Hi All
Note the value highlighted in the attachment, this has had me intrigued for a while as it doesn't relate to anything in my associated trends or spectrum, not that I can see anyway.
Thanks in advance for any enlightenment offered

I assume Peak = 0.217 is based on Sine wave (pseudo peak), so 0.707 x .217 = 0.153 for RMS Value
Peak(+) value would be RMS x Crest Factor or 0.153 x 7.671 = 1.177 or pretty close to 1.179

Emerson-CSI typically includes the Peak (-) value from the waveform as well. I believe they typically recommend Trending the Peak-to-Peak value that is a Parameter Set selection.

Thanks Walt, another mystery (to me) solved.
