How to recalibrate the heat capacity of calorimeter?
Please re-calibrate the Heat Capacity as follows:
1. Select the mode to Heat Capacity determination
Select “Heat Capacity” in [setting] - [system setting] - [analysis content], input “Bomb No.” and Calorific Value of “Benzoic Acid”, then click “OK” to save it.
2. Do 3 trail tests of Benzoic acid
(1) Do 5 tests of Benzoic acid to get calorific value
If the value (the maximum value subtracts the minimum value) ≤40J, you can calculate the Heat Capacity: Enter [functions] - [Calculate Average Heat Capacity], select the 5 tests’ results, select “recalculate” and “save heat capacity”.
(2) If the value (the maximum value subtracts the minimum value)>40J, please do one more test.
a. In the 6 tests’ results, select 5 tests’ results which can reach requirement of value (the maximum value subtracts the minimum value≤40J). Then use the 5 results to calculate Heat Capacity: Enter [functions] - [Calculate Average Heat Capacity], select the 5 tests’ results, select “recalculate” and “save heat capacity”.
b. In the 6 tests’ results, if any 5 results cannot reach requirement of value (the maximum value subtracts the minimum value) ≤40J, please redo 5 tests again.
(3) Enter [system setting] - [setting] first and select the mode to calorific value determination. Then you can test the standard sample and compare the result with standard value.
