12 Standard test (MID)
From the Petrol menu the Standard test (MID) can be selected. The Standard test provides a complete engine
analysis in which different parameters are measured and displayed live, for a quick and accurate diagnosis.
IMPORTANT:
Do not enter the Standard test with the sample probe in the vehicle exhaust. When Standard test is
selected the INNOVA 3000 automatically performs a zero calibration, if it is required. If a zero calibration is
performed INNOVA 3000 will adjust and set the gas measuring zero reference points and the oxygen concentration
is calibrated to 20.9% vol. The zero calibration will last 60 seconds.
Following a zero calibration the INNOVA 3000 may perform a HC residue check. This HC residue check will last 20
seconds. The INNOVA 3000 samples the HC levels in the ambient air and residual HC in the gas sampling system.
The HC concentration must not exceed 20ppm vol. If after 20 seconds the HC levels are above 20ppm vol. the
program will abort back to menu. If the HC levels are below 20ppm vol. the program will continue to the Standard
test page.
Ensure the sample probe is NOT in the vehicle exhaust during the HC residue check!
To perform a Standard test, insert the sample probe in the exhaust of the vehicle. During the Standard test all gas
concentrations are shown live, simultaneously on the monitor of the INNOVA 3000. In addition to the gas
measurements the lambda value (
‘
’) is calculated. This calculation is made with help of the Brettschneider formula.
The value gives an indication to the combustion efficiency of the vehicle.
RPM and Oil temperature is also shown on screen in the Standard test. The measured parameters available during
the Standard test are:

, the corrected CO value will only be shown if the CO

value is equal or larger then 5 percent volume. This
value is calculated as followed:
CO + CO
