 Switch-on balance, repeatedly press the
UNIT
key until the balance is in weighing mode..
 Place sinker in the upper sample dish. Wait for
stability display to appear; write down the
displayed weighing value.
 Place sinker in the lower sample dish. Wait for
stability display to appear; write down the
displayed weighing value.
The density of the test liquid is computed by applying the following formula.
G = buoyancy of sinker
Buoyancy of sinker =
Weight of the sinker in air [ A ] - weight sinker in test liquid [ B ]
From this follows:
ρ = density of sample fluid
A = weight of sinker in air
B = weight of the sinkers in test liquid
V = volume of sinker
