How to debug if the weighbridge is not accurate

by admin

when the weighbridge fails to weigh, jump or return to zero, we should keep calm. Many problems can be solved by ourselves, and we don’t need to spend a lot of money to hire maintenance personnel. Therefore, we need to know more about the problem of weighbridge fault

the problem that the weighbridge cannot weigh, jump or not return to zero is generally caused by a variety of reasons. Generally, when we first find that the weight cannot be weighed, we should first check the line to see if the line is damaged due to various reasons: such as crushing, damage, aging, etc., resulting in poor contact; Correspondingly, it is also easy to cause poor contact. It depends on whether the solder joint falls off and whether the sensor main line in the junction box is loose. These often cause poor contact of the whole machine, so sometimes it can read, but sometimes it can’t be weighed, not displayed, skipped or not returned to zero

common problems and debugging methods of electronic weighbridge:

1. Please place the electronic weighbridge on a stable and flat desktop or ground, and do not place it on a shaking desktop or bench
2. Avoid placing in places where the temperature changes too much or the air flows violently, such as direct sunlight or cold air outlet
3. Use an independent power socket to avoid interference from other electrical appliances
4. Adjust the adjusting foot of the electronic weighbridge so that the scale is stable and the bubble in the level is in the center of the circle
5. When the power is turned on, do not put items on the scale. Heat up the engine for more than 15 minutes before use

Mettler provides you with various industrial electronic scales (electronic scales) such as vehicle scale, platform scale, platform scale, counting scale, hook scale, axle load scale, packaging scale, filling scale, batching scale and bulk material scale. It is used in ports and docks, high temperature, magnetic field, factory workshops, trade settlement and other places

It depends on whether the solder joint falls off and whether the sensor main line in the junction box is loose. The whole machine can’t display zero or hour readings, but it can’t display zero, or it can’t contact the whole machine
then, check whether the weighbridge junction box is soaked in water, water or damp, which is often an important factor. If it is found that the weighing is inaccurate, how to deal with the foot difference
nine times out of ten, this is often caused by the deviation and inclination of the underground sensor line on the scale table, or sundries intrude into the scale body and make it stand against the steel plate of the scale body, resulting in collapse. Even worse, it also occurs when the screws on both sides completely stand against the wall. This is often caused by excessive violence and the loosening of the screws after a long time. It can be seen by the naked eye and eliminated after finding it
if there is no such phenomenon, the sensor itself is often damaged. The resistance value of the sensor can be tested with a multimeter and compared with that of other normal sensors to determine whether it is sensor damage. If the resistance value of the sensor changes only in a small range, the adjustable resistance can be adjusted in the junction box to adjust the pin difference. If the resistance value changes too much, the sensor may need to be replaced

 Hello, I'm glad to answer for you ~ I'm talking about emotion with clothes, and I'll answer your questions. I'm typing for you to solve the problem. It takes about 5 minutes. Don't worry. Please wait a moment

 Hello, I'm glad to answer for you ~ 

 method for inaccurate correction of electronic scale: 

 1. First turn on the switch of the electronic scale

 2. After turning on the switch, press and hold the # key until the number 9 is displayed, and then release the # key after three seconds

 3. After releasing, the screen will display D5. If it is not D5, you can press the peeling key to change the number

 4. After the screen displays D5, press the # key to enter the next step. At this time, P0 will be displayed on the screen. If P0 is not displayed, press the peeling key to change the number to P0

 5. After adjustment, press the # key to enter the next step

 6. Press the peeling key to adjust the parameters. After calling up the parameters, press the peeling key to move the position of the red light, where the red light is adjusted

 7. Press the zero key to adjust the number, and then adjust the parameters according to the weight of the electronic scale

 8. Adjust the parameters and press the # key to enter the next step

 9. After entering the next step, press the # key again to enter the next step. The screen will start with AD

 10. Press the peeling key to call up digital parameters

 11. Put the standard legal code. The following figure shows the legal code of 25kg

 12. Press the peeling key to move the position of the red light, press the zero key to adjust the number, and adjust the weight to be the same as the French code

 13. After the steady red light is on, press the # key to enter the next step

 14. Remove the code and put it on the electronic scale. If the weight display is consistent with the code, it proves that it has been calibrated
