Notes: 1) The standard configuration is with all jumpers in // (1 primary turn) which is the only one calibrated and guaranteed by LEM.
The sensitivity may change slightly for all other configurations, therefore, LEM advises the user to characterize any specific
configuration.
2) The maximum magnetic offset referred to primary is inversely proportional to the number of turns, thus is divided by 2 with 2 turns
and by 4 with 4 turns.
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 a product.
Remark
Installation of the transducer must be done unless otherwise specified on the datasheet, according to LEM Transducer Generic
Mounting Rules. Please refer to LEM document N°ANE120504 available on our Web site: Products/Product Documentation.
