Chapter 2. Displaying Data
2.1 Introduction
This chapter explains how to display measurement data in various formats. Each of the two display screen panes
may be programmed independently.
Note: The instructions in this chapter assume that the left display pane is active. If the right display pane is active,
simply change all [F1]-[F4] designations to [F5]-[F8].
The following submenus are included in the Display Menu:
• BIG - displays a single measurement in large size text
• DUAL - permits the simultaneous display of two measurements, in the same screen pane, in standard size text
• GRAPH - displays a graph of either velocity or volumetric flow versus time
• LOG - displays the data stored in a log file either graphically or numerically
• SIGNL - graphically displays any one of five transducer signals versus time
• BACKL - sets the time that the LCD display backlight remains on before it is automatically turned off.
Refer to Figure 15 on page 102, and proceed to the appropriate section to set up the Model DF868 display screen(s),
using one of the listed submenus.

Upon power up, a standard measurement mode display (similar to the one shown below) appears. Press the
appropriate side of the [SCREEN] key to activate the desired pane of the display screen, and complete the following
steps:
