PURPOSE
If short one time changes are to be recorded, then it is best to use a transient
recorder. This device can best be compared to a tape recorder, but is used for
recording electrical signals. The signal recorder is nothing other than an
oscilloscope with a very slow time base. The advantage of a digital recorder is
that the signals can be s tored on disk, so that they can be used for analysis at
a later time. By making the timescale very slow, and by selecting the automatic
save function, signals can be checked for up to 1 year, and on the two
channels simultaneously. By using the markers it can also be accurately
determined when a change has occurred and how large the change is.
