2 Move the navigation joystick upwards and let go.
ð The sample pump starts and stops when the piston is
in the uppermost position.
3 Lift the filling tube out of the cleaning solution and hold it
over the waste beaker (2).
4 Move the navigation joystick downwards and let go.
ð The sample pump starts and stops when the piston is
in the lowermost position.
5 Clean the end of the filling tube with a clean tissue.
6 Repeat the steps until all residue from the sample is
removed.
7 Move the navigation joystick upwards and let go.
ð The sample pump fills the measuring cell with air.
8 Move the navigation joystick downwards and let go.
ð Most of the cleaning solution is removed from the
measuring cell.
9 Clean the end of the filling tube with a clean tissue.

6.3 Check the measurement accuracy

To check the measurement accuracy of the density meter, you need to configure and perform a test.
You can find more information about the configuration of a test in the Reference Manual.

6.3.1 Example: Test with water

The following chapters show you how to configure and perform a guided test with deionized water at room
temperature (23 °C or 73.4 °C).

Explanation
The density meter prompts users to fill and drain the
measuring cell.
The density meter uses predefined values for the water
measurement.
The density meter prompts users to enter the identifi-
cation before the density is measured.
The density meter prompts users to fill and drain the
measuring cell twice and then fill the measuring cell for
the measurement.
The pump fills the measuring cell with 80 % of the
maximum pump speed.
