Meter accuracy performance indicators are often used in the project (also known as precision), variation, sensitivity to describe.

Instrument (Figure 3)

Instrument (Figure 3) instrument calibration instruments often tuned precision, variation and sensitivity of the three. Variable poor is refers to instrument was measuring variable (can understanding for entered signal) times from different direction reached same numerical Shi, instrument indicates value Zhijian of maximum poor value, or said is instrument in outside conditions not variable of situation Xia, was measuring parameter by small to big changes (are to characteristics) and was measuring parameter by big to small changes (reverse characteristics) inconsistent of degree, both of poor that for instrument variable poor.
