Sample temperature (50...300°C)
Temperature to which the sample is heated.
Unit for display of the gas flow (mL/min, L/h)
All displays and entries for the gas flow depend on the
selected unit.
Minimum gas flow (0...999 mL/h or 0...59.9 L/h)
The automatic determination can be started only when the
set minimum gas flow has been reached.
Selection of the carrier gas type (air, N2, other) or selec-
tion of the gas for moisture determinations in gas
If "other" is selected, the factor for the gas flow measure-
ment must also be entered. The following values can be
used as a basis for the factor:

Purge time (0...99 999 s)
Wait time before the heating time, i.e. before the boat is
slid into the oven. The valve remains on "PURGE".
The wait time can be aborted with <QUIT>.
The purge time should be used only when the cold sample
evolves moisture with difficulty.
Conditioning time (0...99 999 s)
Wait time before the sample heating, i.e. before the boat
is slid into the oven. The valve is switched to
"TRANSFER".
The wait time can be aborted with <QUIT>.
The conditioning time should be used only when the cold
sample evolves moisture with difficulty.
Contains the parameters for the automatic determina-
tion. *live means: These parameters can be edited
during the automatic determination.
