Bomb 1
EE Value: Displays the calculated EE value for
the corresponding Bomb 1.
Number of Runs: Displays how many runs have
been used to determine the EE value.
Relative Standard Deviation: Displays the
relative standard deviation for the series of tests
used to determine the current EE value in per-
cent of the EE value.
Bomb Fire Count: Displays the current bomb
firing count or the number of times the bomb
has been fired since it was last serviced. When
this count matches the limit set by Bomb Service
Interval, the user will be informed that the bomb
is ready to be serviced.
Name: Enables the operator to assign a unique
alpha-numeric label for the bomb ID. The ID can
be up to 8 characters.
Protect EE Value: When set to ON, protects the
EE value if the user does not wish to have the
calorimeter automatically update its own EE
value.
Update Statistics: This key will cause the EE
value for this bomb ID to be updated using the
most recent standardization runs; if the EE value
is not protected. (The number of standardiza-
tion runs used is equal to the value entered into
the Calibration Data and Controls Menu under
Calibration Run Limit. If less runs are available
than the number specified, all runs will be used.)
Charted Value: Toggles the charted value be-
tween the HOC Standard (Heat Of Combustion
of Standard) and Energy Equivalent.
Process Sigma: In relation to calorimetry, sig-
ma is used as the classification of the instru-
ment. The higher the process sigma the higher
the limits for acceptable values for precision
control.
Note: The 6200 is a .1 Process Sigma calo-
rimeter.
Temp. Rise High Warning: Sets the high warn-
ing limit on the bucket temperature rise. A
temperature rise higher than this value will
generate a warning message.
Temp. Rise Low Warning: Sets the low warn-
ing limit on the bucket temperature rise. A
temperature rise lower than this value will
generate a warning message.
Use Bomb: Displays the bomb number of the bomb
currently installed in the calorimeter and toggles
through the four possible bomb numbers. The left
and right arrow keys are used to toggle through
the bomb identification numbers available for each
bomb.
Bomb 1 - Bomb 4: Leads to sub-menus for Bomb
1 - Bomb 4. Displays standardization information
for bomb and bucket combinations. While only one
bomb and bucket is installed in the calorimeter at
a time, a spare may be used for servicing and for
more rapid throughput. The respective EE values for
each bomb can be stored in memory.
Note: For rapid turn around between tests,
the user may wish to use two bombs. Each
bomb should be assigned a bomb number.
Set prompt for bomb ID to “ON”.
