Current tongs

Tongs current-measuring (current) are instruments from a series of the professional electrical measuring tools, intended for measuring the current without the break of the current circuit, line voltage of direct current with the voltage also of alternating current with the nominal stress out of 1000[V] with frequency of 50 and 60[Gts], resistance, temperature, frequency, and also checking of diodes and contacts. They have the verification capacity of insulation resistance.
