Basic performance of measuring instruments
1. Accuracy
(1) Precision δ
It indicates the dispersion of instrument indication values, that is, the degree of dispersion of measurement results (indication values) for a stable measured object, measured by the same measurer using the same instrument multiple times in a relatively short period of time. δ The smaller the measurement, the more precise it is.
For example, the precision of a certain temperature instrument δ= 0.5 ℃ means that the dispersion degree of multiple measurement results is not greater than 0.5 ℃. Precision is a sign of the size of random error, and high precision means small random error.
However, it must be noted that precision and accuracy are two separate concepts, and high precision does not necessarily mean accuracy.
(2) Accuracy ε
It indicates the degree of deviation between the instrument indication value and the true value.
For example, the accuracy of a certain flow meter ε= 0.3m3/s indicates that the indicated value of the instrument deviates from the true value by 0.3m3/s. Accuracy is a sign of the size of system error, and high accuracy means small system error. Similarly, high accuracy does not necessarily mean precision.
(3) Accuracy τ
It is a comprehensive reflection of precision and accuracy, with high precision indicating that both precision and accuracy are relatively high. In the simplest case, the algebraic sum of the two can be taken, i.e τ=δ+ε。 Accuracy is often expressed as the relative value of measurement error.
2. Stability
(1) Stability
Refers to the change in the indicated value caused by the instrument's own random changes, periodic changes, drift, etc. within a specified time and under unchanged measurement conditions. Generally, the precision value of the instrument is expressed together with the length of time.
For example, if the voltage indication value of a certain instrument changes by 1.3V per hour, the stability can be expressed as 1.3mV/h.
(2) Impact quantity
The amount of change in the indicator value caused by changes in the external environment of a measuring instrument is called the influence quantity. It is caused by external environmental influences such as temperature, humidity, air pressure, vibration, power supply voltage, and power supply frequency. When explaining the impact, it is necessary to indicate both the influencing factors and the deviation from the indicated value.
For example, if a certain instrument changes its indicated value by 0.02mA due to a 10% change in power supply voltage, it should be written as 0.02mA/U ± 10%.
