*: Calculates the time from the trigger point when the trigger is used.
Only one threshold value can be set for each channel. If you specify the same channel for the ON and OFF
time, the same threshold value will be used.

Calculates the average value.
Calculates the difference between the minimum and maximum values (the peak-to-
peak value).
Calculates the maximum value.
Calculates the minimum value.
Calculates the time from the start of recording until the maximum value.*
Calculates the time from the start of recording until the minimum value.*
Calculates the integrated value.
Calculates the integral value.
Calculates the rate at which the measured value is greater than the threshold value.
Calculates the total time for which the measured value is greater than the threshold
value.
Calculates the total time for which the measured value is less than the threshold value.
Calculates the number of times the measured value crosses the threshold value in the
rising direction.
Calculates the number of times the measured value crosses the threshold value in the
falling direction.

Calculation results will be saved at the specified interval
starting at the reference time.
The initial interval after the start of measurement will be
automatically adjusted so that results are saved at the
segment time as measured from the reference time.
