Pulse voltmeter "В4-2" was produced presumably since 1965. The voltmeter is designed to measure the voltage of video pulses of positive and negative polarity. The measurement range is from 3 to 150 V. The basic measurement error is ± 4%. Three measurement limits of 15 V; 50 V; 150 V. Measurement range with a divider from 3 to 500 V. Power supply from a network of 220 V. Power consumption 30 V · A. Overall dimensions 310х220х210 mm. Weight 7 kg.
