Semi-micro Calorimeter Instruction Manual
5-19
Diagnostics Menu
Provides the user with the means to test
many of the components and
subsystems of the Calorimetric
Thermometer. These capabilities
should be used in conjunction with this
instruction manual in order to obtain the
maximum benefits from these
capabilities.
Calorimetry Parameters:
This key accesses its sub-menu which
allows access to the calorimetry
parameters used to automatically
sequence a calorimetric test. These parameters are organized according to their
use. The three types are:
• Tolerance (L) Parameters. These parameters are used primarily to
establish appropriate criteria for transitioning from pre-period to post-period
as well as ending a test.
• Correction (K) Parameters. These parameters are used for calorimeter
temperature drift corrections.
• Blackout (B) Parameters. These parameters establish suitable blackout
criteria for the post-period of the testing sequence.
Test Ignition Circuit:
Activates the ignition circuit. A volt meter can be placed across the firing
connections to ensure that the actual firing charge is reaching these contacts.
Data Logger:
Displays ON/OFF status and accesses
the Data Logger Controls Menu for
setting the specific logging controls.
Data Logger:
This key toggles the data logging
function ON / OFF.
Data Log Interval:
This key displays the interval of
which the selected data is
logged. The interval in seconds
is defined in the Select Data
Items sub-menu (normally 10 seconds). This roughly matches the update interval
for the bucket temperature.
