The pre-treatment method for an electromechanical transducer is particularly suitable for polarizing a piezoelectric actuator for an injection system of an internal combustion engine. Prior to the actual operation, the transducer is actuated with an electrical pre-treatment signal, in order to set a predefined operating point in accordance with the pre-treatment signal. The pre-treatment signal corresponds substantially to the electrical actuation signal during normal operation of the transducer, in order to prevent a displacement of the pre-set operating point during normal operation of the transducer.
