To edit the Estimated Vs m/s:
To activate numeric entry press
Use PC numeric keys or the Magnetic Wand to enter the sonic velocity value as meters-per-
second.
To register the data press
How to Edit the Viscosity (cS) Setting
The [Viscosity cS] menu cell shows the kinematic viscosity of the selected liquid (in centi-stokes). The
viscosity value is particularly important for high viscosity liquids. The meter requires an accurate liquid
viscosity to compute the flow profile compensation. If the displayed viscosity is correct, bypass this menu
cell by pressing the <Down Arrow>.
To edit the Viscosity setting:
To activate numeric entry press
Use PC numeric keys or Magnetic Wand to enter the Viscosity value, which must be in centistokes.

How to Edit the Density (SG) Setting
Use the [Density SG] menu cell to edit the nominal specific gravity of the selected liquid. This mode suits
applications where the density is not only known, but also fixed, due to well-controlled liquid temperature
and chemistry.
The default specific gravity setting is 1.000. The FUH1010PVX uses the liquid’s specific gravity to form a
multiplier for the conversion to API. The API appears (in selected units) on the display screen. Density SG,
as it applies to this system, is defined as the ratio of the mass of this liquid to the mass of an equal
volume of water at 20°C or 68°F.
To edit the Density SG setting:
To activate numeric entry press
Use the numeric keys to type the Density SG value.
