The accuracy of the portable electronic truck scale is very high in the static weighing state. For example, the weight is very accurate when the weight is directly placed on the scale platform in the static state. However, in the actual weighing process, the car slowly drives the weighing platform, which belongs to dynamic weighing. In the dynamic weighing state, because everyones driving habits, speed and the point of force passing through the weighing platform are different, the weight of each overweight will be different to different degrees, because the following items will be noticed in the actual weighing operation process to reduce the error as much as possible Lower.

  1. When the portable electronic truck scale is used, the ground shall be hard and flat: when weighing, the scale platform must be placed on the flat and hard cement or asphalt road side by side, and it is not allowed to put in the uneven stone road or soft soil air, and the two weighing plates shall be placed in parallel, not one before and one after.

  2. The distance between the left and right of the weighing platform and the left and right of the wheels of the portable electronic truck scale is different: the distance between the left and right of the wheels of different models of vehicles is different, so before weighing each time, the left and right of the weighing platform should be adjusted to conform to the distance between the left and right of the wheels of the weighed vehicle, so as to ensure that each wheel can be pressed on the weighing platform plate when the wheels of the vehicle pass through the weighing platform successively, and the vehicle The past time of wheel rolling shall be pressed in the middle of the weighing plate as much as possible, because the more the stress point is close to the center of the weighing plate, the higher the accuracy is.

  3. When the portable electronic truck weighbridge weighs, the car shall weigh in a straight line and slowly at a uniform speed: the car shall pass through the weighbridge in a straight line, but shall not turn to the weighbridge, and shall pass through the weighbridge at a uniform speed of less than 5 kilometers per hour. The speed must be slow and uniform, and shall not be faster or slower. Because the speed and stability have a great impact on the accuracy of weighing.

  4. Place selection of portable electronic truck scale: the road before and after the weighing of portable electronic truck scale shall have a flat position corresponding to the wheelbase length of the weighing vehicle, and there shall be no up and down slope or sharp bend. 

  5. Portable electronic truck scale is not suitable for embedded fixed use: portable electronic truck scale is designed for the convenience of carrying and moving, and the scale platform is designed to be relatively thin and small in area. When weighing, the portable electronic truck scale is placed on the ground so as to move and adjust the distance between the positions when weighing, instead of digging a pit like a fixed scale to fix the weighing platform plate into the ground, so as to It can cause insufficient compression gravity. Secondly, it is impossible to adjust the position of the left and right force points according to the different wheel spacing, so as to form a great weighing error.
