7 Accelerate the vehicle gently but
continuously up to the second to last gear.
As soon as the start speed is reached, the
analog display changes to green.
8 Then accelerate to full throttle. Pay
attention during the shifting phase that the
vehicle is not accelerated past 50 km/h
otherwise the test will begin before the test
gear has been reached.
9 Shortly before the max. RPM has been
reached disengage the clutch and release
the gas pedal.
Use the button <F6 LOAD> to load stored measurements and display in the background. A max.
of 3 additional curves can be placed in the background.
10 After a successful measurement the engine
power and torque are displayed (if an RPM
signal is available).
The engine power accrues from the wheel
power plus the drag power, which is
automatically determined after the clutch is
disengaged.
11 To evaluate the measurement, see section
" Identical Functions " and section
" Performance curves ".
Continuous Measurement with Automatic Transmission and Converter Slip Measurement
1 Position the vehicle on the dyno and fix it.
2 Open menu MEASURE ENGINE POWER and then menu item CONTINUOUS MEASUREMENT.
3 Select the vehicle data, or, if available, load them from the database with <F6 DATABASE>.
4 Use the button <F8 CONTINUE>.
For automatic transmissions with torque converter lock-up clutches a value of 0.0 % must be
entered if using manual entry.
5 Select the RPM source or the RPM sensor and the appropriate box.
6 Use the button <F8 CONTINUE>.
The driving trial makes no sense for automatic transmission vehicles without torque converter
lock-up clutches, because the engine RPM deviates due to the converter slip.
When accelerating pay attention that the vehicle’s "Kick -Down" is not triggered. If this is the
case, the test must be cancelled and repeated.
7 Accelerate the vehicle in the test gear (next to last gear) until the max. RPM is reached.
