Description

The ELR-4 and Elrm-4 arrangement, keep up all the fundamental attributes of the 96 mm x 96 mm arrangement, despite the fact that their lessened measurements. The instrument , fitted with channels at the information circuits, is essentially safe to outer unsettling influences, so as the beat flows with dc segments, consenting to the necessities of VDE 0664 and undertaking IEC 23 Standards.

An extraordinary normal for the present transfers, is the lasting control of the Toroidal - ELR circuit. Its interference brings along the prompt trek of the assurance. This permits to distinguish the abnormality, without holding up to the periodical control, made with the Test push catch.
