The combustion experiment is
lasting too long. Isoperibolic
measurements are stopped after
13 minutes in the “Stabilize”
phase or after 16 minutes in the
main experiment.
Check:
• the operation of the stirrer drive
(Maintenance menu: 6WLUUHU
RQRII ).
• temperature equalization of the
calorimeter to the working tem-
perature with the Maintenance
menu: 7HPSHUDWXUH HTXDOL]DWLRQ
• The seal of the decomposition
vessel (see C 5010/C 5012 Op-
erating Instructions).
!! 7HPSHUDWXUH [[[[ ƒ& Malfunction while recording the
temperature
The temperature display does
not change any more.
Open the information window and
look at the temperature displays
7HPS and 7HPS . If Temp1 or
Temp2 do not change within 60 sec-
onds, there is an error in tempera-
ture recording.
Both values are constant: In the
Maintenance menu, execute the
7HPS ,QLW command.
If you cannot reach the Maintenance
menu or if you do but this does not
provide any help, turn the calorime-
ter off and back on again.
Only Temp2 is constant: In the
Maintenance menu, execute the
&RROLQJ ZDWHU command. After 60
seconds at the most, the displayed
cooling water temperature should no
longer be constant. If you cannot
reach the Maintenance menu or if
you do but this does not provide any
help, use another method to check
the cooling water temperature. The
cooling water temperature must fall
within the range of 5.xx°C to 28°C
before it is possible to continue
working.
