On the other hand, measured values are part of a statistical distribution that can be specified by an interval with upper and lower limits and a probability for measured values to lie within this interval. Unless otherwise stated (e.g. “100 % tested”), the LEM definition for such intervals designated with “min” and “max” is that the probability for values of samples to lie in this interval is 99.73 %. For a normal (Gaussian) distribution, this corresponds to an interval between −3 sigma and +3 sigma. If “typical” values are not obviously mean or average values, those values are defined to delimit intervals with a probability of 68.27 %, corresponding to an interval between −sigma and +sigma for a normal distribution. Typical, maximal and minimal values are determined during the initial characterization of the product.

This model is valid for primary voltage _U_ P between 0 and + _U_ P only. This is the absolute maximum error. As all errors are independent, a more realistic way to calculate the error would be to use the following formula: The temperature variation _U_ O _T_ of the electrical offset voltage **==> picture [93 x 26] intentionally omitted <==** **==> picture [54 x 37] intentionally omitted <==** _U_ O E is the variation of the electrical offset from 25 °C to the considered temperature. **==> picture [198 x 26] intentionally omitted <==** ## **Total error referred to primary** The total error _ε_ tot is the error at ± _U_ P N, relative to the rated value To measure sensitivity and linearity, the primary voltage (DC) is cycled from 0 to _U_ P, then to − _U_ P and back to 0 (equally spaced _U_ P/10 steps). The sensitivity _S_ is defined as the slope of the linear regression line for a cycle between ± _U_ P N. The linearity error difference between the measured points and the linear _ε_ L is the maximum positive or negative regression line, expressed in % of _U_ P N.. - _U_ P N. It includes all errors mentioned above ●the electrical offset _U_ O E - ●the sensitivity error _ε_ - _S_ - ●the linearity error _ε_ L (to _U_ P N). **==> picture [450 x 189] intentionally omitted <==** **----- Start of picture text -----**
