The reason why quartz clock is slow.

1. The quartz watch battery is dead or has insufficient capacity, so it needs to be replaced with a new battery. However, the analog electronic watch often finds that the battery is dead in a short time. Professional and technical personnel pointed out that this situation is generally caused by high power consumption or low quality of the battery itself. If the quartz watch battery is dead or the capacity is insufficient, the watch will slow down, so just change the battery. ?

2. The stepping motor cannot rotate. The rotor of stepping motor is a permanent magnet, which often sticks to the stator due to the adsorption of iron filings, causing the hands of quartz watches to stop or stop when walking. ?

3, gear train failure, most of them are dust and foreign matter between gear teeth, which makes the gear train teeth stuck to each other. So are some tables? Too much or too little oil, too much oil causes adhesion between wheels and between wheels and splints. Too little oil makes the resistance of the rotating gear train too great, which will make the electronic watch difficult to use. Encounter these faults of stepping motor and gear train? Clean everything, remove foreign bodies and come on. ?

4, poor contact, mostly dirt on the positive and negative contact reeds, poor contact with the battery. The contact between the signal output point on the circuit board and the lead-out point of the coil head will also cause poor contact. All these will cause the circuit to be non-conductive, so that the electronic watch can't work or work well. If it is found that the circuit is blocked due to poor contact, the contact surface should be thoroughly cleaned before reassembling. ?

5, coil open circuit, due to oxidation or human reasons, make the coil damage, can be detected by multimeter test, generally need to be replaced. ?

6. The quartz watch has no output signal, so check that all other aspects are normal. Check the circuit board with a multimeter, and see that there is no 1 signal, mostly because the oscillator is damaged or the integrated circuit is faulty. If replacing the oscillator is ineffective, the whole circuit board needs to be replaced. ?

More than 80% of quartz watches are slow due to insufficient battery power, so it is very important to replace the battery in time. Please go? Replace the battery of the corresponding model at the professional maintenance point. The watch battery is low and needs to be taken out in time. If you put it in a watch, it will easily lead to battery expansion, leakage and pollution of the watch, which will be very troublesome to maintain.

Extended data

Quartz clocks and remote controllers with low power consumption should use P-type carbon batteries. But if you want to prolong the service life, it is better to use alkaline batteries, because the power of alkaline batteries is 4-7 times that of carbon batteries, such as Changhong alkaline batteries. Because the shell of carbon battery is a zinc tube as a negative electrode, it will participate in the chemical reaction of the battery, so it will definitely leak after a long time, and it will leak after a few months of poor quality. The shell of alkaline battery is steel, which does not participate in chemical reaction, so alkaline battery rarely leaks liquid, and its shelf life is more than 5 years. So you don't have to worry about leakage if you use alkaline batteries for a long time.
