    Millivoltmeter V3-13 (V3-13, V-3-13; v3-13; v 3-13; v-3-13)    

    Millivoltmeter V3-13 - tube device used to measure the effective value of the sinusoidal alternating voltages.

    Measuring range: from 0.5 mV to 300V.
    Frequency: 20Hz to 1MHz.
    Power: 50W.
    Dimensions of the device. 300 × 220 × 165mm.
    Weight: about 6kg.

    Millivoltmeters V3-13 are in the form of portable devices with a vertical front panel, which has the following elements:
    - Handle the switch limits of measurement;
    - Input jack;
    - Grounding terminal;
    - Switch on the network port - "NETWORK";
    - The mains fuse;
    - Indicator light;
    - The measuring pointer instrument.

    Specifications V3-13

    Instrument error V3-13, expressed as a percentage of the final value of the working end of the scale, does not exceed:
    - ± 4% within 3mV - 1B in the frequency range of 20Hz - 1MHz;
    - 44% to within 3V - 300V in the frequency range of 20Hz-20MHz;
    - ± 6% for the range 3V - 300V, frequency range 20 kHz - 1 MHz.

    Change readings caused by deviation from the ambient temperature 293 ± 5 ° K (+20 ± 5 ° C) to any temperature in the range of 263 to 313 ° K (-10 ° C to -40 ° C) does not exceed ± 3 % for every 10 ° change in temperature. Change readings caused by a deviation from the nominal supply voltage of ± 10% shall not exceed half of the basic error. Changes display B3-13 percent of full scale value, the measured voltage caused klirfaktorom to 20%, does not exceed half the value klirfaktora percentage.

    Input impedance V3-13:
    - 1000g at a frequency fi: 1.0 MW - at the limits 3mV - 1V, 1.6 MW - to within 3V - 300V;
    - At a frequency of 1 mg q: 400Om.

    Input capacity, not more:
    - 25pF n and within 3mV - 1B;
    - 15pF to within 3V - 300V.
    MTBF of the device is 1400 hours. V3-13 is ready for use within 5 minutes after it starts.
