Displaying Data 2-13
March 2008
Displaying the
Transducer Signal (cont.)
The typical display screen shown has the
Sup
transducer signal listed
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Notice that most of the locator bar has been replaced by a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.
107 686.798mi Use the [
←]
, [
→]

[F1]-[F4]
keys to select the desired option.
Options are listed in Table 2-6

=
T INC
Display the time increment value in the
message line. This is based on the fre-
