Note: For rapid turn around between tests,
user may wish to use two bombs. Each bomb
should be assigned a bomb number. Set
prompt for bomb ID to “ON”.
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 rela-
tive standard deviation for the series of tests
used to determine the current EE value in percent
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 service.
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 iwf the user does not wish to have the calo-
rimeter 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 standardization
runs used is equal to the value entered into the
Calibration Data and Controls Menu under Cali-
bration Run Limit. If less runs are available than
the number specified, all runs will be used.)
Manual EE Entry: This key allows the user to
manually enter an EE or calibration factor for a
given calorimeter ID or bomb head. If an EE value
is manually entered, it is necessary to turn the
Protect EE Value ON in order to prevent this value
from being overwritten by an automatic update.
Print Standardization Runs: Will print all of the
tests that have been incorporated into the calcu-
lated EE value. This will be helpful in evaluating a
series of tests which fail to produce a satisfactory
EE value and relative standard deviation.
Reset Bomb Fire Count: After bomb service, press
this button to reset the fire count to zero
Control Chart Plot: Displays the current standard-
ization runs being used to calculate the Bomb EE
Value. The display will either chart the value of
the Heat of Combustion (HOC) of the Standard
or the Energy Equivalent (EE) depending on the
selection on the Control Chart Parameters menu
(see Calibration Data and Controls menu).
You can display the information used for each test by
selecting the appropriate green dot.
