displayed are: Minimum value, maximum value, average value (mean) and standard deviation.
For temperature channels Mean Kinetic Temperature (MKT) is displayed as well. MKT is used in pharmaceutical
and food industries as a simplified way of expressing the overall effects of temperature fluctuation during storage
and transit of perishable goods. The software uses the activation energy value H = 83.144 KJ/mol for MKT
calculation.
The data statistics are also included when data is exported to a text or Excel file.
A typical Data Summary window is shown below.
Using the Data Filter
The data filter helps to display only relevant information in the data listing window. It can also decrease the number
of printed pages when the data listing is printed. The data filter allows you to:
• Hide sample points when the data did not change sufficiently.
• Show only data points that were sampled in a specified time period.
