Use Offset Correction (ISO): The thermochemi-
cal calculations used for treatment of nitric acid
and sulfuric acid corrections in the ISO and B.
S. methods require an offset correction to com-
pensate for the back titration that is made. To
use these calculations, set to ON and enter the
appropriate value as the offset value.
Offset Value: Entry for the value when use offset
correction is turned ON.
Net Heat/Dry Heat Factors
Fixed Hydrogen: ON/OFF and value entry.
Fixed Oxygen: ON/OFF and value entry.
Fixed Nitrogen: ON/OFF and value entry.
Calculate Net Heat of Combustion: ON/OFF.
Turn On to have the calorimeter calculate the
net heat of combustion.
Fixed Moisture as Determined: ON/OFF and
value entry.
Fixed Moisture as Received: ON/OFF and
value entry.
Dry Calculation: ON/OFF. Turn on to have the
calorimeter calculate the result on a dry basis.
Data Entry Controls Menu

Acid Entry Mode: This key steps through the op-
tions for entering acid correction value either
manually through the touch screen or automatically
through the balance (USB) port.
Net Heat Entry Modes: This key accesses a menu
listing options for entering hydrogen, oxygen, and
nitrogen content for calculating the net heat of com-
bustion either manually through the touch screen or
automatically through the balance (USB) port.
Automatic Sample ID Controls: Accesses sub-menu
for controlling the automatic assignment of sample
identification numbers.
