LAMBDA PROBE TEST ____________________________________________________________________ STARGAS
At the same time the graph curve, which displays the probe working,
changes into a straight line tending to a value next to 0 (zero) Volt.
After about 15 seconds select MEASURE again in order to check the correct
variation of the CO values and of the lambda coefficient.
Check in the lower box on the left the reset of the normal working values of
the whole system, starting from the ones that have been memorised in the
RICH MIXTURE ( 137 ) box.
It is also possible to check the same conditions in the graph where the trend
of the probe normal working will be displayed again after a resetting span.

Select the function ( 135 ) to display in the LEAN MIXTURE ( 136 ) square,
having a CYAN background, the CO and lambda factor values that
vary as a function of the mixture weakening.
Simultaneously the graph curve, which displays the probe functioning, turns
into a straight line tending to a value being near to 1 Volt or to 5 Volt,
depending on the kind of selected probe.
After about 15 seconds select MEASURE again in order to check the correct
variation of the CO values and of the lambda coefficient.
Check in the lower box on the left the reset of the normal working values of
the whole system, starting from the ones that have been memorised in the
LEAN MIXTURE ( 136 ) box.

Press MENU to display FUNCTIONS BAR whose icons have the same
functions as those previously described (see chapter 6.0).
