<p>The present invention relates to a method of adjusting the frequency of a coupled monolithic quartz. This method consists in constructing in one go a base metallisation, then detecting the frequency transmission curve for the quartz which is short-circuit configured; by using this curve, the high and low frequencies of the quartz (FH, FB) are measured at a given instant and the balance is checked; the high and low frequencies are compared with the frequencies to be obtained and the result of the comparison is sent as a command for the metallisation masks, the operations of measuring and of comparing the frequencies being restarted until the desired values are obtained, balance being checked each time. <IMAGE></p> |
