Firstly, accuracy reflects the similarity between measured and actual values. Resolution (often referred to as Resolution) is the minimum value that a device can effectively distinguish. For analog instruments, Resolution is the index value.
For example, if the minimum scale of the ruler is 1 mm, the Resolution is 1 mm. You can also directly view the interval between the last digits displayed by the instrument. For example, the channel can display values of 410.01v, 410.02v, etc., so Resolution is 0.01v because the interval between the last values it can display is 0.01.
To improve the accuracy of the instrument, it is necessary to have enough resolution to ensure it, but it is not that the higher the resolution, the higher the accuracy.
High resolution does not mean higher precision. For example, if you measure a voltage and the actual value is 60.01v, the resolution of your instrument is already very high, 0.00001, but if the measured value is 51.00008v, the measurement value is also inaccurate.
1. The accuracy is close to the truth, i.e. absolute error or relative error. Difficult to reach 0.01%
2 accuracy. Resolution is the fineness of a quantitative scale. To achieve a resolution of 0.00001% (e.g. 24-bit aD, 0.0000056%)
3 is not very difficult. Conceptual understanding:
Example: 1 meter q with 1000 scales, Resolution of 1mm (Resolution 0.1%), absolute error of +5mm, accuracy of +0.5%. If you can lengthen the ruler by 20 mm, the absolute error will be +25 mm and the accuracy will be reduced to 2.5%. However, the scale still has 1000 scales and its resolution is still 1mm (0.1%)
Forgas detector, Resolution, and precision are often mentioned. So Resolution is just the minimum value that can be displayed. The accuracy is the relative error value of the full scale. In general, it is plus or minus five percent of the qualification, and some can achieve higher accuracy. RightsensorsThe higher the requirements, the higher the quality of high precision in general, and the resolution is relatively easy to achieve.
