Voltmeter lamp universal "VLU-2" was produced from the beginning of 1957. Portable multi-limiting device "VLU-2" (with dividers DNS-8, DNE-7 and DNE-6) is designed to measure DC and AC voltage in the frequency range from 20 Hz to 400 MHz and is designed for use in laboratories, factory workshops and workshops. It is completed with the probe and capacitor dividers. Main technical characteristics: Limits of measured voltages from 0.1 to 150 V. Measurement limits are 0-1-5-5-15-50-150 V. Active input impedance at a frequency of up to 50 Hz is 10 MΩ, at a frequency above 100 MHz - 50 kΩ The main error of the device is 2.5%. Power supply of the device - AC mains 110, 127 or 220 V (50 Hz). 65 watts consumed Measurement limits of the device can be extended when using dividers attached to a voltmeter: DNS-8 to 5000 V, DNE-7 to 5000 V (from 20 Hz to 5 kHz), DNE-6 to 5000 V (from 5 kHz to 30 MHz) .
