Measurement of current and voltages at infrasonic frequencies
Electrical measuring instruments operating as vibrators can be used for measurements at infrasonic frequencies. The maximum frequency of the measured value is determined from the amplitude-frequency characteristic of the instrument on the basis of a given amplitude error.
It is advisable to use a moving-coil instrument with as large a damping as possible for operation as a vibrator.
A unidirectional scale has virtually no effect on the accuracy of measurements at frequencies specified in paragraph 1.
