Davis 502A Dual Function Frequency Counter and Generator

Davis 502A Dual Function Frequency Counter and Generator

Applications

Calibration or functional check of equipment utilizing frequency based waveforms representing parameters such as RPM, GPM, FPM or MPH.

 fs2

This dual function (counts and generates AC waveforms) hand held instrument is specifically designed for train repair applications. This instrument can be used in the calibration of devices such as control panel speedometers and wheel speed transducers. Battery operated, it provides precise counting of input and output frequencies that can be converted to your specific engineering units. Typical applications are calibration or functional check of equipment utilizing frequency based waveforms representing parameters such as RPM, GPM, FPM or MPH.
