If LET values are not higher than 4 when measuring sediments, this means that the contact between probe and sample is insufficient." If the highest LET value of the iterative measurements is 4 and over, the data is evaluated as "Qualified" and low quality measurement results (LET <4) are excluded from the average of thermal conductivity. In case the highest LET value of the iterative measurements is lower than 4, the data is evaluated as "Unqualified" and the average of all measurements is given as the thermal conductivity.
