Readjustment

To ensure accurate results it is necessary to clean the measuring cell before and after each
measurement series. If the measuring cell is not sufficiently cleaned, residue can form in the measuring
cell. This can be noticed if the density values for deionized water begin to deviate. Therefore, perform
regularly check measurements with deionized water.
If the density values for water deviate by more than ±0.001 g/cm

3

at the given temperature from the

table values (see Appendix A), then a readjustment is required. A readjustment is only possible if the
calculated difference between the measured and the theoretical value is smaller than 0.01 g/cm3 and
the temperature of the water is between 15 and 25

º

C.

12.1 Check Measurement

1.

Clean the measuring cell as described in Chapter 10.1 and rinse the measuring cell until no more

solvent residues are present.

2.

Select the measuring unit “Density” (see Chapter 9.1).

3.

Fill the measuring cell with deionized water and perform a measurement (see Chapter 9.5

and 9.6).

4.

Compare the measured density value with the table values (see Appendix A).

5.

If the measured density value deviates more than 0.001 g/cm

3

from the table value, perform a

readjustment.

12.2 Water Adjustment

One option is to readjust using deionized water.

1.

Clean the measuring cell as described in Chapter 10.1 and rinse the measuring cell until no more

solvent residues are present.

2.

Press <Menu> and select “Adjustment > Water Adjustment”.

3.

Fill the measuring cell with deionized water at approximately 20

º

C (15 to 25

º

C) without bubbles.

4.

Confirm with <OK> that the measuring cell is filled with deionized water.

The density value of the filled deionized water is now measured and compared with the

adjustment data. The display shows the calculated deviation (Delta) in g/cm

3

.

5.

Press <OK> to activate the new adjustment.
