Syscal Kid Switch 24 Automated 24 Electrode Switching System
  BACK

Aegis Instruments is pleased to announce the new multinode resistivity imaging option of its subcompact resistivity meter, the Syscal Kid. Specially designed for shallow resistivity imaging the Switch 24 features an internal switching board supporting 24 electrodes. Two cable strings with 12 electrode take outs each are connected to the back of the meter. Software is provided to automatically perform roll along surveys.

The all new user interface is quickly absorbed so that a wide range of users from archaeologists, to civil engineers, to geologists, can easily take advantage of the Switch 24's capabilities. Select the type of array, enter your electrode spacing, and tell the instrument to start. When sampling is complete move the cables down the line and start again. During data upload chose the profiles to be merged, create a final data file, and send it to Surfer for pseudo section display, or to your imaging software for modeling. Surveys are quickly completed, even with a single operator.

The electrode string is made of heavy duty cable, as typically is used in the seismic industry. Each cable has 12 take outs, spaced at 1, 2, or 3m intervals. A cable with 3m spacing is 40m long and weighs about 2.5Kg. Thus, with two 3m cables a profile would be 72m, or roughly 236 feet. Depending on the type of array used this would yield survey depths in the 200 foot range, or 70m.

General Specifications

The Syscal Kid features what is called autoranging. This means that the instrument automatically sets the correct output voltage based on the level of the measured signal. No more fussing with output voltage selections to get the best measured signal. The Kid also features automatic SP compensation, but does it better than most. What is unique to all of the Syscal meters though, is that during stacking, with every third stack, SP is again measured and reapplied, so that any drift during the stacking process is corrected. The result is a very accurate measurement, even in the presence of significant noise.
