AN APPARATUS AND A METHOD FOR ADJUSTING TEMPERATURE COMPENSATED QUARTZ OSCILLATOR.

Application 886/MAS/1998 published 2006-10-20, filed 1998-04-24
The invention relates to an apparatus for adjusting temperature compensated quartz oscillator device, said quartz oscillator device having a variable capacitor, a storage device, and said quartz oscillator on which a temperature characteristic informatiop 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 capacitor, the measured temperature of said quartz oscillator being stored in said storage device; and a 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, having 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.
