The Model 502 is a dual function hand held instrument specifically designed for train repair applications.
The Model 502 is a dual function (counts and generates AC waveforms) hand held instrument 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, the Model 502 provides precise counting of input and output frequencies that can be converted to your specific engineering units.
Typical Applications: For the Calibration or Functional Check of Equipment utilizing frequency based waveforms representing parameters such as RPM, GPM, FPM or MPH.
