Operation
Menu System
All confi gurations and operations are handled by a
menu-driven system operated from the bright touch
screen display. The settings and controls are orga-
nized into eight main sections as displayed on the
MAIN MENU.
Note: Keys with a “double box” in the upper
left hand corner lead to sub-menus.
Menu Keys
The controls that change the data fi eld information
in the menus will be one of the following:
1. Toggles. These data fi elds contain ON/OFF or
YES/NO choices. Simply touching the key on the
screen toggles the choice to the other option.
The current setting is displayed in the lower
right corner of the key.
2. Option Selection. These data fi elds contain a list
of options. Touching the key on the screen steps
the user through the available choices. The cur-
rent setting is displayed in the lower right corner
of the key.
3. Value Entry Fields. These data fi elds are used
to enter data into the Calorimetric Thermom-
eter. Touching the key on the screen brings up a
sub-menu with a key pad or similar screen for
entering the required value. Some keys lead to
multiple choices. Always clear the current value
before entering a new value. Once entered the
screen will return to the previous menu and the
new value will be displayed in the lower right
corner of the key.
4. Data Displays. Most of these keys display values
that have been calculated by the Calorimetric
Thermometer and are informational only. Cer-
tain ones can be overridden by the user entering
a desired value through a sub-menu. The value
is displayed in the lower right corner of the key.
Note: Some keys will respond with an opportu-
nity for the user to confi rm the specifi ed action
to minimize accidental disruptions to the program
and/or stored data.
Control Keys
There are fi ve 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 Calorimetric
Thermometer test.
4. Report. This key is used to access the test re-
sults stored in the Calorimetric Thermometer, to
enter thermochemical corrections, and to initi-
ate 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.
6. This key appears in the Escape key location
when the main menu is displayed. This key is
used to shut down the calorimeter program be-
fore turning off the power.
Programming
The program in the 6772 Calorimetric Thermom-
eter can be extensively modifi ed to tailor the unit
to a wide variety of operating conditions, reporting
units, laboratory techniques, available accessories
and communication modes. In addition, the calcu-
lations, thermochemical corrections and reporting
modes can be modifi ed 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.
