System composition
One DZD-6A multi-functional DC resistivity instrument as the survey
& control unit in the system, equipped with DUK-2A type 60 channels
or 120 channels multiplex electrode converter, cables, electrodes
and other related accessories, together to form the resistivity
imaging system.
Main features
Multiple function in one machine: the instrument has four functions
including long lead IP instrument, 2D high density resistivity
meter 2D high density IP instrument and medium-power short lead
transmitter.
Easy for operation: the instrument adopts all-digital automatic
measurement, thus can execute automatic compensation for
spontaneous potential, drift and electrode polarization.
By adopting large screen LCD display in English characters, more
than fourteen types of wiring working modes can be directly
displayed in high-density measurement mode; in DZD-6A stand-along
mode, nine types of electrode arranging methods can be directly
displayed; meanwhile, real-time curve display can be realized
during working.
