  • Notes

  • For the measurement of harmonic distortion the fundamental frequency is eliminated by an RC system, which is tunable between 25 Hz and 25 kHz. The residue, the frequency range of which extends up to 100 kHz is amplified and measured: the display consists of a pointer type instument calibrated in per cent, decibels and millivolts.
    The instrument can also measure background noise level and can be used as a highly-sensitive millivoltmeter covering a wide frequency range.

    All other characteristics are in the original attached article.
