1. A checker for simulating the test parameters of a sensor and tone wheel associated with an anti-skid system;
- said checker comprising;
generator means for generating a signal simulating the rotational velocity of said tone wheel, the output frequency of the generator means representing said rotational velocity;
level changer means for controlling the output frequency of said generator means;
electric control means receiving the output of said generator means over an impedance;
means for selectively shorting at least some of said impedance;
and means for selectively preventing said generator means from providing an output above a predetermined frequency.

Abstract
A system for simulating the parameters tested by a testing device is described. The testing device is used to verify that a sensor and tone wheel of an anti-skid system are properly functioning and connected. Accordingly, the testing device is used to check the resistance of the sensor, the level and frequency of the output voltage from the sensor, and whether the tone wheel has any missing teeth or is improperly aligned with respect to the sensor. The invention is directed to a system for simulating all these parameters to verify that the testing device is functioning properly.
