Abstract
A detection device for detecting an oscillator is provided. The detection device includes an oscillator control circuit, a frequency-decreasing circuit and a display circuit. The oscillator control circuit is used for outputting the oscillator signal of the oscillator. The frequency-decreasing circuit is connected to the output of the oscillator control circuit and has a capacitor suitable for charging and discharging and a resistor, which can adjust the time constant of the oscillator signal. The display circuit is connected to the frequency-decreasing circuit for showing the output signal of the frequency-decreasing circuit. The detection device can decide whether the oscillator is normal or broken by observing a component of the display circuit, for example, the twinkling of a light emitting diode of the display circuit.
