6 - MAIN CAUSES OF POOR RESULTS
Since the function of the appliance is to process a sample, the cause of poor results may
not be attributable to the appliance.
Poor manipulation of samples (with absorption of humidity at the end of the test),
inaccurate weighing, an error in entering the weight, an error in identifying the samples
may all cause errors in the expression of results.
In the case of a doubtful result, it is appropriate to:

Check the condition of the cover after the test. If leaks have occurred at that
location there will be traces on the cover. Also, check there are no deposits on
the oven mouth and the oven cover that could adversely affect oven
Air tightness.

Check that the exhaust of the oven is not partially or completely blocked.

Check that the gas system is properly open and that the flow rates are correct.

Ensure that the load placed in the vials is not excessive and that there has been
no loss by overflowing.

Finally, check calibration of the oven thermo-couple.
