The measurement proceeds fully automatically until the final result. If the measure-
ment needs to be interrupted, a message window appears that can be acknowl-
edged by the user. (See Section 12, “Troubleshooting”).
e
If necessary:
You can interrupt the experiment at any time with &DQFHO .
’
If the measurement is complete or has been interrupted, the measuring cell cover
opens and the inner vessel is emptied. As soon as the message %RPE Ï appears in
the footer, you can remove the decomposition vessel.
“
Pressure can be released from the decomposition vessel with the venting button by
using a laboratory discharge hood or with the C 5030 venting station available as an
accessory.
h
Open the decomposition vessel and check the crucible for signs of incomplete com-
bustion. If combustion was incomplete, the results of the experiment must be dis-
carded. The experiment must be repeated.

It is of fundamental importance for precise measurements for the decomposition
vessel to be clean and dry. Impurities will change the heat capacity of the decompo-
sition vessel and cause the results of the measurement to be inaccurate. After every
combustion experiment the walls of the vessel, the inner fittings (holders, electrodes,
etc.) and the combustion crucible (inside and outside!) must be cleaned thoroughly.
In most cases, all that is necessary is to remove condensation from the inner walls
of the vessel and the inner fittings. It is sufficient to wipe off the parts carefully with
an absorbent lint-free cloth.
If it is not possible to clean the decomposition vessel with the measures described
(for example singed spots, pitting, corrosion, etc., you should call the Technical
Service Department.
The residue of combustion in the crucible, for example soot or ash, can also be
wiped out with an absorbent and lint-free cloth.
