I am afraid of being missing two less when I go out to buy things? Take a portable electronic scale! Practical electronic scales are very accurate, simple and practical, easy to carry, low cost, accurate measurement, and cheap price.It is the first choice for family shopping.
Practical electronic scales are not allowed
Reasons for inaccurate electronic scales 1. Reasons for new purchase of hand -in electronic scale 1) Check whether the bottom transport protection at the bottom of the bottom is removed;Whether there is a impact in it causes the sensor to be damaged.2. Reasons and methods: 1) If the weight is more, you can take it down and put it in again.The counting accuracy of counting scales and heavy scale is determined by the accuracy of the sampling calculation of the single weight. Therefore, the selection and operation of counting scale and heavy scale should be paid to the following:
How much is a portable electronic scale
1. High -grade electronic scale: the scale of vegetables, the glass surface of the weight, a portable scale, etc. The price of this electronic scale is 60 ~ 300 yuan.Repeatability], suitable for collective weighing is use.2. Mid -range electronic scales: measurement, counting electronic scales, and accurate titles of [III] in accordance with national measurement specifications.The quality of the goods is normal, and it is appropriate to use the use of [trade, corporate measurement].The price of this electronic scale is 600 ~ 1,000 yuan.3. High -precision electronic scales: It really only needs to be called electronic scale is the title [III] accurate titles. The real high accuracy should be called Tianping [III].This type of electronic scale has a high degree of scores, and the accuracy of [III] of the electronic table scale is still the accuracy of the electronic table scale, and the test score value E = 10D.Users can see a small degree of showing points.This electronic scales are used in the use of scientific research and workshops, and can not be used as a trade budget.The price of this electronic scale is within 1,000 to 2,000 yuan.
Practice electronic scale principle
The electronic scale belongs to the type of the balance of the balance.The electronic scale is mainly composed of three parts: load -bearing system (such as a scale, a scale), the transmission power conversion system (such as lever transmission system, sensor), and the display value system (such as scale disk and electronic display instrument).According to the principle of structural principles, it can be divided into three categories: mechanical scale, electronic scale, and electromechanical combination scales.
Practice electronic scale repair
1 Do not return to zero (not zero, not weigh) a check whether the output signal value of the sensor is within the standard.(A/ds total size/use inner code range/bottom code range) B is not within the standard, please refer to the tenth project for compensation.c, please check whether the sensor is not good if it cannot be compensated.(Please test according to items eighth) D, please correct weight according to the instructions.2 The weight is not allowed to observe whether the inner code value is stable, whether there is friction in each part of the sensor, whether the stable power supply is stable, whether the op amp circuit is normal, whether the line version of the A/D circuit has a foreign body, the feedback resistance/capacitor/filteringWhether the capacitance is poor or leakage.B check whether the signal value of the sensor output is within the standard.C is not within the standard, please refer to the tenth project for compensation.D Test whether the volume of the four -legged scale is average.(If you are uneven, please refer to the ninth item.) E should be corrected according to the instructions of the instructions.
Which brand is good?
