Abstract: A shock absorber testing instrument with electronic units for recording vibrating movements of the vehicle body and for signal processing and assessment, including at least one sensor, preferably a piezo-sensor or a micro-sensor for signal processing and assessment of the data collected. The instrument also includes at least one measured value amplifier and a microprocessor, as well as a keyboard, a display unit and several suitable interfaces to connect other peripheral devices, which preferably are integrated in the instrument.

Abstract: A shock absorber test unit is provided, including a housing attached to an automobile body by magnets. The housing has a mass, such as a permanent magnet or coil, which swings with damped oscillations due to inertia. The number of oscillations is counted and indicated on a digital display on the housing via an inductive oscillation sensor attached to the interior of the housing after a jolt of the automobile.
