screen where you select the year, and size of the
vehicle. This will program the bargraph maximums to two times the limit used by the
ASM test method. The second way is to directly program the cutpoints manually.
Emissions Selection Screen
Use the SELECT buttons to choose the
year of the vehicle, then press the NEXT
button.
Use the SELECT buttons to choose the
size of the vehicle, then press the NEXT
button. You will be returned to the
analyzer setup screen.
If you want to manually configure the
limits used in the bar graph screen,
select Other, then press next. The
following screen will appear. Press the
arrow keys to move the selection arrow
to the limit you want to change. Press
NEXT to change the limits. When
finished, select CONTINUE. If you save the setup the cutpoints will be saved as well.
