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
.
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).
