4.3 Measurement „Density solid material“
1. Repeatedly press the UNIT/ button until the balance is in
density determination mode for solid material „
T
d". If the weight
is measured in air, additionally a „g“ will be displayed.
2. Press the TARE/ button. Place sample in the upper sample
dish.
3. When standstill control is complete, press the CAL/MENU
button.
4. Place sample in the lower sifting bowl. When standstill control
is complete, the density of the sample will be shown in the
display. Remove the sample.
May be that „oL“ will be displayed, but in that step this isn’t any
error message and can be ignored.
5. For other measurements start at step 2 by pressing the
CAL/MENU button.
4.3.1 Density determination of solid material with a density of less than 1
g/cm
3
At solid material with density less than 1 g/cm
3
, a density determination with two
different methods is possible.
Method 1:
As measuring density a liquid with less density than that of the solid material, e.g.
ethanol approx. 0.8 g/cm
3
.
This method should be applied when the density of the solid is just slightly different
from that of the distilled water.
Using ethanol is not recommended, when the solid material is being attacked.
When working with ethanol, you must observe the applicable safety regulations.
Method 2:
Here the sample is not placed upon, but under the sifting bowl. For this purpose use
the combination weighing tray (1) -2.
Ö Activate function, see chap. 4.1.
Ö Input parameter measuring liquid, see chap. 4.2.
Ö Density measurement see chapter 4.3, in step 4 place the sample under the
sifting bowl. If the buoyancy of the sample is so much that the combination
weighing tray is lifted, place a dummy weight on it and tare it away when weighing
in air.
