13.3 Liquid Density Measurement
Liquid density measurement computes the density of a liquid by measuring the weight of a
sinker (solid) with a known volume in air and in the liquid.
The following is the procedure when using a hanging pan, a tank and a table allowing below
balance weighing, prepared by the operator. Measurement of density can be done even more
easily with an optional specific gravity measurement kit. When using the kit, follow the
instruction manual provided with the kit.
1 Remove the below-weigh hook cover on the
base of the balance, after removing the two fixing
screws.
2 Hang the user-prepared hanging pan from the
below-weigh hook and sink that hanging pan into
the sample liquid in the tank.
3 Register “d” (liquid density) as a unit, referring
to 12.1.
4 Input the sinker volume (in cm3) for liquid density
measurement.
(a) Press the [CAL] key repeatedly from the mass
display until the “SEttinG” display appears. Press
the [O/T] key. The display shows “CAL dEF”.
(b) Press the [CAL] key repeatedly until “Sv SEt”
appears and press the [O/T] key. *.****” appears
(where the *.*** is a number). The MENU
symbol and the # symbol appearing in the upper
part of the display panel indicates it is numerical
entry mode. The leftmost digit of *. **** blinks.
The blinking digit can be changed.
(c) Press the [UNIT] key to increase the value of
the blinking digit by 1. Press the [PRINT] key to
set that place and move the blinking digit one
place to the right. When the desired setting is
entered, press the [O/T] key to confirm sinker
volume (in cm3) of the sinker to be used, or
(d) Press the [POWER] key to abort the setting
and return to the “Sv SEt” display.
(e) Press the [POWER] key again to return to the
mass display.
