Abstract:
An apparatus for adjusting a temperature compensated quartz oscillator device, said quartz oscillator device having a variable capacity element, a storage device, and a quartz oscillator on which a temperature characteristic information thereof is displayed, said apparatus comprising:a frequency adjusting device having a temperature sensor for measuring a temperature of said quartz oscillator at a time when a frequency of said quartz oscillator is adjusted to a predetermined frequency by said variable capacity element, the measured temperature of said quartz oscillator being stored in said storage device; anda temperature-compensating-data writing device having means for reading the displayed information, and a plurality patterns of standard temperature-compensating-datum, said temperature-compensating-data writing device being operable to select temperature compensating data optimally suited to the displayed temperature characteristic of said quartz oscillator which has been read by said reading means, and means for calculating a frequency deviation caused by a difference between the temperature of said quartz oscillator at the time of adjustment thereof and a standard temperature, said writing device is also operable to store the temperature compensating data, including the frequency deviation, in said storage device,wherein the temperature characteristic of said quartz oscillator is compensated on the basis of the temperature compensating data corrected for the frequency deviation.
