Menu Descriptions
Note: Keys which make global changes to
the setup of the calorimeter contain a YES or
NO response to make certain that the user
wishes to proceed. This two step entry is
intended to prevent inadvertent global pro-
gram changes.
Main Menu
System Shutdown: This key appears in the
ESCAPE key location when the Main Menu is dis-
played. Pressing this button will prompt the user to
confirm a system shutdown.
Escape Key: Selecting the Escape key on any menu
will return you to the menu one level up.
Main Menu Key: Selecting the Main Menu key on
any menu will return you to the screen pictured on
the right of this page.
Start Key: Press the Start key to begin any Determi-
nation or Standardization run.
Report: Press the Report key to begin the reporting
process.
Help: Press the Help key on any screen to display
the explanation text for that screen.
Abort: This key appears in the Start key location
while a test or pretest is running. Pressing this key
will abort the test or pretest in progress.
Calorimeter Operation Menu
The Calorimeter will normally be operated from the
Calorimeter Operation Menu, although tests can
always be started from any menu screen.
Operating Mode: Sets the operating mode by
toggling between Standardization (for instrument
calibration) and Determination (for test runs).
Temperature Graph: Press this key to display a real-
time plot of the bucket and/or jacket temperature on
the Temperature vs. Time Plot screen.
Bomb/EE: Used to identify the bomb presently
installed in the Calorimeter and its EE value.
Start Preweigh: This key is used to start the sample
pre-weigh process. The user is presented with or
prompted for a sample ID. Next, the user is asked to
key in the associated sample mass or alternatively
the mass is retrieved from a connected balance or
network.
Heater and Pump: The heater and pump must only
be turned on after the calorimeter water tank is filled
with water.
Note: The heater and pump must be turned
ON to bring the jacket to the correct starting
temperature before testing can commence.
Start Pretest: This key is used to initiate a pretest
cycle. A pretest will cycle the calorimeter through
the fill and cool/rinse process. This function is used
to pre-condition the calorimeter.
