EJ-13 Installation
Push the fixing frame out, and
remove the weighing pan.
Attach the beaker stand to the balance and fit the pan stand to the pan support of the balance.

Beaker
Place a beaker filled with water on the beaker stand and place the sample weighing pan on top of the pan stand.
Density (specific gravity) measurement
The density of a liquid can be changed and there are two ways of setting. One is to set the water temperature and the other is to set density value directly.
The factory setting for density of a liquid is 25 °C as water temperature (the density value ρ = 0.99704 (g/cm3) is used to calculate).
The density (specific gravity) is calculated by the following formula.
S = A X ρ
S:Density (specific gravity) of a sample
A:Weight in air
B:Weight in liquid
ρ: Density of liquid (water)
The result is shown with two decimal places.
