Table "Structure and operation of voltmeters"
Name (abbreviation): | Purpose: | Operating principle: | Usage: |
---|---|---|---|
With direct current (B2): | measure voltage in networks with direct current | has polarity, therefore it requires strict observance when connecting: "+" - to the upper point of the potential, "-" - to the lower point | at home |
With alternating current (B3): | measure sinusoidal voltage with a frequency close to 50 Hertz | has no polarity, therefore it is connected in parallel to the load for which the voltage is measured | - |
Pulse (B4): | measure the amplitudes of periodic signals with a large duty cycle and single pulses | - | for verification and certification of radio measuring equipment |
Phase sensitive (B5): | measure the quadrature components of the complex voltages of the first harmonic | makes it possible to determine the complex voltage, taking as zero the initial phase of some reference voltage | to study the amplitude-phase characteristics of quadripoles (amplifiers for example) |
Selective (B6): | to highlight certain harmonic components of complex signals and the RMS value of their voltage | selects certain harmonic signal elements or a narrow frequency band using a tunable filter; measures the current value of selected signals | as a measuring receiver |
Universal (B7): | measurement of direct and alternating currents | - | at home |
