Section V. Paragraph 5-13. The 410C Voltmeter called for in
the Crest Factor Test has been discontinued. If a 410C
Voltmeter is not available an oscilloscope may be used
to set up the puise trains. The pulses should have an
amplitude of 10.1 Volts for a Crest Factor of 10, and an
amplitude of 10.0 Volts for a Crest Factor of 20. These
amplitudes require that the puise widths and spacings
given in steps c and e remain unchanged.
