Voltmeter `` VK7-6 ''.

Instruments for adjusting and controlling the PTA.The VK7-6 voltmeter has been produced since the 1st quarter of 1961 at the Punane-RET plant. The voltmeter is designed to measure the values ​​of the sinusoidal voltage of LF and HF direct and alternating current, the magnitude of the direct current and the magnitude of the resistance to direct current. A more detailed description of the VK7-6 voltmeter is below.
