(2) For channel connected to Velocimeter input, set to Frequency = 100.0 +/- 0.01 Hz,
Waveform = Sine wave, Amplitude = 19.0 mV pk.
NOTE: Phase shift between magnetic pickup signal and Velocimeter signal must be zero
degrees on the H-P signal generator. For a description of Chadwick-Helmuth phase
measurement convention, refer to Appendix C.
