Setting the Solvent Viscosity (Classic Flow Meter)
To set the viscosity for the solvent that you are using, follow these steps:
1. In Chromeleon, open the Commands dialog box for the NC pump (→ page 89).
2. Select %A_Viscosity (or %B_Viscosity) and then select the preferred solvent from
the list.
Fig. 32: Setting the solvent viscosity (Classic flow meter only)
3. If the viscosity for the solvent that you are using is not yet available in Chromeleon
♦ Follow the steps on page 114 to perform a viscosity measurement for the solvent to
be added to the list in Chromeleon.
♦ Type a viscosity value that has been established earlier as described in this manual
directly in the input box.
Note that values entered here will not be added to the Chromeleon viscosity list. This
value will be used until you establish and save a new value or enter a different value
in Chromeleon.
Note the following for the solvent viscosity setting:
• The viscosity values are relative and refer to water at 42 °C.
• It is not possible to calculate the viscosity of premixed solvents from the viscosities and
mixing ratio of the components. Therefore, establish the viscosity as described in
section 5.5.3.2 on page 114.
• If you are using a solvent with up to 2 % additive, it is sufficient to select the main
solvent from the list.
