What are the precautions for the correct use of electronic truck scale?

The correct use of electronic truck scale matters needing attention 1, electronic steam balance after the local juice department verification can be used, shall not destroy the electric car heng seal, shall not be replaced on the system parts, adjustment, shall not easily change the system Settings. 2, electronic truck scale failure, should immediately stop using, report to the relevant departments to cooperate with the number of industry maintenance personnel to check and repair, and qualified after inspection can be used. 3, electronic truck scale should be used and maintained by full-time weighing device operator, weighing device operator must be specially trained, hold the qualification certificate can be engaged in operation and maintenance. Operators should be familiar with the technical performance of electronic truck scale, operation method and key points of use, and should be more skilled in dealing with the problems on site. 4, before use should check whether the wiring loose, broken, grounding wire is firm. Before use, the instrument will start up and preheat for about 30min. After the instrument is powered on, it will conduct self-test or press the self-test switch for self-test. After proving that the system is normal, it can be weighed. 5. There shall be no stone, coal and other foreign bodies stuck in the clearance around the platform. The platform and the limit bolt around the platform shall not collide and friction. 6, the vehicle driving I shenyang F platform should be straight line, the speed is less than 5 km/h, and then gently brake, and as far as possible to stop in the center of the platform, the car stop stability after weighing. The total weight of the vehicle should not exceed the maximum weight of the electronic steam scale, so as not to damage the parts. After weighing, the vehicle drives off the scale platform and checks the empty scale. Only after confirming that the weighing display instrument returns to zero can the weighing result be identified as valid. After the weighing, the power supply of the weighing display instrument must be cut off when the weighing fails for a long time to avoid burning and damaging the components. 7. It is forbidden to conduct arc welding on the weighing platform. Scale platform and around should be kept clean and dry, to prevent water and other debris pollution, the special channel is the junction box should be dry, desiccant box to be replaced regularly. In order to prolong the service life, necessary anti-corrosion measures are taken for the weighing sensor.
