Eurosystem / Profi-LON Description
1.6 D1 E101BA1-GB09
1.7.2 Shock Absorber Tester / Suspension
Consists of the functional group SA 2 / FWT 1 Euro and the control module.
SA 2 and FWT 1 are used for judging the condition of a vehicle’s shock absorber..
Selection of the Evaluation Program
Profi-LON: Use this switch for shock absorber measurement to be displayed in
MAHA-Meter or percentage.
Eurosystem: Selection via software.
Single Wheel Program
Profi-LON: Use this switch to start the left or the right-hand test plate. Position “0“
means Standard, i.e. both plates vibrate, one after the other. This function is
suitable for noise detection on the vehicle body or suspension.
Eurosystem offers the single wheel switch over as standard equipment via
software.
1.7.2.1 Measurement Principle
Oscillations of the test vehicle wheels are induced via the test plates. The oscillations run
through various frequency ranges. The reaction of the tire-shock absorber functional group to
these oscillations is recorded.
Amplitude Evaluation Mm
The amplitudes of the measured oscillations at the resonance position are given for each wheel
in MAHA-Meter (Mm).
Percentage evaluation
This evaluation judges the quality of the vehicle’s shock absorber in percentage (%).
