The statistics available are:
•
Number of Readings
•
Mean
•
Standard Deviation
•
Coefficient of Variation
•
Highest Reading
•
Lowest Reading
•
% greater to or equal to NDFT
•
% between 90% and 100% of NDFT
•
90/10 pass or fail
e.
The temperature of the surface used for calibration
should be equal to the temperature of the substrate
