What is the measuring range, upper and lower limits and measuring range of the instrument?


The measurement range is the range of the measured variable that the instrument measures with the specified accuracy. The minimum and maximum values of the measurement range are called the lower measurement limit and the upper measurement limit, respectively. The measuring range of the instrument is used to indicate the size of its measuring range, which is the algebraic difference between the upper limit value and the lower limit value, I .e. measuring range = measuring upper limit value-measuring lower limit value. If the measuring range of the instrument is given, the upper and lower limits and measuring range will be known. On the contrary, only the measuring range of the instrument is given, but the upper and lower limits and measuring range cannot be determined.
