Operating instructions

The “Density” application
119
After you have tared the sinker you are prompted to pour the liquid whose density you want
to determine into a container. If you are working with the optional density kit, follow the
instructions supplied with the kit. If you are working with the below-the-balance hanger,
place the container with the liquid under the hanger. In either case, make sure that the
sinker is immersed by at least 1 cm in the liquid, and that there are no air bubbles in
the container.
The buoyancy which the sinker experiences is displayed with a minus sign in the bottom
left corner of the window.
Press “OK” to accept the weight value.
The balance now determines the density of the liquid and displays the result. Either the
compensated result, the uncompensated result, or both is/are displayed depending on
the settings you made for the result display (see section 10.3.5).
If a printer is connected, you can press the «F» key to print out a report of the density
determination result according to your specifications (section 10.3.8). The result is saved
until the next density determination using the same method has been completed, so it
can be printed out again if required.
10.4.3 Density determination of pasty substances using a gamma sphere
To determine the density of pasty substances, use is often made of a gamma sphere whose volume is known. The pasty substance is
first tared without the gamma sphere and then with it.
In the application-specific settings for the method, select “Pasty Substance” (section
10.3.2).
Activate the appropriate function keys and information fields (sections 10.3.6 and
10.3.7). The example at left shows settings for the density determination of pasty substances
using a gamma sphere. Note: The “Temp. AL” function key which is shown activated in
the example at left, as well as the information field with the same name, is not required
for this method of density determination. If you wish, however, you can use this function
key to enter the current ambient temperature so it is printed on the report as a record of
the temperature at which the density was determined.
Press the “Vol. G. Sphere” function key and enter the volume of the gamma sphere (in
this example 10.00000 cm³).
Press the “Start” function key to start the density determination. You are then prompted
to place the sample on the balance (without the gamma sphere).
The weight of the sample is displayed in the bottom left corner of the window.
Press “OK” to tare the sample.
