After the system has been switched on and you have acknowledged the opening
screen with 2. , it requires about 30 minutes until the stable temperature conditions
are prevalent in the measurement cell.
Before a measurement is started, the system must have previously been calibrated
as described in Section 9 “Calibration”.
c
The decomposition vessel must be clean and dry. See item 10.4. If necessary, a
measured amount of distilled water or a solution must be placed in the decomposi-
tion vessel. Substances with low inflammability are weighed into the crucible with a
combustion aid. The heat of combustion from the combustion aid must be known.
Note in this regard Section 10.1 “Notes on the sample”. Prepare the decomposition
vessel as described in Section 9.1 “Charging the decomposition vessel with the cali-
bration substance”. Instead of the calibration substance, the decomposition vessel is
charged with a representative sample of the substance to be examined.

If you are using a combustion aid, you must add the energy from the combustion aid
and enter it into the energy entry in the 6DPSOH dialog box in the 4([WUDQ box, or
else use the appropriate scale mode :LWK FRPEXVWLRQ DLG
If a scale is used in the :LWK FRPEXVWLRQ DLG mode and the weight of the combustion
aid is previously transferred, the extraneous energy calculated from the weight ap-
pears in this box.
