NOTE: Based on both the memory size and on the log interval, the form provides an estimate of the date
when the memory will be full. At that time the data logger will stop recording data. The estimated date does
not take into account the remaining battery lifetime or the effect of the log interval value on the battery
power.

7.2 Adding a calculated parameter to the log file
HW4 View Data can be used to add a calculated parameter such as dew point to a log file comprised of
relative humidity and temperature records. The parameter is calculated for each data record based on the
relative humidity and temperature values.
HW4 View Data can also be used to replace the calculated parameter in a log file with a different one.
