Prerequisite checking for a measurement
When checking the preconditions for a measurement using a
distinction is made with and without C1.20 heating between. The
following points should be checked:
• Existing Ignition
• Sufficient oxygen present
• Open water connection
• Tempered water or using a heating their functionality
• Ignition:
Checking whether ignition contact available
• Oxygen pressure:
Check whether the system has sufficiently high oxygen pressure
has to make a measurement
• Water detected:
Check whether the system has detected water
• Limit ≤ Water ≤ Start temp:
Check whether there is the current water temperature within the
permissible temperature range
Without
C1.20
heating:
To increase the service life of wearing parts (O-rings, seals,
etc.) it is advisable to always work with a water template.
Generally, the test sample must be selected so that the tempe-
rature elevation during the measurement is below 10 K and
the temperature increase of the calibration comes close (max.
energy input: 40.000 J). Such exposure may damage the
calorimeter.
When exceeding the maximum energy input is recommended
to return the calorimeter.
To determine the potential energy initially very small sample
weights (approx. 0.2g) must be chosen when working with
unknown substances. If you burn unknown samples, leave
the room or keep your distance from the calorimeter.
If distilled water or solutions presented in the decomposition
vessel during the combustion experiment, the calibration
with the same template must have been performed before.
• Heater test:
Check the heating functionality
With
C1.20
heating:
Close the calorimeter
After the sample is loaded and the contact with the ignition wire
is present and the inner vessel was placed, the calorimeter is
sealed.
The following screen informs the user whether the system is
closed properly and securely.
Are combustion vessel and the complete system properly closed,
the measurement starts automatically.

Note:
Can the inner container and / or closure ring with handle heavy
wire, please follow the instructions for oiling the seals! (Page 74)
