The operator must now select if the engine speed can be measured.
If the engine speed can be measured, the operator must attach the MGT300/R RPM
measuring device to the vehicle as indicated on the display. If not, then the operator
must use the tachometer fitted to the vehicle to ensure that the RPM is within the
correct range during the test. For more information on connecting the RPM measuring
device see section 6.4.4.
The software will now perform a “HC HANG UP CHECK”. This is a short automatic test
to ensure that the analyser does not contain any Hydro Carbon (fuel) residue that could
affect the end result of the emissions test. The maximum permissible amount of HC
residue is 20ppm. If the HC test fails, this will be because the residue is too high. The
operator will be given the option to repeat the test or abort the test. To purge the system
of residual HC the pipework and filters should be cleaned and the unit be allowed to
take in clean fresh air for a short period of time.
