The circumference of the measuring roller (the
roller upon which the roller sensor is mounted) is
calculated automatically.
For the steps involved in this measuring process,
see the
Chapter entitled “Automatic roller
on
Page 32
.
Note:
Wheel circumference measurement is always
carried out without the correction value (which is
set with ).
Roller direct
The circumference of the measuring roller (the
roller upon which the roller sensor is mounted)
and the number of pulses per measuring roller
revolution are entered in the CTC II.
In the case of the double roller set, a roller
circumference of 1000 mm and a pulse count of
100 imp/ rev must be entered.
Roller circumference
100 … 5000 mm
Measuring roller circumference input in mm
Pulses
10 … 999
Input of the imp/ rev of the measuring roller/
number of teeth
Length measuring track
20 … 10000 m
Entering the length of the measured track to
determine the W value and the vehicle
constants.
The default value is predefined by the setting of
the test stand type:
•
20 m for the brake test stand,
•
200 m for the rolling road test stand.
Number wheel turns
3 – 20
Input of the number of wheel turns during wheel
circumference measurement (L value)
Default value: 10
Min. test speed
1 … 80 km/h
Minimum test speed input
The test functions start when roller speed is
greater than the minimum test speed.
During the test, a cyclical check is carried out to
ascertain whether or not the value is under-run.
If the value is under-run, the CTC II aborts the
test.
Default value: 1 km/h
Max. test speed
1 … 80 km/h
Maximum test speed input
The test functions start when roller speed is less
than the maximum test speed.
During the test, a cyclical check is carried out to
ascertain whether or not the value is exceeded.
If the value is exceeded, the CTC II aborts the
test.
Default value: 80 km/h
