    • Disclosed is a method for determining the resonance frequency of an electric resonant circuit, specially a starting resonant circuit for high-pressure gas discharge lamps, wherein the resonant circuit is excited with various frequencies. The frequency search is carried out in a search run with individual sampling tests, wherein a set, invariable frequency is used. Each invariable frequency is selected and used according to a determined search scheme. The fist sampling test is carried out with a mean frequency (fmitt), whereby the mean frequency of the mean value is the possible minimum (fmin) and maximum (fmax) resonance frequency. The test frequency is modified in steps (+-n* DELTA f) for each subsequent sampling test. The resonance frequency found in a search run can be stored or optionally renewed as a learning frequency (flern) for use as a starting frequency in subsequent search runs. In an advantageous embodiment provided by the invention, the frequency search is conducted using a voltage, which is below the starting voltage, the current is measured in the resonant circuit, the maximum value of the current measured is determined and the resonance frequency occurring at maximum current is given.
