7 Accelerate the vehicle gently but continuous-
ly 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 auto-
matically determined after the clutch is dis-
engaged.
11 To evaluate the measurement, see section
"
Identical Functions
" and section "
Perfor-
mance 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 en-
tered 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.
