Calorimetric Thermometer 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.
Data Log Destination:
Options are logfile, printer or both. When the logfile option is selected, the logfile is
located at /flash/datalog.csv. The maximum allowed size for this file is roughly one
megabyte. If the file reaches this size, logging is halted.
