Final reports for each test can be obtained whenever 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 •
Refer to the Reporting Instructions, Chapter 7, for the
steps necessary to initiate a report from the controller.

During the reporting process, the controller will prompt
the user to enter the following values:
Fuse Correction
Key in the Fuse Wire Correction and press the
ENTER key. The default setting for this value is to
be entered in calories. The fuse correction has two
components and these are explained in Appendix B.
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 Page, then the user
must manually enter the values at the prompt.
If the Spiking Correction is used, a spiking correction
must be entered before obtaining a Final Report.
After the last entry has been made, the calorimeter will
automatically produce a Final Report.
If values for these corrections are not available, the
operator can use the SKIP key to bypass any of the
corrections; however, a Final Report will not be printed
until an entry is made for fuse, acid and sulfur.

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 reasonably
constant sulfur content.
Details for applying fixed corrections are found in
Appendix B, Thermochemical Calculations.
Any value set-up as a fixed correction will be
automatically applied and the controller will not prompt
the user for this value.
