Average
Calculates the average value of the waveform data.

P-P
Calculates the value between the
maximum value and the minimum value
(peak-to-peak value).
Maximum value
P-P
value
Minimum value
Maximum
Calculates the maximum value of the
waveform data.
Maximum value
Minimum
Calculates the minimum value of the
waveform data.
Minimum value
Time to max
Calculates how long (s) it took for the
waveform to reach the maximum value
from the start of recording.*
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.

value
Time to min
Calculates how long (s) it took for the
waveform to reach the minimum value
from the start of recording.*
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.
