sensors

The. mode. ‘Search. of. defects’. is. switched. on. and. off. automatically,. when. connecting. and.

disconnecting.external.sensors.DKI-117,.DOLK-117..The.mode.«Search.for.defects».with.external.
sensors.DKI-117/DODK-117.was.added.for.search.of.insulation.defects.

The.search.of.defects.of.cable.defects.can.be.carried.out.at.all.frequencies.both.in.an.active,.and.

passive.modes.
