Calorimeter Operating Instruction Manual

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

Program Installation and Control,

Chapter 4, provides the default settings
used to setup the method preferred by the
user.

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

Key in the Fuse

Correction Correction and press the

ENTER key. The default setting
for this value is to be entered in
calories. This is explained in
Appendix B, Page B-2.

Acid

Key in the Acid Correction

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

Key in the Sulfur Correction

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.

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 or spike if used.

After the last entry has been made,

the calorimeter will automatically produce a
Final Report.

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.
