Ruler:
When the Ruler is activated, the screen
takes on an appearance as shown in the
screenshot. The function bar contains the
commands which can be accessed for the
ruler.
Using the arrow keys by themselves enables
you to determine the pressure at a particular
point in time. If you move the ruler using the
arrow keys parallel to the x- and y-axis to a
specific measurement point in the curve, the
associated x- and y-values are shown along
the axis, colour-highlighted with the colour of
the measurement curve.
To measure a pressure pulse in time and
amplitude
, for example, use the Differential
function. Proceed as follows:
First shift the x- and y-ruler to the starting
point of the pressure pulse using the arrow
keys. Then press the Shift key in addition to
the arrow keys and keep it pressed. As soon
as you actuate one of the arrow keys, a
second x- and y-ruler appears, which you
can move to the end point of the pressure
pulse using the arrow keys (continue to
depress the Shift key).
Now you can release the Shift key. The
value of the pressure differential is shown
relative to the starting value along the y-axis;
the duration of the pressure pulse (now
colour-highlighted) is shown along the x-axis.
To exit the Ruler, press Esc.
