Control Keys
There are five control keys which always appear in the right column of the primary
displays. These keys are unavailable when they are gray instead of white.
1. Escape. This key is used to go up one level in the menu structure.
2. Main
Menu. This key is used to return to the main menu touch screen from
anywhere in the menu structure.
3. Start. This key is used to start a test.
4. Report. This key is used to access the test results stored in the calorimeter, to enter
thermochemical corrections, and to initiate a report on the display, printer or attached
computer.
5. Help. This key is used to access help screens related to the menu currently
displayed on the touch screen.
Programming
The program in the 6400 Calorimeter can be extensively modified to tailor the unit to a
wide variety of operating conditions, reporting units, laboratory techniques, available
accessories and communication modes. In addition, the calculations, thermochemical
corrections and reporting modes can be modified to conform to a number of standard
test methods and procedures. Numerous provisions are included to permit the use of
other reagent concentrations, techniques, combustion aids and short cuts appropriate for
the user’s work.
Note:
Changes to the program are made by use of the menu structure. Any of
these items can be individually entered at any time to revise the operating
program.
Default Settings
Units are preprogrammed with default settings. See Table 2 for a listing of the factory
default settings. A more in-depth explanation of these parameters is found on the
corresponding parameter group help pages. These default settings remain in effect until
changed by the user. Should the user ever wish to return to the factory default settings,
go to the Program Info and Control Menu, User/Factory Settings, touch Reload Factory
Default Settings and YES. Non-volatile memory is provided to retain any and all
operator initiated program changes; even if power is interrupted or the unit is turned off.
If the unit experiences an intentional or unintentional “Cold Restart”, the controller will
return to the last known settings.
The default parameters of the 6400 calorimeter can be changed to guarantee that the
calorimeter, when cold restarted, will always be in the desired configuration before
beginning a series of tests. Users who wish to permanently revise their default settings
may do so using the following procedure:
• Establish the operating parameters to be stored as the user default settings.
• Go to the Program Info and Control Menu, User/ Factory Settings, User Setup ID,
and enter the desired User Setup ID.
• Select Save User Default Settings
