9.3 Adjust viscosity measurement with Viscosity
Meter Factor
You can adjust viscosity measurement by applying a viscosity meter factor. The measured
dynamic viscosity is always multiplied by the viscosity meter factor. The result is used in
further calculations.

• Calculate and enter Viscosity Meter Factor manually (Section 9.3.4)
9.3.1 Adjust viscosity measurement with Viscosity Meter Factor
using the display
You can adjust viscosity measurement by applying a viscosity meter factor. The measured
dynamic viscosity is always multiplied by the viscosity meter factor. The result is used in
further calculations.
The default value of Viscosity Meter Factor is 1.0. Accordingly, the default value has no effect
on the line viscosity value.
Your meter is calibrated for one to four viscosity ranges. There is a separate meter factor
for each range. You can calculate or enter a meter factor for any or all of the viscosity
ranges.
Tip
You can adjust line viscosity measurement with Viscosity Meter Factor, Viscosity Offset, or both. Viscosity
Meter Factor is applied to the measured dynamic viscosity, and Viscosity Offset is added to the result.
Kinematic viscosity is calculated from this value. Referred viscosity may be calculated from either
dynamic viscosity or kinematic viscosity, depending on the configuration.
Prerequisites
Referred viscosity measurement must be configured before you can use the meter to
calculate the viscosity meter factor. If you are not using referred viscosity, you must enter
the viscosity meter factor manually.
You must be able to obtain a laboratory value for the dynamic viscosity of your process
fluid at Reference Temperature 1. This temperature value was specified during referred
viscosity configuration.
