Millivoltmeter analog AC V3-39 (V3 39, V339, Vз-39, b3-39, b3 39, b339)
Measurement of a sinusoidal voltage of of alternating current.
Use as a voltage converter or a broadband amplifier.
Measuring range 100mkv - 300V, frequency range 20Hz - 10MHz.
Error of 2,5-15%. Bx. Pair., cap.: 4MOm, and 1M 30pF, 15pF (with a divider).
152h206h300mm dimensions, weight 5kg.

Millivoltmeter analog AC V3-39 is designed for measuring a sinusoidal AC voltage of 0.1 mV to 300 V in the frequency range from 20 Hz to 10 MHz. The readings are proportional to the mean, and the range is scaled to the effective values ​​of sinusoidal voltage. Millivoltmeter analog AC V3-39 has a separate scale is graduated in decibels. Level "0" dB is 0.775 V. The device can be used as an AC voltage to DC in terms of the effective value of a sine wave.

To the unit Millivoltmeter analog AC V3-39 is attached to a voltage divider DN-108 with the division ratio 1:10, which allows to reduce the capacity supplied to the measuring point.
