STEP BY STEP ENTERING THE SPIKE MASS
- Place the crucible on the Balance.
- Press “Tare” to clear the weight of the crucible and get to 0.0000g
- Place one Benzoic Acid tablet (as a spike) and note the Mass = Spike Mass
- Enter the Spike mass by ‘Spike Mass’ enter, mass value
- Tare the balance
- Add the sample to the crucible and note the sample mass
- Enter the sample mass electronically (F5) or manual (F1)
- Place the prepared crucible (benzoic acid tablet with sample) in the lid assembly, inside the Vessel, close the Vessel and insert it in to the well.
- When using MANUAL FILLING, fill the vessel with oxygen BEFORE inserting it into the well.
- Enter the SID, e.g. 001
- Close the Lid of the Calorimeter
- The CAL3K Calorimeter will now perform some standard checks and if all is okay, it will begin with the “Initial Phase”, “Fire”, “Main” phase and then indicate that the determination has been completed.
Once the determination is complete, the result will display the calculated calorific value of the sample. The calorimeter will automatically take the end result, minus the spike energy and present the final result of your sample.

A ‘SPIKE MASS’ greater than zero indicates that the sample was spiked. The spike mass is set to zero after CV determination.
The ‘SPIKE VALUE’ is set to 26.454MJ as a default. It can be changed from the keyboard after the password is entered, by:
