Potential gradient is measured using a by rotating-dipole field mill .
Frequency bandwidth: 0-10 Hz.
Sensitivity: 2 V/m.
Range: +-1500 V/m.
Output voltage: 3.5 V .
Requires 12 V buffer power supply.
Mounted on steel support towers with a boom 2

The instrument is located at 96 m a.s.l.
Measurement frequency is 1Hz

This is used in the Glocaem potential gradient network
