The decomposition vessel is vented and the measurement cell cover opens.

As soon as the message %RPEn appears, remove the decomposition vessel and

open it.

Check the crucible for combustion residue. Both the cotton thread and the fuel sam-

ple must have been burned completely. If there are any signs of incomplete com-

bustion, the experiment must be repeated.

It is of fundamental importance for the decomposition vessel to be clean and dry.

Contamination can change the heat capacity of the decomposition vessel and result

in imprecise measurement results. After each combustion experiment, the inner

walls of the vessel, the inner fittings (supports, electrodes, etc.) and the combustion

crucible (inside and outside) must be thoroughly cleaned.

In most cases, condensation must simply be removed from the inner walls of the

vessel and the inner fittings. It is sufficient to carefully wipe off the parts with an ab-

sorbent cloth that will not leave lint.

If the decomposition vessel cannot be cleaned with the procedure described (for

example because of burned or corroded spots), you should contact the Technical

Service Department.

The combustion residue in the crucible, for example soot or ash, should also be

carefully wiped off with an absorbent cloth that will not leave lint.
