lower address. Knowing the starting time point (Mission Time Stamp) and the interval between temperature
measurements one can reconstruct the time and date of each measurement.
There are two alternatives to the way the DS2422 behaves after the datalog memory is filled with data. The user
can program the device to either stop any further recording (disable “rollover”) or overwrite the previously recorded
data (enable “rollover”), one entry at a time, starting again at the beginning of the respective memory section. The
contents of the Mission Samples Counter in conjunction with the sample rate and the Mission Time Stamp will then
allow reconstructing the time points of all values stored in the datalog memory. This gives the exact history over
time for the most recent measurements taken. Earlier measurements cannot be reconstructed.
