1. Use special cheating tools, the meter can be rigged, and also there's a remote control. 2. You can first try if the weight is the same when the car is on either end of the scale. If it's different, it's easy to handle. Just figure out the position to get on the car. 3. When the car is on the scale, push the scale up a bit. This will increase the weight. 4. Speed up when getting on the car, and brake hard when on the scale. This will make one side appear very heavy (due to the impact force). When the meter hasn't shown the normal weight yet, you can print the receipt (you need to be quick and grasp the timing). 5. You can let the car tires stand on the edge of the scale, half on the scale and half on the foundation. --- The above are the cheating methods I know. I don't know your specific requirements. For Taian Logistics, the best cheating method seems to be buying a riggable display meter, which can be altered as desired. It appears that cheating devices aren't very effective, they're just misleading people. Scales can be classified by sensor output signals into analog scales and digital scales; by weighing methods into static vehicle scales and dynamic scales; by installation methods into above-ground scales and underground scales; by platform structure into steel-structured platforms and concrete platforms; by usage environment into explosion-proof scales and non-explosion-proof scales; by automation degree into non-automatic scales and automatic scales. In recent years, with the continuous improvement of enterprise management levels, unmanned automatic scales are becoming the future development direction of scales.
