Recording and Storage

For much work, especially for initial investigations and development, there is little point in recording masses of data, whether T.E. or vibration. Displaying the information directly on an oscilloscope, preferably triggered to synchronise with I/rev of pinion or wheel is very valuable and should never be omitted. It is especially useful when the problem occurs at particular points in the revolution. A typical example is the noise of a timing drive clatter on a diesel engine.
