FIELD: the invention refers to measuring technique and may be used for detecting changes of natural (background) electrostatic field in the Earth's biosphere.
SUBSTANCE: the arrangement has a sensitive element fulfilled in the shape of an antenna, an amplifier, a modulator, an intermediate amplifier, a demodulator, a generator, from the first to the fifth integrators, a needle indicator, a commutator, an additional indicator. At that the commutator has a button for starting the arrangement.
EFFECT: increases accuracy and provides possibility to determine the Earth's static electrical fields.
