Prerequisite checking for a measurement
When checking the preconditions for a measurement using a
distinction is made with and without C 1.20 heating between. The
following points should be checked:
• Existing Ignition
• Sucient 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 suciently 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
C 1.20
heating:
• Heater test:
Check the heating functionality
With
C 1.20
heating:
Measurement procedure
During a measurement, different phases are passed through.
These phases are described below
• Phase 1:
Filling the calorimeter with water
• Phase 2:
Filling the calorimeter with oxygen (Note: If the option-O
2
flushing under the main menu " Basic Settings is selec-
ted, the inner vessel is two times with Oxygen rinsed)
NOTE:
Alternatively, to display the graph may also have a detailed
view of be selected with the following information:
• Current temperature:
Mean value of the actual temperatures
• Ignition temperature:
the currently measured temperature
• Measurement time:
Display: duration of the measurement
• Fill time:
Filling the inner vessel with water.
The fill time is user specific and must be kept constant
on each measurement. Check the filter where long fill times
are used.
NOTE:
After switching on the calorimeter C 1 or after a break of 2
hours during the filling of the calorimeter C 1 is still carried
out an intermediate emptying (H
2
O - purge). Once the
water sensor detects water, the stirrer is switched on.
After a short waiting period begins phase 2.
