Specific Gravity (Density) Measurement - AND GR Series Instruction Manual

13. Specific Gravity (Density) Measurement

GR series balances are equipped with the specific gravity measuring mode. It calculates the density of
a solid according to the weight of the sample in air and weght in liquid.
The specific gravity measuring mode is not ready for use upon receiving the balance. To use the mode,
change the function table and activate the specific gravity measuring mode.
Two ways to set the density of a liquid are available:
by entering the water temperature and by entering the density directly.
Formula to obtain the density
The density can be obtained by the following formula.
A
ρ= x ρ
A B
ρ: Density of sample
A: Density of sample in air
B: Weight of sample in liquid
ρ : Density of liquid

(1) Changing the function table
1 Setting the specific gravity measuring mode
The specific gravity measuring mode is available as one of the units. To use the mode, select it in the
function table. For how to select the specific gravity measuring mode, see "Selecting a unit and
arranging the sequence of display" in "4. Weighing Units" (Select
2 Selecting the way to set the density of a liquid
Select the liquid density method from the function table below. The function table is available only when
the specific gravity measuring mode is selected. For how to select, see "9. Function Table".
