DigitalFlow™ XMT868i Startup Guide 53
Chapter 3. Operation
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 XMT868i 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 XMT868i as described earlier in
this chapter. Then, read the flow rate directly from the display, as shown in Figure 16 on page 49.
Note: See Chapter 2, Displaying Data, in the Programming Manual to customize the contents of the LCD display.
Qup Displays the signal quality for the upstream transducer.
Qdown Displays the signal quality for the downstream transducer.
AMPup Displays the value for the signal amplitude of the upstream transducer.
AMPdn Displays the value for the signal amplitude of the downstream transducer.
P#up Displays signal peaks for the upstream transducer.
P#dn Displays signal peaks for the downstream transducer.
NFup Displays the normalization factor for the upstream transducer.
NFdn Displays the normalization factor for the downstream transducer.
Cxdcr Displays the speed of sound in the transducer (clamp-on only).
TEMPs Displays the temperature for the supply input (energy measurement).
TEMPr Displays the temperature for the return input (energy measurement).
Ts-Tr Difference between supply input and return input measurement (energy measurement).
DENSs Displays the density for the supply input (energy measurement).
DENSr Displays the density for the return input (energy measurement).
DELTh Displays the delta enthalpy which is the difference between the supply and return. Enthalpy is
a measure of energy contained in the fluid (energy measurement).
