Technical data
Measurement range of the instrument voltmeter V3-49 voltages from 10 mV to 100 V, four overlapping sub-bands with a resolution of 10 -4 of the final value sub-band:
a) from 10.00 to 100.00 mV mV
b) from 0.1000 V to 1.0000 in
c) from 1,000 V to 10,000
g) from 10.00 to 100.00 in In
The normal frequency range of the measured AC voltage of 20 Hz to 10 MHz, work - over 10 MHz to 1000 MHz. The basic error of the instrument in the normal range of frequencies, expressed as a percentage of reading does not exceed:
DOS δ = ± (0,2 + 0,08 / U)% (1)
where U - an instrument reading in volts.
The standard deviation of a random composition of Barking error (S) does not exceed one tenth of the basic error.
Error of the instrument voltmeter V3-49 working in the field of frequency tion is expressed as a percentage of the readings relative to the averaged frequency response shall not exceed:
δ = ± (0,2 + 0,08 / U + 0,008 f)% (2)
where f - frequency voltage measured in MHz. When an individual certification of measuring diodes instrument error in the working frequency range on the individual frequency response does not exceed
δ = ± (0,2 + 0,08 / U + 0,0035 f)% (3)
It shall be accompanied by a certified diodes individual characteristic of the frequency error. Change readings caused ambient air temperature deviation from normal to any temperature within the operating temperature range from 278 K (5 ° C) to 313 K (40 ° C) does not exceed one half of the basic error for every 10 K temperature change.
Change the voltmeter V3-49 readings caused by voltage tolerance at 50 ± 0,5 Hz, the nominal value of ± 22 V and the deviation of the supply voltage frequency of 400 +28 / -12 Hz from the nominal value by ± 11 V, does not exceed half of the basic error. In this case, the correction may be zero, and the filament voltage controls.

Voltmeter V3-49 provide their specifications within the standards set specifications, after samoprogreva time of 30 minutes.
The device retains its specifications within the standards set specifications, when powered from the mains AC voltage of 220 ± 22 V, 50 Hz ± 0,5 and harmonic content up to 5% and the mains voltage of 220 ± 11V at 400 +28 / - 12 Hz and harmonic content to 5%.
The power consumed by the device from the network at the rated voltage does not exceed 65 VA. The device provides the ability to remotely control the compensation voltage and measuring sub-bands, as well as remote control of zero-balance indicator.
Note. Zeroing filament voltage diode remotely is not available.
Voltmeter V3-49 has tsifropechatayuschee output to an external unit (CPU) in the code 8-4-2-1. The device issues a command to start to start the CPU after the measurement (obtaining a zero-balance indicator). The device allows for continuous operation in the operating conditions for 8 hours while maintaining its specifications within the standards set specifications. At the same time ensures the normal patterns of EEC, the RFP details and elements within the norms, standards and specifications for them.
Note. Continuous operation time does not include time samoprogreva.
Voltmeter V3-49 retain their specifications within the standards set by TU, after the change in the measurement of n diode 6D24N of SPTA.

In the technical documentation for each device or product, information is provided on the list and amount of precious metals content. The documentation gives the exact weight in grams of precious metals: Au gold, palladium Pd, platinum Pt, silver Ag, tantalum Ta and other platinum group metals (PGM) per unit item. These precious metals are found in nature in very limited quantities and therefore have such a high price.

On our website you can familiarize yourself with the technical characteristics of devices and obtain information on the content of precious metals in devices and radio components manufactured in the USSR. We draw your attention to the fact that often the actual content of precious metals differs by 10-25% from the reference one in a smaller direction!
