Main features:
  •   Commutates receiving and transmitting lines
  •  64 or 48 electrodes
  •  Any sequence of switching
  • Any array type and combination
  • 25 measurements per minute

Multi-purpose switchbox CommDD2 for electrical survey allows to commutate the receiving and transmitting lines without any limitations. There are 2 possible ways to switch electrodes on the lines – manually or automatically (with a predefined protocol of measurements). The switchbox allows the use of any signal accumulation protocol available for linear or areal measurements in electrical resistivity tomography:

  • on land;
  • on water areas and "water-land" transition zones;
  • and in boreholes

Any sequence of switching is registered in a control file (text format) that is loaded to the switchbox via USB interface. The device has LCD backlit display and keyboard, allowing to select the appropriate protocol from the memory, and also to operate in semiautomatic mode.

The switchbox is compatible with any single - channel receivers and transmitters for electrical survey. The highest performance of CommDD2 is achieved when it is used with receivers that allow automatic switching of receiving electrode pairs through the RS-232 interface (such as MERI-24 receiver). It is also possible to work with other types of receivers due to the open-protocol management of the switchbox.
