8.4.3 Determining the density of pasty substances using a gamma sphere
The density of pasty substances is usually determined using a gamma sphere whose volume is known. The pasty substance is
weighed first without, and then with, the gamma sphere.
In the application-specific settings select the method Gamma sphere (Section 8.3.2).
Activate the suitable function keys and information fields (Sections 8.3.4 and 8.3.5).
The example at left shows appropriate settings for determining the density of pasty
substances using a gamma sphere. Note: The function key Temp. (AL) and the
information field with the same name which are activated in the example shown at left
are not required for this method of density determination. You can, however, use them
to enter the current ambient temperature which can then be printed out on the reports
and shows the termperature at which the density result was obtained.
Touch the Vol. AL function key and enter the volume of the gamma sphere (in this
example 10.00000 cm
3
).
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 sample on the weighing pan (without the gamma sphere).
The weight of the sample 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 immerse the gamma sphere in the sample
substance.
The weight of the sample with the gamma sphere 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 pasty substance and you will then be
asked whether you wish to accept the result 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 the Cancel key instead. The result is held until
the next measurement and is displayed in the Density information field, but is not
accepted into the statistics.
You will find information about using the statistics in Section 8.5.3.
You can use the «8» key to print out the result of the current density determination.
You will find an example of a report with corresponding explanations in Section 8.5.2.
