Rectification : Root Mean Square (RMS)
Peak-to-Peak (p-p)
Peak-to-Peak (p-p) rectification for low speed
Note)
・ Rectification is calculation method to convert vibration waveform to amplitude which may
be different from monitor range scale.
（Ex. p-p conversion scale by RMS rectification）
・ Refer to Table1 for rectification selection.
・ The peak rectification is recommended when high speed response time and true p-p
rectification are preferred.  The RMS rectification is recommended when noise
resistance or runout inhibition are preferred.
