GxT Ferret 54 ENGINE DIAGNOSTIC CENTER - Manual (Page 70)

EMISSIONS
The Gas Analyzer must be connected to use these tests. Refer to the GAS THEORY section
of this manual for information on preconditioning the vehicle, sampling techniques, and
interpretation of readings.
Emissions is not available when Engine Setup "Ignition" is set to
Diesel .
When power is applied to the Diagnostic Center, a warm up of the Gas Analyzer is required.
After warm up completes, the Gas Detector must be ZEROed. The ZERO process is
automatically performed the first time a test is selected that requires use of the Gas Analyzer.
The SELECT keys are used to choose among three display formats.
COMPOSITE

Temperature (if the Oil Temperature Probe is connected).
