2-4 Displaying Data
The GRAPH Submenu The GRAPH submenu permits the display of either the flow velocity,
mass flow or the volumetric flow on an XY bar graph, with a
specified time interval on the x-axis. This section describes the
procedures for setting up and using the graph format.
Setting Up the GRAPH
Format
Press the appropriate side of the [SCREEN] key to activate the desired
pane of the display screen, and complete the following steps:
1. To access the Display Menu, press the
[DISP] key.
2. Press
[F3] = GRAPH.
3. Press
[F1]-[F3] to graph the Flow Velocity, Volumetric Flow or
Mass Flow, respectively.
4. Use the [←], [→] and
[F1]-[F4] keys to select the desired Time
Increment.
5. Enter a maximum value for the Y-axis (vertical) scale that is larger
than the maximum expected reading and press
[ENT].
6. At the Y Range prompt, press
[F1] to graph only positive Y values
or press
[F2] to graph both positive and negative Y values.
After the
Y RANGE is entered, the Model DF868 automatically begins
taking measurements and displays them in the specified graphical
format. Proceed to the next section for a discussion of manipulating
the graphical display.
