Section 9: The “Density” Application

If you use an auxiliary liquid other than water or ethanol, activate the function key

“Density AL” and use this key to enter the density of the auxiliary liquid being used

at the current temperature. This is necessary because there are no density tables in

the balance for liquids other than water and ethanol. The value entered appears in the

information field with the same name, which you should also activate. Note: In the

example at left, the activated function key “Temp. (AL)” is not required for density

determination using an auxiliary liquid other than water or ethanol. However, you can

use this key to enter the current ambient temperature, which can then be printed out on

reports and shows the temperature at which the density result was determined.

Touch the «1» key on the terminal to tare the balance.

Touch the “Start” function key to start the density determination. After a short pause you

will be prompted to place the solid on the weighing pan (weighing in air).

If you are working with the below-the-balance hanger, hang the solid on the hanger. If

you are working with the optional density kit, follow the instructions supplied with the

kit.

The weight of the solid on the weighing pan appears in the lower left corner of the

window.

Touch the “OK” key to accept the weight value.

After a short pause you will be prompted to place the solid in the auxiliary liquid.

If you are working with the below-the-balance hanger, place the container with the

auxiliary liquid below the hanger. If you are working the optional density kit, follow the

instructions supplied with the kit. In either case, ensure that the solid is immersed at least

1 cm in the liquid and that there are no air bubbles in the container.

The weight of the solid in the liquid appears in the lower left corner of the window.

Touch the “OK” key to accept the weight value.

The balance now determines the density of the solid, and you will then be asked whether

you wish to accept the result of the density determination into the statistics.

Touch the “OK” key to accept the density value into the statistics. If you do not wish to

accept the result into the statistics, touch “Cancel” instead. The result is then held until

the next measurement and is shown in the “Density” information field, but it is not

accepted into the statistics.

You will find information about using the density statistics in Section 9.5.3.

You can use the «8» key to print out the result of the current density determination.

You will find an example of a report and corresponding explanations in Section 9.5.2.
