Definition of typical, minimum and maximum values
Minimum and maximum values for specified limiting and safety conditions have to be understood as such as well as values shown
in “typical” graphs.
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.

To calculate the total output RMS noise in a frequency band f1
to f2, the formula is:
Uno(f1 to f2) = Uno (f2)2 − Uno (f1)2
with Uno(f) read from figure 13 (typical, RMS value).
Example:
What is the total output RMS noise from 100 to 1 kHz?
Figure 13 gives Uno(100 Hz) = 8 mV and Uno(1 kHz) = 25 mV.
Therefore, the total output RMS noise voltage referred to
primary is 24 mV.

This model is valid for primary voltage UP between 0 and +UP

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:
ε=

∑
ε i2
The total error εtot is the error at ±UP N, relative to the rated value
UP N.
It includes all errors mentioned above
● the electrical offset UO E
● the sensitivity error εS

Figure 15: v oltage cycle used to measure the electrical offset
(transducer supplied)
Using the voltage cycle shown in previous figure, the electrical
offset voltage UO E is the residual output referred to primary
when the input voltage is zero.
The temperature variation UO T of the electrical offset voltage
UO E =
U P (3) + U P (5)

U O T (T ) = U O E (T ) − U O E ( 25 °C )
To measure sensitivity and linearity, the primary voltage (DC) is
cycled from 0 to UP, then to −UP and back to 0 (equally spaced
UP/10 steps). The sensitivity S is defined as the slope of the
linear regression line for a cycle between ±UP N.
The linearity error εL is the maximum positive or negative
difference between the measured points and the linear
regression line, expressed in % of UP N.
Delay times

The delay time tD 10 @ 10 % and the delay time tD 90 @ 90 % with

Both slightly depend on the primary voltage dv/dt.
