Operation
In its Dynamic Operating Mode,
the calorimeter uses a sophisticated
curve matching technique to compare the
temperature rise with a known thermal
curve to extrapolate the final temperature
rise without actually waiting for it to develop.
Repeated testing, and over 20 years of
routine use in fuel laboratories, has
demonstrated that this technique can cut
the time required for a test by one-half
without significantly affecting the precision
of the calorimeter.
The microprocessor controller in
this calorimeter has been
preprogrammed to automatically
prompt the user for all required data
and control input and to:
A. Generate all temperature readings in
the calorimeter.
B. Monitor jacket as well as bucket
temperature.
C. Confirm equilibrium conditions.
D. Fire the bomb.
E. Confirm that ignition has occurred.
F. Determine and apply all necessary
heat leak corrections.
G. Perform all curve matching and
extrapolations required for dynamic
operation.
H. Terminate the test when it is
complete.
I. Monitor the conditions within the
calorimeter and report to the user
whenever a sensor or operating
condition is out of normal ranges.
In addition to its process
control functions, the
microprocessor in the
calorimeter has been
preprogrammed to:
A. Collect and store all required
test data.
B. Apply all required corrections for
combustion characteristics.
C. Compute and report the heat of
combustion for the sample.
The fifth generation software
built into this calorimeter and
accessed through the screen menus
permit the
user to customize the operation of the
calorimeter to meet a wide variety of operating
conditions including:
A. A large selection of printing options.
B. Choice of accessories and peripheral
equipment.
C. Multiple options in regard to handling
thermochemical corrections.
D. Choice of ASTM or ISO correction
procedures.
E. A variety of memory management and
reporting procedures.
F. Complete freedom for
reagent concentrations and
calculations.
G. Unlimited choice of reporting
units.
H. Automatic bomb usage
monitoring and reporting.
I. A choice of Equilibrium or
Dynamic test methods.
J. Automatic statistical treatment of
calibration runs.
K. Enhanced testing and trouble
shooting procedure.
The 6200 Calorimeter is equipped with
two RS232C connections for direct
communication with its printer and an
attached balance. It is also equipped with
an Ethernet network connection for
connections to laboratory computers.
