Abstract
PURPOSE:To perform the adjustment of frequency correctly by providing a temperature visible indication means at a casing to perform a visible indication, thereby directly indicating a casing temperature of electronic components. CONSTITUTION:A casing 2 of a crystal oscillator 1 is provided with a label 3 at its upper face end part and the label 3 is applied with a coating, colors of which vary with the change of temperatures, for example, the colors at temperatures ranging around 25 deg.C+ or -2 deg.C are different from those at the temperatures other than above figures. An upper part of the casing 2 is equipped with a trimmer capacitor 4 where its capacity can be changed and oscillation frequencies of crystal oscillator 1 is variable. When the oscillation frequencies of the oscillator 1 are adjusted, it is necessary to wait the change of colors at the label 3 after adjusting a temperature in the room where the crystal oscillator is placed. While the colors of the label 3 change, frequency adjustment is carried out by turning the part of adjustment screw of the trimmer capacitor 4. Even when frequency adjustment is performed by service shops or users, it is possible for them to perform frequency adjustment correctly without watching a thermometer.
