1.3.4.2 Temperature Input (cont.)
4. One of the following two prompts will appear, depending on your selection in Step 3.
• If Fixed was chosen, enter the known fixed process temperature and press [Enter] . The meter will only accept
values from –328° to 1832°F (–200
o
to 1000
o
C).
• If Slot 1 was chosen, scroll to the desired temperature input (from A to D) and press [Enter].
5. At the Temp Return prompt, scroll to Fixed to enter a constant temperature value or on Slot1 to select the output
in Slot 1 that will provide the live temperature input for the return.
Note: If Slot 1 contains an activated option card with an analog input assigned to TEMP or an RTD input, Slot 1
appears as an option at the above prompt. If the process temperature is stable, a fixed value may be used,
but most applications require a live temperature input.

The program now returns to the Channel PROGRAM menu.
1.3.5 Entering Setup Parameters
The signal limits and response times for the Model XMT868i are specified using the SET UP submenu. While following
the programming instructions, refer to Figure 30 on page 9. This submenu includes four options:
•
SIGNL - set the parameters related to the transducer signal
• AVRG - specify the response of the meter to step changes
• INIT - initialize all parameters to default values
• ADVAN - enable mass flow, edit kinematic viscosity vs. sound speed table, activate K factors, and select transmit
code length.
To enter the SET UP submenu, scroll to the SET UP option in the Channel PROGRAM menu and press [Enter].
Remember to record all programmed data in Appendix B, Data Records .
