3.
Enter the sample MASS (weight of sample) by selecting F1, ENTER, Type mass (e.g.: 0.5432) and ENTER.
4.
Place the vessel in to the filling station and fill it with oxygen. Then place it in the CAL3K-A well.
5.
Close the lid until you hear a click. You may have to press the lid down.
6.
The CAL3K-A checks everything out and issue a warning if something is missing.
7.
The CAL3K-A will then go into an INITIAL waiting period. The time is indicated in the top line on the LCD
screen.
8.
After 2 to 3 minutes the sample is fired. This is displayed and announced with a short beep. You will notice
on the top line of the display the FIN period
9.
After 2-3 minutes the result is displayed in the bottom line of the display and the lid opens.
10.
Put the (warm) vessel in to the cooler. You will hear the fan coming on, and after a while (time is indicated)
the cooler fan will stop and the message “VESSEL READY” is displayed. The cooling time depends on the
Room temperature and vessel temperature and is indicated.
The above is just a short step-by-step procedure to run your first CV sample to make sure your calorimeter is in
working order.
There are many additional steps and procedures that you can do whilst running an actual CV sample. You will find
these How to Steps via the On-line Help Guide available on the website:

CALIBRATION
All vessels are calibrated in the factory with the calorimeter before shipment. Note that the calibration is saved for a
particular CAL3K-A chassis and for a particular vessel number. If this pre-calibration is not possible then the full
calibration procedure must be performed in the field. Here follows a SHORT description of the various calibration
procedures:
CALIBRATION
As above, but it affects the bomb factor with the average of old and new bomb factors. This is also entered in the
calibration history. Perform this once a day/week.
INTELCAL CALIBRATION
This requires a PC. The PC reads all the saved history calibrations and performs a SYSTEM calibration with the data. It
requires 7 to 10 history entries and when done it will download the IntelCal calibration data to the vessel. Perform
this once every 1 to 6 month. The unit is shipped with a universal default IntelCal calibration set.
VESSEL CALIBRATION WITH MORE THAN ONE CALORIMETER
If you have more than one calorimeter and you like to operate every vessel in every calorimeter then you must
calibrate each vessel in every calorimeter. A maximum of seven calorimeters are allowed per vessel.
