As the temperature of the oven that contains the crystal oscillator reaches to the ideal temperature for accurate clock generation, power consumption of the oven decreases and the gauge points to zero, signaling to the user that the digital processing on the connected device is now controlled by an extremely accurate 10MHz clock signal. The gauge is a backlit-type with a dimmer control (including the ability to completely switch the backlight off).\u003c\/p\u003e\n\u003cp\u003e*The oscillator is usually stable about 2 minutes after the power is turned on.
