Air Dried Loss or Total Moisture Entry
Air Dried Loss (ADL) or Total Moisture (TM)
weights are identifi ed with the corresponding key. A
report fi le can contain ADL or TM data but not both.
Entering one kind of data excludes the other from
being entered unless the other is cleared by editing
the report. The total moisture value is numerically
equal to moisture as received.
Settings on the Data Entry and Controls page
determine the ADL and TM prompting order for
data entry. Users having a second 6750 Proximate
Interface confi gured as an ADL or TM Interface may
obtain these data from the remote interface via the
Ethernet port. Settings on the Data Entry and Con-
trols page control the source of the ADL or TM data.
The procedure for obtaining the ADL or Total
Moisture Weights from a remote interface is the
same as a manual entry procedure. To expedite
ADL or TM weights from a remote device, the rec-
ommended procedure is to press all three weight
identifi cation keys (TARE, GROSS and FINAL) before
the enter key when obtaining weights from a remote
6750 ADL or TM Interface. No information will be
sent, even if only one datum is requested, unless
all three weights have been entered into the remote
interface.
Ash Fusion Entry
Ash Fusion values are identifi ed with the cor-
responding keys. The user can choose either Ash
Fusion Oxidizing or Ash Fusion Reducing. Once this
choice is made the following four critical point tem-
perature keys are displayed.
t
IT, Initial deformation temperature
t
ST, Softening temperature
t
HT, Hemispherical temperature
t
FT, Fluid temperature
Any number of these keys can be pressed. The
Interface will then prompt for the corresponding
value(s). Typical values for this test range from 1470
F (800 C) to 2900 F (1600 C). Values are reported to
the nearest unit. The reporting units, degrees C or F,
for the critical point temperatures is set on the Data
Entry and Controls page.
FSI Entry
Pressing the FSI key will simply initiate a prompt
for a numerical value for the free swelling index of
the sample, displayed to the nearest tenth of a unit.
The typical range of values is zero to 12.
Automatic Sample ID Increment Option
The basic data entry procedure can be modifi ed
to streamline the entry of data, and to adapt it to the
individual user’s operation procedures. One method
of modifying these procedures is through the use
of the Auto Sample ID Controls. When this option is
turned on, the Interface will automatically increment
the Sample ID by the value indicated on the Auto
Sample ID Controls page and prompt for a new set
of values each time a data entry sequence is com-
pleted.
