The NFM‐1 near‐field‐strength meter developed in the German Democratic Republic utilizes two dipole probes designed for 60 kHz to 350 MHz. The measuring ranges of the probes overlap each other from 10 MHz to 30 MHz. The meter operates over the temperature range −10°C to +40°C. Field strength meters of 2 V m−1to 2500 V m−1sensitivity with a measuring error of ⩽ 20% must be calibrated by special equipment designed for the purpose. A calibrating stand based on the principle of a parallelplate capacitor is used in the frequency range from 60 kHz to 18 MHz, and a triplate‐stripline (TEM‐cell) is used in the frequency range from 10 MHz to 350 MHz, for calibrating the probes. Large‐scale measurements were made in 1976 by which the NFM‐1 meter was compared with the corresponding near‐field‐strength meters used in the USSR,
