Liquid Specific Gravity
Liquid specific gravity is calculated using values obtained by measuring the
weight of the sinker (solid of known volume) in the air and in the sample
liquid. The display unit for liquid specific gravity is
"d."
Procedure
(1) Place the optional liquid sample sinker in a tank containing the
sample liquid.
(2) Register the liquid specific gravity unit.
F
See Section
10. “REGISTRATION, RELEASE, AND
SELECTION OF MEASUREMENT UNITS.”
(3) Set the sinker volume for the measurement of liquid specific
gravity.
(4)
F
See Section
24. “SINKER VOLUME FOR LIQUID SPECIFIC
GRAVITY MEASUREMENT.”
(5) Press the UNIT key from the mass display and select
"d"
. While
measuring the mass of the sinker in the air, the g unit is also
illuminated.
(6) Press the

key.
(7) Place the sinker on the upper pan of the optional SMK-301.
(8) Press the CAL/MENU key when stability symbol illuminates.
(9) Next, place the sinker on the pan in the liquid. The display indicates
the specific gravity of the sample.
(10) Start the measurement of the next sample from step (5).
