The duration of each element in a measurement is called Profile Time. This time can be selected
in Hours, Minutes, Seconds and Milliseconds. The longest selectable period is 23 hours, 59 minutes and 59 seconds
The shortest time (highest resolution) is 5 milliseconds.
Short profile times increases the workload in the instrument, and also requires more storage space. For very short Profile Times,
(5 ms) the instrument cannot perform recording, and may record one frequency dependent function. For Profile Times between
5 and 25 ms, 3 frequency dependent functions is maximum. Above 25 ms, all combinations are allowed.
If Profile time is less than one second generation of text reports will be switched off.
