What does the statistical error in instrument measurement mean?
For a pressure transmitter of accuracy 0.1,Output maximum allowable error = output range * instrument accuracy% = 16 * 0.001 = 0.016 (mA)That is, the maximum possible error in this meter is positive and negative 0.016mAThe true value of the measurement is called the error of measurement. It is also called absolute error. In the verification process, the error value shall not exceed the maximum allowable error, otherwise the instrument will be judged to be unqualified (ultra precision).In actual measurement, the error will not exceed the maximum allowable error.
Maximum allowable error / range of measurement *% = instrument accuracyRemove the instrument precision instrument precision is the percent.
The accuracy of a measuring instrument is an indicator of the reliability of the instrument's measured value.The instrument has a maximum allowable error (deviation), which means that the probability of measuring N times in the same measured value (no more than 98%) is not exceeded.
