Figure 9-4 Leak Check (Gas) Initialization
•
Start the vehicle engine (if not already running) and insert the sample
probe fully into the exhaust tailpipe.
The unit will collect an exhaust gas sample from the vehicle and the CO
2
concentration will be continuously measured and displayed. When the
proper CO
2
threshold has been reached (+/- 5% vol) the screen will
indicate that a 20 second stabilisation period has begun. A status bar
representing a 20 second countdown will be shown (figure 10-5).
At the end of the stabilisation period the pump will switch off and the
screen will ask the operator to remove the probe from the tailpipe and
block the probe tip using the Probe Sealing Tool (p/n 7009E9317-46)
