FIELD: tool-making industry, in particular, engineering of devices for measuring components and full induction vector of Earth magnetic field.
SUBSTANCE: device contains three transformation channels with serially connected ferro-probe and amplification-transformation block code-controlled by control and recording block, first commutator for switching test currents of ferro-probes from currents stabilizer outputs and second commutator for switching output voltages of transformation channels.
EFFECT: autonomous control, simplification of device.
