4. Define the curve for each process fluid.
a. Choose Viscosity at Specific Temp.
b. Choose Fluid 1.
c. Enter two temperature values, one in Temperature 1 and one in Temperature 2.
Enter the temperature in the currently configured temperature unit.
d. For each temperature, enter the viscosity of your process fluid at that
temperature.
Important
You must enter the viscosity in cSt (centistokes). If cP is displayed rather than cSt, send
data to the transmitter to refresh the display.
e. Press the back arrow and repeat this step until curves have been defined for all
fluids.
5. Enter two reference temperatures.
The first reference temperature will be used to calculate the Referred Viscosity
process variable. The second reference temperature will be used to calculate the
Referred Viscosity (Secondary) process variable. They do not need to be within the
temperature range of the curve.
6. Choose the method to be used to supply temperature data, and perform the
required setup.
Method Description Setup
Internal RTD tem-
perature data
Temperature data from the on-
board temperature sensor
(RTD) is used.
a. Choose Configure > Manual Setup > Measurements > Optional Setup
> External Inputs > Temperature.
b. Set External Temperature for Viscosity to Disable.
