1 Introduction ELT-400
1-2
EMC test laboratory
The ELT-400 is ideal for investigating the magnetic fields produced by
household equipment or other electrical devices. The reference test method
described in the latest product standards such as EN 50366 and
prEN 50392 is implemented precisely in this instrument.
Instrument description
The ELT-400 is extremely easy to operate using just 6 buttons and can be
used practically anywhere.
Exposure STD mode
Exposure STD mode is suitable for particularly simple and reliable
measurements on all signal shapes (single or multiple frequency fields,
pulsed fields).
The level of the magnetic field is displayed directly as a percentage of the
reference limit value, regardless of the signal shape and frequency. The
evaluation schemes specified by the relevant safety standards are
implemented in the instrument.
The numerical result therefore clearly expresses the actual situation and
indicates the available safety margin.
Field strength mode
The ELT-400 has a flat frequency response over a very wide frequency
range. Detectors for RMS and peak value measurements can be used for
broadband measurements. The results of field strength measurements are
displayed in µT or mT.
Active probe
The ELT-400 can be connected to an oscilloscope or FFT analyzer for more
in-depth analysis. The signal voltages from all three field probes (isotropic
coil configuration) are output with proper phase. The amplified voltage can
be input directly to the oscilloscope or FFT analyzer.
