To program or edit a user table
If you have a literature table or own experimental data about the density of a
binary mixture at different concentrations, you can program this data into a user
table.
TIP
•
The larger the number of data pairs and the higher the accuracy of the data
pairs, the higher the accuracy of the results that you can obtain with your
user table.
•
Your M series instrument will interpolate, but not extrapolate. This means,
that the data pairs that you enter into the instrument should cover the whole
range of values that you want to measure.
