Corrections & Final Reports
Entering Corrections and Obtaining the
Final Report
Final reports for each test can be obtained when-
ever the operator is prepared to enter any required
corrections for fuse, acid and sulfur.
When entering corrections, the user can choose
either of two methods. These are:
• Manual Entry
• Fixed Corrections
Chapter 4 - Program Installation and Control, pro-
vides the default settings used to setup the method
preferred by the user.
Refer to the Chapter 7 - Reporting Instructions,
for the steps necessary to initiate a report from the
controller.
Manual Entry
During the reporting process, the controller will
prompt the user to enter the following values:
Fuse Correction: Key in the Fuse Wire Correc-
tion and press the ENTER key. The default set-
ting for this value is to be entered in calories.
The fuse correction has two components and
these are explained in Chapter 7 - Calculations.
Acid Correction: Key in the Acid Correction
and press the ENTER key. The default setting
for this value is to be entered in milliliters of
standard alkali required to titrate total acid or
calories.
Sulfur Correction: Key in the Sulfur Correction
and press the ENTER key. The default setting
for this value is to be entered as percent sulfur
in the sample.
If fixed values for fuse, acid and sulfur are turned
OFF on the THERMOCHEMICAL CORRECTIONS
menu, then the user must manually enter the
values at the prompt.
If values for these corrections are not available, the
operator can use the SKIP key to bypass any of the
corrections. The report will remain at preliminary
status until an entry is made for fuse, acid and
sulfur.
Fixed Corrections
In many cases, fixed values for fuse and acid can
be used without introducing a significant error
since the corrections are both relatively small and
constant.
Fixed sulfur corrections can also be used whenever
a series of samples will be tested with a reason-
ably constant sulfur content.
Details for applying fixed corrections are found in
Chapter 7 - Calculations, Thermochemical Calcula-
tions section.
Any value set-up as a fixed correction will be
automatically applied and the controller will not
prompt the user for this value.
