Universal lamp voltmeter `` VLU-2 ''.
Instruments for adjusting and controlling the PTA.The universal lamp voltmeter "VLU-2" has been produced since the beginning of 1957. The portable multi-range device "VLU-2" (with dividers DNS-8, DNE-7 and DNE-6) is designed to measure AC and DC voltage in the frequency range from 20 Hz to 400 MHz and is designed for use in laboratories, factory workshops and workshops. Equipped with a probe and capacitive dividers. Main technical characteristics: Limits of measured voltages from 0.1 to 150 V. Limits of measurement 0-1-5-5-15-50-150 V. Active input resistance at a frequency of up to 50 Hz - 10 MΩ, at a frequency above 100 MHz - 50 kΩ. The basic error of the device is 2.5%. The device is powered by an alternating current network of 110, 127 or 220 V (50 Hz). Power consumption 65 watts. The measurement limits of the device can be extended by using dividers attached to the voltmeter: DNS-8 up to 5000 V, DNE-7 up to 5000 V (from 20 Hz to 5 kHz), DNE-6 up to 5000 V (from 5 kHz to 30 MHz) ...
