Use the menu point SPECIAL SETTINGS to change the time period, the sensitivity and the delay
for the performance measurement.
1 Using the corresponding button , the values
can be increased or decreased: <+> bzw.
<->.
2 Use <F8 IMPORT> to import the settings.
Use <F7 STANDARD> to load the standard
settings.
•
Time period of the wheel performance measurement with continuous power measurement
If the measurement under full load takes too long, this leads to an overheating of the charging
air temperature. A smaller value should be set. If the measurement is too fast, no sufficient
boost pressure will not build up. The value should therefore be raised.
•
Sensitivity for the automatic recognition of the roll out trial
If the roll out trial is not automatically recognized, the sensitivity should be raised. If the wheel
power measurement is then erroneously terminated too early, a smaller sensitivity should be se-
lected.
•
Delay until the drag power recording begins
If a clear bend is seen at the end of the drag power (up and then down) , the time until the re-
cording begins should be increased. If the drag power could not be measured because the ve-
hicle roll out too fast, the value should be decreased.
•
Speed at which the measurement begins and the roll out trial ends
If it is not possible to go into the test gear before the power measurement starts, the values
should be increased. If, however, the roll out trial is too short meaning that no drag power is
measured, the value can be decreased.
