What are the faults in the verification of the zero accuracy of the electronic scale? Do your friends know? Today, I will give you a detailed summary of the problems that are likely to occur in the verification of the zero accuracy of the following electronic scales. I hope I can help you. According to my research, the verification of the zero accuracy of electronic scales is generally as follows: electronic scales * methods: take the accuracy of the zero-setting device to complete the verification of the zero-setting accuracy of the electronic scale. First, we will set the electronic scale to be tested to zero, and then we can increase the weights one by one, it is an electronic scale with zero tracking with automatic zero setting. It will get rid of the zero tracking range (Such as adding a weight of 10e)The zero error is measured by the flicker point method. The second method: the accuracy of the skin removal device is adopted to complete the verification of the zero setting accuracy of the electronic scale. This step is the same as the previous step, and the accuracy of the skin removal device of the electronic scale is determined first, the indication value of the skin removal device should be adjusted to zero, and the error should be measured by Flicker point method. The electronic scale is set to zero. For example, verify that the dividing value of an electronic scale is 50 kg, pre-test the skin removal accuracy of 10t tare weight, how to carry out the test, and add a weight of 10t to the scale platform, press the skin removal key, the indicated value is 0 kg, and then 0. 1e = 5kg small weight, when added to weight, is displayed, and the calculation zero error = 25-35 =-10 kg. The peeling accuracy of the weighbridge is-10 kg. According to the * allowable error judgment, the accuracy of the skin removal device should be-0. 25e =-12. 5 kg, the accuracy of the weighing device is qualified. The accuracy of the electronic scale, the above is only the verification method of the zero accuracy of the electronic scale. Therefore, in real life use, the cost should be comprehensively considered according to the actual use of electronic scales, the system should be reasonably designed, and a more economical and suitable weighing and metering scheme should be selected. According to the actual situation, it is necessary to achieve the goal of more economical and optimized. Shenzhen ptksai Technology Co. , Ltd. was founded in 2009.
