7 Accelerate the vehicle in the test gear (next to last gear) until the max. RPM is reached.
8 Slowly reduce the throttle once the max. RPM is reached until the message appears "Shift
gears and accelerate vehicle to XXX km/h. When this message appears, shift to the last gear
and accelerate to the target speed (the previously reached speed + 10%) .
9 Then switch to position N and release the throttle.
The message "Shift to position N" appears and shortly thereafter "Let vehicle coast down".
Let the vehicle coast down to start speed while in gear position N.
The test gear must always be the next to the last gear. The measurement starts after a preset start
speed has been exceeded, which is normally set at 50 km/h for Car dynos.
Converter slip measurement
10 Accelerate the vehicle in the test gear (next to last gear) again to the target speed.
The message line shows the message "Accelerate vehicle to XXX km/h ".
11 When the target speed has been reached, release the throttle and let the vehicle coast down to
standstill in test gear (not neutral).
12 After successful measurement, the engine power, wheel power, drag power and torque (if an
RPM signal is available) is shown.
13 To evaluate the measurement, see sections "
Identical Functions
" and "
Performance curves
".
The converter slip appears only on the printout, not on the measurement screen.
If the vehicle shifts up at the end of the measurement, this section of the diagram will be removed
later. Instead, the software compares the ratio between engine rpm and speed.
