transducer.

Displaying Data
The typical display screen shown has the
to the left of the y-axis and there is a message line below the graph
that initially indicates the starting date and time of the graphed signal.
Notice that most of the locator bar has been replaced by a status line
in standard video that shows the signal amplitude and the time (in
microseconds) of the measurement at the current cursor location.
However, there is still an inverse video pointer at the far right of this
line to indicate that additional option bar choices are available. See
Table 2-7 below for a complete description of the nine functions
available on the option bar.

In addition to the functions available on the option bar, some of the
numeric keys are used to specify which transducer signal is displayed
and to scale the resulting graph. Table 2-8 on page 2-12 lists these
functions.
