Measuring instrument of the output of radio receivers `` V3-10A ''.
Instruments for adjusting and controlling the PTA.The V3-10A radio output meter (IVP-3M) has been produced since 1962 by the Kalibr Minsk plant. The device is designed to measure signal voltages and noise at the output of radio receivers and LF amplifiers. The range of measured voltages is from 30 mV to 300 Volts. Frequency range from 50 to 10000 Hz. Basic error +/- 4% of the upper scale limit. Input impedance 20 kOhm. The device is powered by a KBS-X-0.7 (3R-12) battery, while the consumption does not exceed 5 mW. The dimensions of the device are 160x120x115 mm. Its weight is 2 kg. In 1969, the circuit of the device was improved.
