1.7.4 Temperature Input
The Model XGS868 can use either a fixed temperature value or a live temperature input to calculate the steam density
for the mass flow rate display.
3. Scroll to a Fixed temperature value or to set up the option card in Slot 1 that will supply the live temperature input
and press [Enter].
Note: If Slot 1 contains an activated option card with an analog input assigned to
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. If there is no active option card for temperature, the meter
assumes you are using a fixed temperature.
•
If you selected Fixed, proceed to Step 4.
•
If you selected Slot 1, proceed to Step 5.
4. Enter the known Fixed Temp. (process temperature) and press [Enter]. The meter will accept values from -328 to
1,832°F (-200 to 1,000
5. Scroll to Input A or Input B and press [Enter]. The inputs were labeled during setup.
Note: The set up of Input A is used as an example. Identical procedures would be used to set up Input B.
1.7.5 Base Temperature
6. Use the arrow keys to enter the Base Temperature and press [Enter]. The ratio of this value to the actual
temperature is used to calculate the standard mass flow rate.

If you selected
If you selected Pressure as the Steam Input Type, proceed to Step 7 below.

1.7.6 Pressure Input
7. Scroll to a Fixed pressure value or to set up the option card in Slot 1 that will supply the live pressure input and
press [Enter].
Note: If Slot 1 contains an activated option card with an input assigned to
above prompt. If the process pressure is stable, a fixed value may be used, but most applications require a live
pressure input. If there is no active option card for pressure, the meter assumes you are using a fixed pressure.
If you selected Fixed, proceed to Step 8.
•
If you selected Slot 1, proceed to Step 9.
•
8. Enter the known Fixed process Pressure and press [Enter]. The meter will only accept values from 0 to 5,000 psia.
Proceed to Base Pressure in Step 10.
9. Scroll to Input A or Input B and press [Enter]. The inputs were labeled during setup.
Note: The set up of Input A is used as an example. Identical procedures would be used to set up Input B.
