Regarding the accuracy of the instrument
Thread Content
What is the definition of instrument accuracy? Are there issues with full-scale accuracy and relative accuracy? If I ask the manufacturer about the accuracy of the instrument, which type is he referring to?
Is there anyone who can answer?? ? :'( :'( :'(
What he told you is probably the accuracy within the normal measurement range of the instrument.
I asked two manufacturers, and one said the accuracy is within the normal measurement range； There’s also one that refers to the accuracy of the measurement values. . . I don’t know which one to listen to
The accuracy of an instrument is measured by its error; a larger error indicates lower accuracy, while a smaller error indicates higher accuracy. The accuracy of instruments is an objective reality, which is reflected in the errors. There are different methods for classifying errors. Based on their nature, they can be divided into systematic errors and random errors ； Based on the temporal characteristics of the parameters being measured, errors can be divided into static parameter errors and dynamic parameter errors. Therefore, the precision also needs to be distinguished accordingly.
It generally refers to the accuracy at full scale, expressed as a percentage of the full scale, both positive and negative
