F Shortcut Keys
You can declare which particular weighing function is to be launched using F1, F2, F3 or F4 keys.
For procedure informing you how to declare the particular function, read F Shortcut Keys section.
11.8.1. Density Determination
Density determination of solids can be carried out by means of two pre-defined types of liquids or
user-defined liquid of specified density:
•
WATER (distilled water),
•
ETHANOL (spirit 100% +/- 0.1% in temp. 20
•
OTHER (another liquid of specified density).
When determining density in water or alcohol it is necessary to specify their temperature. For liquid of
specified density, its value (density) is inserted from balance keyboard. Density determination is
carried out by weighing a sample first in the air (top weighing pan (4) of the density kit), and then
weighing the same sample in liquid (on the bottom weighing pan (2) of the density kit). As the same
sample is weighed in liquid, the result of density determination is automatically indicated on
a balance display.
In order to determine the density you need to:
3. Install the density determination kit.
4. Enter <SOLIDS DENSITY> function.
5. Prepare a sample.
6. Initiate the process.
7. Set the process following the displayed messages.
8. Select liquid in which the determination is to be carried out.
9. After selecting and entering a liquid type by pressing <ENTER> button, the software proceeds
to setting the liquid temperature.
10. If <OTHER> liquid of determined density has been chosen, enter its density.
11. With this data entered, the program proceeds to weighing.
12. First, place a mass sample on the top weighing pan of the kit (weighing in the air), and confirm
the indication when stable.
