Other info

Rotating dipole field mill. The field mill’s frequency bandwidth is from 0 to 10 Hz, sensitivity 2 V/m, amplitude range ± 1500 V/m, and the output
voltage of ±3.5 V. The system requires 12 V buffer power supply. The field mills are mounted on steel support towers with a boom 2.5 m above the surface.
