4. The difference between the constant temperature and humidity tester according to the nature:
The measurement uncertainty uncertainty component generally does not need to distinguish its nature. If it needs to be distinguished, it should be expressed as: "Uncertainty component introduced by random effects" and "Uncertainty component introduced by system effects"
The measurement error can be divided into two types: random error and system error according to the nature. By definition, random error and system error are ideal concepts in the case of infinite multiple measurements.
5. The difference between the constant temperature and humidity tester to correct the measurement results:
The term "uncertainty" itself implies an estimable value. It does not refer to a specific and exact error value. Although it can be estimated, it cannot be used to correct the measured value. The uncertainty introduced by the imperfect correction is considered in the uncertainty;
If the estimated value of the systematic error is known, the measurement result can be corrected to obtain the corrected measurement result.
After a value is corrected, it may be closer to the true value, but its uncertainty not only does not decrease, but sometimes it becomes larger. This is mainly because we cannot know exactly what the true value is, and can only estimate the degree to which the measurement result of the constant temperature and humidity tester approaches or departs from the true value.
