Three health scales are weighing the use of features in a category (divided into mechanical and electronic), inexpensive, it can help people to effectively monitor their own body weight changes, new products also can detect their fat content, but also Some humanoriented subsidiary functions. May not be part of measuring equipment. 4． Electronic Scale is a measurement of the state pulsory test apparatus, and his qualified products are test indexing the value of D values of e and subdivision standards, is subject to the protection of the national metrology products. In the electronic weighing there is a category called human scale products, which can test in the measurement sector, weighing very precise. Block diagram interpretation of the principle of electronic balance The first part of the electronic scale principle block diagram: Program K / B (button) ↑ Fx → Sensors → OP Zoom → A / D converter → CPU → → display driver display memory Workflow Note: When an object on the pan when the pressure facilities to the sensor that occurred deformation, so that resistance to change, while the use of excitation voltage changes, the output of a change in analog signal. This signal amplification by the amplifier output to the ADC. Converted to facilitate the processing of the digital signal output to the CPU operator control. CPU under the keyboard mands and program output to display this result. Until the show such a result. The second part of the scale of the classification: 1. According to principles of points: Escale mechanical scale mechanical and electrical integration scales 2. According to the functions sub: Counting Scales Weighing Scale Pricing Scale 3. Purpose: Industrial Commercial Scales Special Scales Balance The third part of the scale types: 1. The full name of the desktop Scale refers to the volume of less than 30Kg electronic scale 2. The full name of platform scale refers to the volume within the 30300Kg Electronic Scale 3. Loadometer full name refers to the volume of more than 300Kg Electronic Scale 4. Precision Balance 4th Part of the accuracy of classification: I Class: Special scales precision ≥ 1 / 10 Wan II level: highprecision scale 1 / 10000 ≤ precision of 1 / 100,000 III: the accuracy of scale 1 / 1000 ≤ precision of 1 / 10000 Class IV: Common Scale 1 / 100 ≤ precision of 1 / 1000. Part V of professional terminology: 1. Maximum weighing: an electron balance, excluding tare weight, the maximum load can weigh。 5. permissible error: class test when the maximum deviation。 8. Resolution: a counting function with an electronic scale, the internal capacity of a Resolution of a parameter。 2. To achieve automatic control。 6 . unique features: buckle weight, withholding weight, zero, accumulated, warning, etc.。 10. special industry, can be accessed by the printer or puterdriven。 3. Whether the backlight 。 Part VIII sensor type: 1. Resistive: affordable, high accuracy, widely used。 Display Type: (liquid crystal display): free electricity, energysaving, with backlight。 2. mechani
