Crystalline diode meter `` IKD-1 ''.

Instruments for adjusting and controlling the PTA.The IKD-1 crystal diode meter has been produced since the 1st quarter of 1959 by the Gorky Frunze Plant. The device is designed to assess the suitability and parameters of semiconductor diodes, their selection by parameters. The diode is checked for forward and reverse current and forward and reverse resistance.
