FIELD: electricity.
SUBSTANCE: method includes the placement of transmitting and measuring loops, a periodic feeding from the current pulse generator to the input of the loop and periodically, in pauses between pulses, recording the induced EMF in the measuring loop, presenting the pulse width of the generated current, measuring the current pulse value and recording the ratio of the induced EMF value to the measured value of the current, the accumulation in time of the indicated ratios and the calculation of the average value of the ratio by the number of points chosen on the decay curve. The software determines the step size of the time sampling on the decay curve for at least one microsecond, and for each chosen point recorded by the results of 2n measurements of the average value of the ratio of the induced EMF to the measured value of the GC at the time before the switching off of the pulse of this current, where n is selected from 0 to 8. The device contains a light and sound board, batteries, a microprocessor, a PSU, a docking port, a switchboard, amplifiers, an ADC, a current pulse generator, a voltage meter on the battery, a transmitting loop, a measuring loop, a power key, a current measuring unit in the transmitter loop.
EFFECT: increase accuracy and reliability of measurement results.
