AUDIO-FREQUENCY VOLTMETER Model 2017
1. Model
2017
is a rectifier type instrument that has low power
consumption and can be used to measure a wide range of current
frequencies from commercial frequencies to audio frequencies (approx.
10 kHz).
2. The
2017
voltmeter has 4 measuring ranges and designed to indicate
mean values of sine waves (received from the rectifier circuit) in terms
of root-mean-square values (on an rms scale). For this reason, the
voltmeter produces errors due to distortion in waveforms. Care must be
taken since the instrument will produce errors ranging from -6 to 3.8%
in the measurements of waveforms comprising a third harmonic content
of 15%, though this depends on the harmonic's phase angle.
