6772
Calorimetric Thermometer Instruction Manual
5-9
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:
Toggles between OFF and ON. When set to OFF, the 6772 automatically updates the
EE value as new tests are run. When set to ON, it keeps the EE value protected,
whether it has been revised manually via the Manual EE Entry key or calculated by the
instrument.
Update Statistics:
If the Protect EE Value is set to OFF, pressing this key will cause the EE Value for
this Calorimetric Thermometer to be updated using all standardization runs currently
in memory. If the Protect EE value is set to ON, this key is not functional.
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 or manual update.
Print Standardization Runs:
Will print all of the tests that have been incorporated into the calculated 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 key to reset the fire count to zero.
Control Chart Plot:
Displays the current standardization
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.
