ABSTRACT:
Apparatus and method utilized in carrying out vibrational analysis wherein the output of a vibration monitoring transducer is treated by filtering in stepped fashion over a broad spectrum of frequencies. The stepped filtering is provided utilizing minimum dwell intervals at lower frequencies as determined by the number of steps involved per given bandwidth. A readout form of continuous printing provides a histographic analysis of amplitude and frequency and, optionally, an amplitude readout with respect to elapsed time. For the histographic readout, amplitude is plotted as a series of characters in linear form commencing with half peak amplitude and extending toward peak. Test and calibration procedures are provided for facilitating on site testing as well as servicing calibration procedures.
