13.2 Solid Specific Gravity Measurement
Solid specific gravity measurement computes the density (or specific gravity) of a solid
sample by measuring its weight in air and in a liquid of known density (or specific gravity).
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 or specific gravity can
be done even more easily with an optional specific gravity measurement kit.
When using the kit, follow the instruction manual provided with the lkit.
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 liquid of the tank.
3 Register “,d” (the solid specific gravity) as a
unit, referring to 12.1.
4 Input the density of the liquid to be used for
solid specific gravity measurement.
(a) Press the
[CAL]
key repeatedly from the
mass display until the “SEttinG” appears.
Press the [O/T] key. The display shows
“CAL dEF”.
(b) Press the
[CAL]
key repeatedly until
“LSG SEt” appears and press the
[O/T]
key.
MENU The symbol and the # symbol
appearing in the upper part of the display panel
indicates it is numerical entry mode.
Also “SG*.****” appears
(where the *.**** is a number).
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 digit and move the blinking digit one
place to the right. When the desired setting is
entered, press the
[O/T]
key to confirm the
density of the liquid to be used, or
(d) Press the
[POWER]
key to abort the setting
and return to the “LSG SEt” display.
(e) Press the
[POWER]
key repeatedly to return to
the mass display.
