Changzhou Yubo Electrical Manufacturing Company has produced and sold a variety of weighing instruments for many years, such as weighbridge, weighing instruments, etc. The following Xiaobian is about the company's product electronic scale. What should be done when it fails?The electronic scale cannot be charged or the charge indicator is not bright or responsive1. Please determine the 110V/220V of the electronic scale first. Whether the voltage switching switch is adjusted to the same voltage as the use of the power supply, and make sure that the charging cable is firmly plugged into the charging dock on the scale.2. Check whether the charging cable is disconnected due to external factors.3. Check whether the fuse is faulty.4. The battery is faulty.5. For 4 reasons or non-above mentioned factors, it is recommended to return to the distribution station for processing.No action after the electronic scale is turned on?1. If you use a dry (storage) battery, please check whether the voltage of the dry (storage) battery is sufficient. If the voltage is insufficient, replace the dry battery (charge the battery).2. If you use the ADAPTOR, pull out the ADAPTOR output terminal connected to the electronic scale, and then install the dry battery. If it can be turned on, that is, the ADAPTOR is damaged, please replace it.3. Whether the fuse of electronic scale is bad.4. The switch or key may be damaged.5. The electronic component may be faulty.6. For 4 or 5 reasons or not mentioned above, it is recommended to return to the distribution station for processing.The above is the company about the failure of the electronic scale to do some of the handling methods, I hope to help you, the company also welcome you to inquire about the purchase.

The structure, accuracy, stability, surface treatment, anti-corrosion, waterproof, explosion-proof and application in special industries have unique industry advantages, and have obtained a number of national patents. Do you know how to repair a truck scale when it breaks down?1, the small tonnage loading display is normal, close to 1/2 weight, the weighing value shows a sudden increase. This phenomenon is mostly caused by the gap between the longitudinal limit bolt and the roof is too small. When the load increases, the longitudinal bolt supports the roof, resulting in direction finding jacking force, which causes the display value to suddenly increase.2, small tonnage loading is normal. After the load is increased, the display value is obviously reduced, which may be due to the contact between the weighing sensor shield and the weighing platform or the improper adjustment of the load limiting device of the weighing sensor, so that the weight cannot be fully added to the weighing sensor.3, there is heavy weight on the scale, but the display is still "zero", the possible reasons are:The function key of the weighing display controller is used incorrectly and is not in the weighing display state. It may be that the total output line of the load cell is not in contact with the connector of the load cell4, the scale shaking is not flexible, the ballast does not match the display. There is filler in the gap between the scale body and the slope protection (or between the scale pit), so that the scale platform and the ramp (or pit) are connected, affecting the weighing.5, the display value after loading is much lower than the load value. Generally, the excitation power supply of the load cell fails.6, after power, the display flashes a fixed font, no measurement. Generally, the output signal of the weighing sensor is shorted with the shielding layer, so that the weighing display controller inputs a large signal and there is overload. The resistance value between the sensor and the shielding layer and the ground wire can be measured with a multimeter to find out the short circuit.7, the printer does not turn, can not work. The printer connector is not good.Over the years, the company has insisted on bringing good service and products to you, and welcome new and old customers to inquire and buy.

Some customers responded that the weighing of the truck scale bought back was not accurate enough, and it was also according to the installation diagram given by the manufacturer. Today, Changzhou Youbao will talk about what factors will affect the weighing results of the truck scale?1. The impact of the installation base on accurate weighingThe installation of the foundation for the accurate use of Qingdao weighbridge has a very important position, is the so-called tall buildings from the ground, if there are problems with the installation of the foundation, it is impossible to have the normal and accurate use of weighbridge, the accuracy of weighing will inevitably be affected, the installation of weighbridge should first have a more suitable and spacious site, and should ensure that the foundation has a larger bearing capacity. The height of the focus must be on the same level.2. Carrier structure designWeighing platform as a force surface of the truck scale, its structure and design should meet our expected purpose of use.Any truck scale installed in a fixed position, its foundation and related components should be able to provide a certain strength, stiffness and stability, and there should be gaps around the moving parts, no contact influence in the unloaded truck scale and the entire weighing range, to ensure its metering performance during the service life.In addition to the above two points will cause the inaccurate weighing data of the truck scale, the sensor will also affect the data, you are welcome to consult our company to learn more about the factors that affect the scale data.

Common electronic platform scale fault problems and solutions:1, boot without any display, sound: from the circuit analysis, "no display" is the fault of the display circuit, no sound is the fault of the buzzer circuit. The probability of the two faults occurring at the same time is very low. So the general fault occurs in the power supply circuit.2. Weight is not allowed: Observe whether there is friction in each part of the sensor, whether the stabilized power supply is stable, and whether the operational amplifier circuit is normal. Whether there are foreign bodies on the circuit board of A/D circuit.3, poor display: boot to observe whether there are bad conditions on the normal LCD, if not, it can be determined that the LCD is bad; Check CPU connectors for oxidation, cold welding, or short circuit. Check whether there is short circuit between the CPU and the LCD.4, the battery can not store electricity: first determine the fuse, power switch, power line caused by the problem; Check whether the transformer has AC110/220 input and AC18V output; Check whether the diode of the PIN attachment at the input end of the transformer is normal; Replace the battery.5, the electronic can not charge or the charging indicator is not quantity or no response: please first determine whether the electronic 110V/220V voltage switch is adjusted to the same voltage as the use of the power supply, and determine that the charging line has been firmly inserted in the charging base on the scale; Check whether the charging cable is broken by external factors; Check whether the fuse is bad; The battery is faulty.6, the key no action or action is often automatically triggered: the key is bad; Key socket is faulty.7, electronic said can not be weighed to full load: electronic said protection screw is not removed; Electronic said whether there is foreign body infiltration caused interference or impact, fall injury; Whether the internal procedure Settings of the electronic scale are correct.The above is Changzhou Youbao for you to share a few points about the electronic platform scale fault phenomenon and treatment, welcome to pay attention to our official website.
