Activating the compensation for a liquid with a linear viscosity
compensation curve
To activate the compensation for a liquid with a viscosity that changes in a linear way with the liquid tem-
perature, do the following:
→
Select the device in the navigation area.

Settings
The current settings are displayed.
→
Select
Linear
→
Set the value of the constant a of the linear curve, in the displayed units (mm
2
/s), and in the scientific
notation. For example, to set the value 0,03724, enter 3.724000E-02 or, to set the value 372,4, enter
3.02.
→
Set the value of the constant b of the linear curve, in the displayed units, and in the scientific notation.
The new settings are displayed.
→
Finish
The compensation for a liquid with a linear compensation curve is active.
If the calculated result of the equation is negative or equal to 0 (for example if the fluid temperature is not
in the range covered by the equation, or if a wrong constant value has been entered), the compensated
volume flow is incorrect and the error message
Viscosity compensation failed
is displayed. If the message
is displayed, do the following:
→
Make sure the fluid temperature is in the range covered by the equation.
→
Make sure you have entered correct a constant value.
