Operation
Menu System
All configurations and operations are handled by
a menu-driven system operated from the bright
touch screen display. The settings and controls are
organized into ten 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 field information
in the menus will be one of the following:
1. Toggles. These data fields 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 fields 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 fields are used to
enter data into the Calorimeter. 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 calorimeter
and are informational only. Certain 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 op-
portunity for the user to confirm the speci-
fied action to minimize accidental disruptions
to the program and/or stored data.
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. Abort. When a test is running the Start button
changes to Abort. When pressed it will terminate
the current test or pre-test.
5. Report. This key is used to access the test re-
sults stored in the calorimeter, to enter thermo-
chemical corrections, and to initiate a report on
the display or printer.
6. Help. This key is used to access help screens
related to the menu currently displayed on the
touch screen.
7. This key appears in the Escape key loca-
tion when the main menu is displayed. This key
is used to shut down the calorimeter program
before turning off the power.
