FIELD: measurement technology. SUBSTANCE: meter has series-connected main antenna, adjustable amplifier, detector, indicator, and calibrating antenna connected to output of adjustable calibrating generator; calibrating antenna is mounted as close as possible and symmetrically to main antenna; for example, winding circuits of calibrating antenna can be placed above or between winding turns of main antenna uniformly and symmetrically to its turns. EFFECT: improved accuracy and facilitated measurement procedure; simplified design. 2 dwg
