6.1 User programs
User programs provide the opportunity to complete "made to
measure" analysis.
The "User Programs" database is empty when the instrument
leaves the factory and is used to accommodate programs created
by users for specific needs. User programs with 13 mm round
cells can only be performed with the empty cells LCW906. Here
are a few examples of entries:
• Programming of user-created procedures.
The analysis procedure must be developed first, before it can
be programmed. The user must define or determine the
program sequences, absorbance formulas, reading
wavelengths, factors, measuring range limits, etc.
• Modified tests
• Assignment of user programs to the "Favorites" menu for
frequently used tests.
• Creation of a specific selection of methods and tests.
