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

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.
