Common Digital in Geophysical Electrical Method: Supply Current: 1mA ~ 2A. When the supply current of less than 10mA, low SNR. Improving ground conditions improve power supply current is the most effective measures to ensure data quality...[more]
About Infinity pole during electrical resistivity method Three-pole arrangement: AB (5 * AM) allows infinite pole impact 5% Two-pole arrangement: AB (20 * AM) and MN (20 * AM) allows infinite pole impact 5% Do the two-dimensional...[more]
How to select the arrangement Wenner arrangement: highest signal to noise ratio, good vertical resolution, but poor horizontal resolution, multi-channel instrument can be used on only one channel. Symmetrical quadrupole arrangement (Schlumbe...[more]
