You have the following input options:

1) You can directly enter the density of a liquid. In this case, you will not

be prompted to enter a temperature (1st function). Enter density using the

numeric keys; press F to store.

2) You can enter the density of a liquid at 20°C and the volume expansion

coefficient. During density determination, you will then be prompted to enter

the temperature (2nd function) (see example below).

Practical Example: Entering the Density and the Expansion Coefficient

Procedure/conditions: Ethylene glycol at 23°C will be used as the liquid into

which the samples will be immersed. Its density at 20°C

is1.113 g/cm

; its volume expansion coefficient at 20°C

is 0.00064 K
