Technical characteristics

Millivoltmeter V3-41 (V341, V-3-41, V 3 41, V-341, V 341)
 
Millivoltmeter V3-41 is designed to measure sine wave AC voltage from 0.3 mV to 300V at frequencies from 20Hz to 10MHz.
Readings are proportional to the mean, and scale to calibrate the effective values ​​of the sine wave.
The device has a separate scale scaled in decibels. Level "0" dB equals 0.775 V.
It can be used as a converter of alternating voltage to a constant level of the effective value of sinusoidal voltage.
By the device is attached to divider DV-109 with division ratio of 1:10, which allows to reduce capacity, supplied to the measuring point.
