The driving trial enables the vehicle’s internal RPM sensor to establish a connection to the driven
speed. The roller speed of the dyno vehicle is converted to an RPM. On the basis of this vehicle
transmission, the corresponding RPM value can also be shown on the screen of the test which
follows.
The RPM value for the driving trial is shown in rot/min. The adjustment RPM selected must be high
enough that it can be reached with the next to last gear ( test gear / gear transmission close to 1:1)
.
During the test which follows, the software converts the current speed in an engine RPM. (Please
note: The calculated RPM only agrees with the actual RPM of the power measurement when
driving with the 'Test gear' .)
The driving trial makes no sense on automatic vehicles without converter lockup, because the
engine RPM deviates due to the converter slip.
1 Position the vehicle on the dyno and fix it.
2 Use the menu point RPM SETTINGS in the
main screen.
3 Select DRIVING TRIAL from the list.
4 Enter the adjustment RPM and confirm with
<ENTER>.
5 Accelerate the vehicle in test gear up to the
pre-set RPM. Pay attention to the vehicle’s
RPM sensor.
6 Hold the RPM constant for a few seconds.
7 This RPM is stored.
