Additional Functions
Bottom Hook Weighing
• There is a hole at the bottom of the balance for the weighing hook.
• It is not allowed to use the bottom part to balance in legal metrology.
• Open the bottom cover of the balance
• Important Notice: Please lay the side of the balance downwards to open the
bottom cover, do not make the upside down.
• To use the hook in the accessories: screw the hook clockwise in the bottom
tapped hole. Stop at once to proceed if there is any resistance.
• Adhere the goal object to the bottom hook with a line – a suspension line, for
example.
• If necessary, set a safety guard to avoid air current.
Density Measurement
Purpose:
This function is used to test the density of solid object with bottom weighing and
buoyancy theory.
Application of Formula:
Sample Density = Liquid Density*Mass in Air/
（
Mass in Air – Mass in Water
）
As the liquid density varies with different temperatures, please measure the liquid
temperature with the temperature meter and calculate the sample density with the
right water density value.
Example: Testing the sample solid density with water as the buoyancy liquid.
The water density under 20
℃
is 0.99823g/cm3.
Procedure Key/Instruction Display
a) Hang the sample solid with the suspension line
b) Press the Tare key Tare 0.00g
