9.2 The keyboard and screen
Before starting up the machine, it is recommended to become familiar with the viscometer controls seen in
the previous section. The instrument has a 6 capacitive keyboard (Fig. 6) and a 4-lined Alphanumeric Display
screen (Fig. 2, number 1) on the frontal part ready to use and they allow the user to interact with the
machinery. The screen always shows the operations that the user is carrying out by showing menus that will
be explained later on. The measurements collected by the instrument will also be explained in this manual.
The keyboard gives the user the mobility throughout all of the menus, the selection of different options and
the creation and/or modification of viscosity measurement configurations to suit the user’s needs.
