The Model GF868 can use either fixed temperature and pressure
quality values or live measurement inputs to calculate standard
volumetric or mass flow. Complete the following steps to configure
these inputs:
1. At the main I/O menu prompt, press
2. At the Temperature Input prompt, press
temperature value or press
that will supply the live temperature input.
Note: Each slot that contains an option card with an analog input
assigned to TEMP or an RTD input will appear on the option
bar. If the process temperature is stable, a fixed value may be
used, but most applications require a live temperature input.
3. Do one of the following:
•
If you selected FIXED, enter the known fixed process
temperature. Press
from –148° to 662°F.)

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.
b. Enter the Base Temperature (from –148° to 662°F), and press
[ENT] . The ratio of this value to the actual temperature is used
to calculate the standard volumetric flow.
4. At the Pressure Input prompt, press
pressure value or press [Fx] to select the option card in Slot X that
will supply the live pressure input.
Note: Each slot that contains an option card with an analog input
assigned to PRESR will appear on the option bar. If the
process pressure is stable, a fixed value may be used, but most
applications require a live pressure input.
5. Do one of the following:
•
If you selected FIXED, enter the known fixed process pressure.
