Numerical calculation formulas

The following table provides a detailed description of each numerical calculation.
Calculation
type
Calculates the average value of the waveform data.
������������ =
Average
Calculates the value between the
maximum value and the minimum value
P-P
(peak-to-peak value).
Calculates the maximum value of the
waveform data.
Maximum
Calculates the minimum value of the
waveform data.
Minimum
Calculates how long (s) it took for the
waveform to reach the maximum value
from the start of recording.*
Time to max If the maximum value occurs at 2 or more
points, the first time the waveform targeted
by the calculation reaches the maximum
value is used to determine this value.
Calculates how long (s) it took for the
waveform to reach the minimum value
from the start of recording.*
Time to min
If the minimum value occurs at 2 or more
points, the first time the waveform targeted
by the calculation reaches the minimum
value is used to determine this value.
Calculates the integrated value for the measurement data.
Aggregation
(Total)
SUM =
Calculates the integrated value for positive measurement data.
Aggregation
(Positive)
SUM =
Calculates the integrated value for negative measurement data.
Aggregation
(Negative)
SUM =
Calculates the integrated value for the absolute value of measurement data.
Aggregation
(ABS)
SUM =
*: Calculates the time from the trigger point when the trigger is used.
