High power, wide range, high precision: max power up to 9000W (1500V*6A), voltage input range is 160Vp-p, high measuring precision of small signal (voltage is less than 0.1mV and current is less than 0.1mA with ±1% measuring precision);all of which make WDA-1 mainframe an ideal device for regions of high resistivity and to achieve better measured results.

Bluetooth technology,  wireless remote control: Bluetooth technology enables the tablet PC to control the WDA-1 mainframe in 10 meters. It enables all operations as set parameters, start measurement, display result and save data more easily.

Tablet PC operate, powerful function: all operations as parameters setting, data display, data storage, curve drawing all be finished on the tablet PC, easy and visuable for filed data procession.



3D imaging mode is developed from 2D imaging mode. What is the difference between them is, 2D imaging mode divides one big cross-section into different smaller ones and measures all the survey points of small sections to complete the measurement approximately, while 3D imaging mode is developed from 2D, finishing the measurement approximately through combining all the points along the planes of different directions (in column mode) on the basis of 2D measurement. However, 3D imaging mode is not only a simple combination of 2D mode but involves data processing by inversion software to make the inversion model more practical.
