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 satisfac-
tory 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 dot.
Bomb 2: Accesses sub-menu, Bomb 2. Provides the
same controls as described for Bomb 1.
Bomb 3: Accesses sub-menu, Bomb 3. Provides the
same controls as described for Bomb 1.
Bomb 4: Accesses sub-menu, Bomb 4. Provides the
same controls as described for Bomb 1.

Standardization Correction
Fixed Fuse Correction: Displays both the ON/OFF of
the fixed fuse corrections for standardization runs
and the value of the correction. This key toggles
the correction ON/OFF and accesses a sub-menu
on which the value is set. An appropriate fixed fuse
value is 50 calories for the 1108P style bomb.
Acid Correction: Press this key on the LEFT side
to toggle between Fixed HNO
3
, Calculated HNO
3
,
Entered Total, Entered HNO
3
, and Fixed Total for the
acid correction for determination runs. Press it on
the RIGHT side to access the Acid Correction nu-
meric dialog box on which the value can be set.
Options for the Acid Correction:
» Fixed HNO
3
» Calculated HNO
3
» Entered Total
» Entered HNO
3
» Fixed Total
These options are discussed further in Appendix B -
Calculations.
Fixed Sulfur Correction: Displays both the ON/OFF
of the fixed sulfur corrections for standardization
runs and the value of the correction. This key toggles
the correction ON/OFF and accesses a sub-menu on
which the value is set. When benzoic acid is used as
the calibrant, a fixed sulfur value of zero should be
used.
