How to repair the bicycle codes of the bicycle codes, common fault checks of bicycle codes

Common fault inspections and maintenance of bicycle code tables

1. Check whether the distance between the magnet and the induction switch meets the requirements. If the distance is too far away, it will affect the accuracy of the speed.

maintenance method: adjust the distance between the magnet and the induction switch to the right distance.

2. The contact point of the code watch and the circuit on the seat is dirty, causing poor contact.

maintenance method: Use fine sandpaper to polish.

3. Check whether the connection line of the induction switch to the code table has internal disconnection, resulting in intermittent interruption.Checking method: Dial the multimeter to the "RX1" file, and the red and black surface needles are connected to the two electrodes on the codes. At this time, the front wheels should be turned, and the pointer of the multimeter should be swinged left and right.

maintenance method: The induction switch is normal and the connection is normal; if you do not swing or dial the line gently, the intermittent time is open, there is a breakpoint of the connection, and the connection line needs to be replaced.

4. The above are normal. Please check whether the battery of the code watch should be updated?Using the universal DC voltage V10, the battery voltage for various tables may be different.

maintenance method: As long as the measured voltage is below 60%of the original battery voltage, the battery needs to be replaced.For example, the LR44 twist battery should be 1.5V. If the measured is & lt; 1.0V, the same type of battery needs to be reduced.

5. The code watch may enter the water, causing internal line failure.

maintenance method: Open the rear cover and put the code watch for about 30 minutes at 10-20 cm from the incandescent lamp, but pay attention not to be too close, due to the high temperature damage circuit.

6. If the LCD screen of the code watch is black.

maintenance method: It means that the code watch is damaged, then you need to change the new watch.

7. Because the magnetic body of the bicycle watch is installed on the barrier, it is often in a fast rotation state, and it is often easy to change or even fall off due to touch, collision, and rubbing.

maintenance method: If it is lost, it can be self -made.The method of repairing the bicycle code is as follows: Find a small magnet (such as a magnetic door touch and a small magnet in the Headset, with small size, strong magnetic force, light weight light), a small aluminum Skin, a bottle 502 502Powerful glue. First cut the small aluminum Skin with scissors to 15X20mm; Then fold it on the position of the bar that needs to be installed (form a U -shaped); Inject an appropriate amount of "502" glue in the middle of aluminum Skin and magnets, so that the magnets and aluminum Skin are firmly stuck (about a few minutes); Adjust this magnet up and down to the right position, and inject "502 ".After drying, adjust the position and position of the induction switch, that is, the sue is successful.
