measurements.
$
Manual mode (refer to Section 5).
$
Automatic mode (refer to Section 6).
$
Super automatic mode (refer to Section 7).
$
All-wheel super automatic mode (refer to
Section 8).
i
Factory default settings:
Test routine P1 (brake test) and manual mode (nor-
mal operation).
The following brakes can be measured:
R
Front axle service brake.
R
Rear axle service brake.
R
Parking brake.
The brake test sequence can be selected by the

Notes on operation
!
When performing tests pay attention to the following
information on correct operation.
Remaining hazard warning!
The possibility of remaining hazards
cannot be excluded when using the brake
dynamometer.
¶
Heed the safety instructions given in the
"User information" manual 1 691 696 900!
¶
Wear protective clothing and equipment!
4.6.1
General information
¶
Always keep the vehicle straight when driving onto
the dynamometer.
¶
Ensure compliance with the permissible test and
driveover load (refer to technical data).
¶
Check the tire inflation pressure before starting
measurement.
¶
The vehicle must be unladen when testing.
¶
Remain in the vehicle during the test.
4.6.2
Notes on brake testing
¶
Make sure tires do not scrape against the frame of
the dynamometer.
¶
Keep to the maximum speed of 10 km/h when
driving onto or over the roller mechanism.
¶
Avoid abrupt steering action when checking the
front axle.
¶
Brake testing can only be performed if both the
wheels of one axle press the slip rollers down
within 5 seconds.
i
In the event of an excessive difference between
roller and wheel speed (>25%), the frictional force
between the wheel and test roller is measured
instead of the braking force. This measurement
result is of no use for brake testing.
!
Only drive off the set of rollers whilst the test
rollers are turning, i.e. measurement mode must be
active (manual operation in axle measuring mode or
automatic operation).
Driving off with the test rollers stationary would
damage the mounts of the dynamometer motors.
