Denition of typical, minimum and maximum values
Minimum and maximum values for specied 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 specied 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 denition 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 dened 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 a product.

Typical performance characteristics continued
Figure 15 (output RMS noise voltage spectral density) shows
that there are no signicant discrete frequencies in the output.
Figure 16 conrms the absence of steps in the total output
RMS noise current that would indicate discrete frequencies.
To calculate the noise in a frequency band f1to f2, the formula
is:
with Ino(f) read from gure 16 (typical, RMS value).
Example:
What is the noise from 10 to 100 Hz?
Figure 16 gives Ino(10 Hz) = 0.26 µA and
Ino(100 Hz) = 0.8 µA.
The output RMS current noise is therefore.

Performance parameters denition
Sensitivity and linearity
To measure sensitivity and linearity, the primary voltage (DC)
is cycled from 0 to UP M, then to −UP M and back to 0 (equally
spaced UP M/10 steps).
The sensitivity S is dened as the slope of the linear
regression line for a cycle between ±UP M.
The linearity error εLis the maximum positive or negative
di󰀨erence between the measured points and the linear
regression line, expressed in % of the maximum measured
value.
Electrical o󰀨set
The electrical o󰀨set current IO E is the residual output current
when the input voltage is zero.
The temperature variation IO T of the electrical o󰀨set current
IO E is the variation of the electrical o󰀨set from 25 °C to the
considered temperature.
Total error
The overall accuracy εtot is the error at ±UP N, relative to the
rated value UP N.
It includes all errors mentioned above.
Delay times
The delay time tD 10 and the delay time tD 90 are shown in the
next gure.
Both depend on the primary voltage dv/dt. They are measured
at nominal voltage.

Transducer simplied model
The static model of the transducer at temperature TAis:
IS= S⋅UP+ ε
In which
ε= IO E + IOT(TA) + εS⋅S⋅UP + εST(TA)⋅S⋅UP+ εL⋅S⋅UP M
IS : secondary current (A)
S : sensitivity of the transducer (μA/V)
UP : primary voltage (V)
UP M : primary voltage, measuring range (V)
TA : ambient operating temperature (°C)
IO E : electrical o󰀨set current (A)
IOT(TA) : temperature variation of IOat
temperature TA (A)
εS : sensitivity error at 25 °C
εS T (TA) : temperature variation of sensitivity error
at temperature TA
εL: linearity error
This is the absolute maximum error. As all errors are indepen-
dent, a more realistic way to calculate the error would be to

Safety
This transducer must be used in limited-energy secondary
circuits according to IEC 61010-1.
This transducer must be used in electric/electronic equipment
with respect to applicable standards and safety requirements in
accordance with the manufacturer’s operating instructions.
Caution, risk of electrical shock
When operating the transducer, certain parts of the module
can carry hazardous voltage (e.g. primary connections, power
supply). Ignoring this warning can lead to injury and/or cause
serious damage. This transducer is a build-in device, whose
