16.3 Density determination
16.3.1
Specific measurement of solid weight
In the case of specific measurement of solid weights, the sample (solid) weight is
measured in air as well as in the liquid with known density and the sample density is
calculated on the basis of that results. The ▼ symbol presents the solid density on
this balance. Density determination with the help of the flush-mounted platform
facility is described in the following.
Density determination becomes even easier when an optional set for density
determination is applied. For further information please refer to the operating
instructions enclosed with the set for density determination.
Select the menu element
60
in the menu overview.
•
From the below table (chapter 16.3.2) enter the density value (g/cm³) of the
liquid (water, alcohol etc.) in which the sample is immersed. (Entering
numerical values, refer to chapter 11.4, setting decimal point, refer to chapter
11.7). To write off the setting, zero the value.
•
Remove the cover of the hook for underfloor weighing in the balance bottom.
•
Attach the scale pan to be hung on the hook and immerse it in the container
filled with the liquid with known density.
•
Restore the weighing mode with the
ESC
ON/OFF
button and repeatedly press the
UNIT
key until the „▼d” (inverted triangle and „d”) symbol is displayed.
•
Press the
TARE /
button
•
Place the sample on the weighing plate. (If necessary, the „dSP oL” symbol
will be displayed, which does not indicate any disturbance.)
•
When the stabilisation display is illuminated, press
MENU
CAL
button.
•
Place the sample on the scale pan to be hung. The density of the sample is
shown.
Notes:
•
4 positions after the point is displayed for the specific weight. If it is not
possible to stabilize the balance with all four positions after the point, use the
1d/10d switch over function (refer to chapter 12.8).
•
If the sample lies on the scale pan immersed in the liquid, make sure that the
whole sample is immersed in the liquid.
•
The balance is not zeroed again if the
TARE /
key is pressed within this
function.
