A brief Description of each Calculation Method
rms: “rms” is “Root Mean Square”. This is the square root of the mean of the squares
of the time-series data gathered from measurement. ISO standard sets RMS as
evaluation criteria of the vibration velocity, which is also known as vibration
severity.
EQP: EQP is a value gained by “rms”×
√
2
. This formula is suitable to use for
measurement of sine vibration generated by rotational machines, for example.
Peak: The maximum value of the time-series data.
For detailed explanation, refer to the definitions in Section 10.
