1. Maximum weighing: The maximum weighing capacity (full load value) of an electronic scale does not count the tare weight, that is, the maximum load that can be weighed;

2. Minimum weighing: a relative error that will occur when an electronic scale is lower than this value;

3. Safe load: 120% of normal weighing range;

4. Rated load: normal weighing range;

5. Allowable error: the maximum allowable deviation during level verification;

6. Sense: the smallest scale that an electronic scale can display; usually expressed by "d";

7. Minimum scale: Take-off value, for example: 60Kg×5g, 5g is the minimum scale, that is, the minimum inductance;

8. Scale interval: Sensitivity = (e ), which means how much weight will be added for each jump, for example: 300g×0.001g, 0.001g is the sensation;

9. The number of scale intervals: If the scale starts from 10g, every 10g is a scale until the maximum scale is how many scales,

For example: 100kg×10g, (100×1000)÷10=10000, 10000 is the number of scale intervals;

10. Precision: The ratio of the inductance to the full weighing. Example: The minimum scale (sensing capacity) of 6000g is 0.5g. That is, 05/6000=1/12000 1/12000 is the precision of this scale;

11. Electromagnetic interference: The interference caused by radio waves is generally called, for example: the radio waves emitted by big brothers and big mobile phones.

12. Resolution: An electronic scale with counting function, the smallest scale that can be distinguished;

13. Resolution: An electronic scale with counting function, a parameter with resolution capability inside;

14. Internal resolution: the internal precision, such as 5 COUNT 1 jump, then 5 COUNT is the internal resolution,

For example: 100g (weight) × 0.01g (sensitivity), 5 COUNT 1 jump, 0.01g÷100g=1/10000 (precision),

1/10000÷5=1/50000 (internal resolution), the internal analysis is mainly used for calculation by the CPU.

Internal resolution is mainly used in counting scales, which is simply the minimum value that Counting Scale can count and analyze.

15. Warm-up time: the time it takes for a scale to reach various indicators;

16.OFFSET value: Take a value from COUNT as the start-up zero value, which is mainly to keep the scale in normal operation to avoid improper situations. (count: refers to the internal analytical value) When setting the general scale, professionals will define the -OFF SET value for the scale of the model, that is, the zero point value, which can be used for judgment and basis during adjustment.

17.SPAN value: Put the load on the value displayed on the scale, that is, SPAN, so that the scale will display the weight as much as the weight is placed, so that the scale will not have too much error.

18. Creep CREEP: After a period of time load test and record the result, see if there is any change, the result of the test, the size of CREEP will determine the stability of this scale.

19. Hysteresis: Take the weights of equal proportions and place them on the scale and record the displayed weight, and then remove the weights on the scale in equal proportions to see if there is any error. Is a bit similar to Q15 measuring linearity, to test whether its resilience is good.

20. Applicable temperature: -10℃~+40℃. (According to the definition of OIML, the applicable temperature is not indicated on this basis).

21. Humidity: The relative percentage of moisture in the air. Too high humidity will affect the linearity and stability of the scale, and too low or too dry will cause electrostatic interference.

22. The ambient temperature of the electronic scale is: -10℃ to 40℃

23. The table size of the platform scale: 25cm X 30cm 30cm X 40cm 40cm X 50cm 42cm X 52cm 45cm X 60cm
