APPLICATION FUNCTION MODE
A glass sinker for which the volume is already known is used for liquid specific gravity measurement.
The sinker weight is first measured in air, then the weight is measured in liquid, and the density of the
liquid is determined. The density is calculated by the balance software from the difference in mass found
from buoyancy.
For the following procedures, use of the optional SMK-501 specific gravity measurement kit allows for
easier measurement of specific gravity. Refer to the kit instruction manual for usage methods.

Glass Sinker Volume Measurement
If the volume of the glass sinker is not known, the volume can be calculated using the following
procedure.
1
Fill the water tank with water which
has reached a stable temperature
and measure the temperature
using a temperature gauge.
2
Enter weighing mode and press
if zero is not displayed.
3
Lower the sinker and the sinker's
weight in air will be displayed.
4
Wait until the stability mark is
displayed, then press .
