Logging Summary
The time the first data point is recorded at.
The time the last data point was recorded at or recording was manually stopped at.
Total recording duration time, which is calculated from the first point to the last point.
MKT (Mean Kinetic Temperature) is a simplified way of expressing the overall effect of temperature fluctuations during storage or transit of

E = activation energy (
standard value: 83.144 kJ/mol
)
R = 8.314472 J/mol (universal gas constant)
T = temperature in degrees K
n = the number of sample periods over which data is collected
Note: ln is the natural log and ex is the natural log base.
