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, minimum and maximum values are determined during the initial characterization of the product.

Figure 11 confirms the absence of steps in the total output current noise that would indicate discrete frequencies. To calculate the noise in a frequency band f1 to f2, the formula is: Ino(f1 to f2) = Ino(f2) − Ino(f1) 2 2 with Ino(f) read from figure 11 (typical, rms value). Example: What is the noise from 10 to 100 Hz? Figure 11 gives Ino(10 Hz) = 0.26 µA and Ino(100 Hz) = 0.8 µA. The output rms current noise is therefore.

As all errors are independent, a more realistic way to calculate the error would be to use the following formula: ε= N ∑ε 𝑖𝑖 =1 2 𝑖𝑖 Sensitivity and linearity To measure sensitivity and linearity, the primary voltage (DC) is cycled from 0 to VPM, then to −VPM and back to 0 (equally spaced VPM/10 steps). The sensitivity G is defined as the slope of the linear regression line for a cycle between ±VPM. The linearity error εL is the maximum positive or negative difference between the measured points and the linear regression line, expressed in % of the maximum measured value. Electrical offset The electrical offset current IOE is the residual output current when the input voltage is zero. The temperature variation IOT of the electrical offset current IOE is the variation of the electrical offset from 25 °C to the considered temperature. Overall accuracy The overall accuracy XG is the error at ±VPN, relative to the rated value VPN. It includes all errors mentionned above. Response and reaction times The response time tr and the reaction time tra are shown in the next figure. Both depend on the primary voltage dv/dt. They are measured at nominal voltage.

Remarks ●● The transducer is directly connected to the primary voltage. ●● The primary cables have to be routed together all the way. ●● The secondary cables also have to be routed together all the way. ●● Installation of the transducer is to be done without primary or secondary voltage present. ●● 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. Caution, risk of electrical shock When operating the transducer, certain parts of the module can carry hazardous voltage (eg. primary connection, power supply). Ignoring this warning can lead to injury and/or cause serious damage. This transducer is a build-in device, whose conducting parts must be inaccessible after installation. A protective housing or additional shield could be used. Main supply must be able to be disconnected. ●● This is a standard model.
