12.3 Custom Adjustment
You can also use any other reference liquid with a known density at 20ºC and known temperature
coefficient for your readjustment.
We recommend using the customer adjustment e.g. if you measure only liquids in a specific density
range (e.g. high density) and want to yield more accurate results in this range.
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 > Custom Adjustment”.
3. Fill the measuring cell with reference liquid at approx. 20ºC (15 to 25ºC) without bubbles.
4. Confirm with <OK> that the measuring cell is filled with reference liquid.
You are asked to enter the density of your reference liquid at 20ºC.
5. Using the arrow keys, select the first number and press <OK>.
6. Repeat the procedure for the other numbers and press <Save>.
7. Enter the temperature coefficient of your reference liquid and press <Save>.
The density of the filled reference liquid is now measured and compared with the entered
density for the reference liquid at 20ºC. The display shows the calculated deviation (Delta) in
g/cm

.
8. Press <OK> to activate the new adjustment.
12.4 Defining an Offset
You can define an offset for your measurement. This is automatically added to each measured value.
The offset value always refers to the current measuring unit and is deleted when you change to another
measuring unit. If you have selected a method, the set offset is saved with the method.
1. Press <Menu> and select “Adjustment > Custom Offset”.
2. Using the arrow keys, select the first number of your offset value and press <OK>.
3. Repeat the procedure for all other numbers and press <Save>.
The set offset is now shown in the main screen.
12.5 Restoring to Factory Adjustment
If you want to undo all your adjustments you can restore the factory adjustment.
1. Press <Menu> and select “Adjustment > Factory Adjustment”.
The display shows: “Are you sure that you want to reset to factory adjustment?”
2. Press <OK> to restore the factory adjustment.
The factory adjustment is restored.
