Electronic scales are a type of weighing instrument that utilizes Hooke's law or the lever balance principle of force to determine the mass of an object. Electronic scales are mainly composed of load-bearing systems (such as scales, scales), force transfer system (such as the lever force transfer system, sensors) and the value system (such as dials, electronic display instrument) 3 parts. According to the structural principle can be divided into mechanical scales, electronic scales, electromechanical combination of three major categories of scales.
Electronic scale is a national compulsory verification of measuring instruments, his qualified products are calibrated index value e and subdivision value D of the standard, is protected by the National Measurement Law products. In accordance with the "Chinese People's *** and State Measurement Law" and "Chinese People's *** and State Compulsory Certification of the work of measuring instruments directory" requirements, all as a social public standard of measurement of electronic scales, departments and enterprises, institutions use for the highest standard of measurement of electronic scales, and for trade settlement, safety and security, medical and health care, environmental monitoring aspects of the electronic scales, in the use of prior to the metrological verification are required to Qualified before use. Not in accordance with the provisions of the application for metrological verification, or by the unqualified, not to be used.

Waterproof Scale
With the development of electronic scales, and the needs of special applications, waterproof scales came into being. Waterproof scales, as the name suggests, can be waterproof. Waterproof scales vary in waterproof performance depending on the level of waterproofing. Xiangshan waterproof weighing scales have the highest waterproof level of IP68, and can be weighed even when soaked in water.
The internal sealing structure of the waterproof scale prevents corrosive liquids and vapors from corroding the elastomer of the sensor, which greatly improves the life of the sensor. The purpose of the waterproof scale is waterproof and moisture-proof to cope with those harsh environments such as humidity and salt spray. Waterproof scales are generally divided into waterproof price scales, waterproof weight counting scales, waterproof electronic platform scales and so on.
Waterproof pricing scales
Waterproof design on the basis of the original pricing scales, the internal scale structure re-designed according to the waterproof level. The external weighing pan, power cord interface, switch, etc. are all redesigned.
Waterproof weighing scales
Waterproof weighing scales are certified to be waterproof in all dimensions, with a large window, super anti-slip and anti-drop, and are designed for the harsh environments of cold storage. Suitable for aquatic processing, seafood processing, fishery production and so on.

9. Simple installation and calibration;
10. Special industry, can be connected to a printer or a computer driver;
11. Intelligent electronic scales, fast response, high efficiency;
1. Maximum weighing capacity: one electronic scale, regardless of Maximum weighing capacity: the maximum weighing capacity (full load value) of an electronic scale without tare, i.e., the largest load that can be weighed;
2. Minimum weighing capacity: a relative error that will occur when an electronic scale is below this value;
3. Safe load: 120% of the normal weighing range;
4. Rated load: the normal weighing range;
5: The maximum permissible deviation when the grade is calibrated;
6. Sensitivity: the smallest scale that an electronic scale can display; it is usually expressed by "d";
7. Minimum Scale: the starting value, e.g.: 60Kg×5g, 5g is the smallest scale, i.e., the minimum sensibility;
8. Interval of Scale Scale interval: if the scale starts from 10g, every 10g is a scale until the maximum weight **** for how many scales,
for example: 100kg×10g, (100×1000)÷10=10000, 10000 is the scale interval,
For example: 100kg×10g, (100×1000)÷10=10000, 10000 is the scale interval,
This is the minimum scale. 10000, 10000 is the number of scale intervals;
10. Precision: the ratio of the sensibility to the total weighing capacity. For example: weighing 6000g minimum scale (sense) 0.5g, that is, 05/6000 = 1/12000 1/12000 that is, the precision of this scale;
11. Electromagnetic interference: radio waves generated by the interference commonly known as, for example: big brother cell phone sent out by the radio waves.
12. Resolution: an electronic scale with counting function, the smallest scale that can be defended;
13. Resolution: an electronic scale with counting function, a parameter that has the ability to defend internally;
14. Internal Resolution: the internal precision, such as the 5 COUNT 1 jump, then the 5 COUNT that is, the internal resolution,
15.For example: 100g (scale weight) × 0.01g (sense), 5 COUNT 1 jump, 0.01g ÷ 100g = 1/10000 (precision),
1/10000 ÷ 5 = 1/50,000 (internal resolution), the internal resolution is mainly for the CPU to do the arithmetic.
The internal resolution is mainly used in counting scales, which is simply the minimum value that can be counted and analyzed by Counting Scale.
15. Warm-up time: the time taken for a scale to reach each of its targets;
16. OFFSET value: the value taken from COUNT as the zero point value for the start-up of the scale, which is mainly used to keep the scale in normal operation, in order to avoid any improper situation from occurring. (COUNT: refers to the internal analysis value) General scale in the setup, by the software people on the model of the scale definition - OFF SET value, that is, the zero point value, can be adjusted when the judgment and basis.
17. SPAN value: Put the load on the scale to display the value, that is, SPAN, so that the scale puts how much weight on the display of how much weight, so that the scale does not have too much error.
18. Creep CREEP: After a time load test and record the results to see if there is any change in the results of the test, the size of the CREEP
will determine the stability of the scale.
19. Hysteresis: Take the weights of equal proportion and place them on the scale and record the displayed weight, then remove the weights from the scale in equal proportion to see if there is any error,
somewhat similar to the Q15 measurement of linearity, to test whether it is a good response.
20. Applicable temperature: -10℃~+40℃. (According to the definition of OIML, if the applicable temperature is not indicated, it will be based on this).
21. Humidity: the relative percentage of water in the air, too high humidity will affect the scale's linearity and stability, too low, too dry will produce static interference.
22. The ambient temperature for electronic scales is: -10℃ to 40℃
23. The table specification of desktop scales: 25cm X 30cm 30cm X 40cm 40cm X 50cm 42cm X 52cm 45cm X 60cm
Two common troubleshooting solutions for electronic scales:
Electronic scales are unable to charge or the charging indicator does not light up or there is no response. Charging indicator does not light up or does not respond
1. Please make sure that the 110V/220V voltage switch of the electronic scale is adjusted to the same voltage as the power supply, and make sure that the charging cable is firmly inserted into the charging seat on the scale.
2. Check if the charging cable is disconnected due to external factors.
3. Check for a bad fuse.
4. Bad battery.
5. For reason #4 or other factors not mentioned above, it is recommended to return to the dealership.
6.
