also needs to ensure the package is shaken for about 5 minutes before measuring, and to know the
total volume of the package and the total volume of the contents of the package.

measurements of small volume individual samples such as cans, bottles, etc. The measurement
mode is a parameter defined for the entire instrument, not for each channel.
