Each vessel can have 16 calibrations per mode.
Each calibration contains Bomb factor, Environmental conditions, Drift, Stability and more data.
The objective of the calibration management is restricting the number of entries, grade them, block the bad ones and avoid overflow.
This is performed automatically without any operator intervention.
The process starts when 4 calibrations are saved and continues from then on with every new calibration.
Each calibration is analysed and compared to all other calibrations. If a calibration is not acceptable, it is flagged for blocking.
If sample determination is performed then the best calibration average is used. This could be any amount but more than four.
Once 4 calibrations are saved, the calorimeter performs a calibration assessment and computes the heat loss, environmental and equipment characteristics. This is a ‘sort off’ selecting and grading of the best calibration data. This operation is performed at every following calibration.
If more than 15 calibrations are accumulated then previous blocked ones are overwritten. If no blocked calibrations are found, the oldest one is overwritten.
The number of vessels per calorimeter differs per unit and is restricted.
START A CALIBRATION
The calibration of the CAL3K is a process in which a substance (Benzoic Acid, BA) of known calorific value is burned so that future burning of unknown substances can be compared to it. In other words the calibration records all the system variables such as temperature rise and heat loss in memory. All this data is called a calibration field. The calibrations are stored in the vessel.Learn More
PERFORMING A CALIBRATION
To perform a standard calibration using Benzoic Acid Tablets you will need : A working oxygen bomb calorimeter system connected to a power source, A CAL3K Manual Oxygen Filing Station connected to an oxygen supply (not needed when using the CAL3K-AP Calorimeter)...Learn More
INTELCAL SYSTEM CALIBRATION
The CAL3K system uses two calibrations: Keyboard calibration, in real time, one sample, average with last ‘n’ calibrations, PC calibration, in retrospect, multiple samples. The PC calibration is called ‘IntelCal’ because of its complexity and system effectiveness.Learn More
