DigitalFlow™ XGM868i Startup Guide 49
Chapter 3. Operation
3.5.1 Programming the LCD (cont.)
Note: The measurement units that appear in these prompts are those selected in the GLOBL-SYSTM menu earlier in this
section. Also, when differences in one channel's programming invalidate an output previously chosen for the
other, the measurement defaults to the nearest selectable item in the parameter list.
The previous two prompts repeat until all of the specified # of LCD Parameters have been set up. When all of the
display parameters have been set up, the meter returns to the Global I/O window. To leave the Keypad Program, press
the
[Escape] key three times.
After leaving the Keypad Program, the XGM868i will reset itself and will begin to display the parameters specified in
this section. If more than one parameter was set up, each of the parameters will be displayed in sequence, with a pause
of several seconds between display changes.
3.5.2 Using the LCD Display
To use the programmed LCD display for obtaining flow rate data, simply power on the XGM868i as described earlier
in this chapter. Then, read the flow rate directly from the display, as shown in Figure 16 on page 45.
Note: See Chapter 2, Displaying Data, in the Programming Manual to customize the contents of the LCD display.
