RMS Data Calculation Process

Hi, I’m looking for the process how the rms data is being calculated in vibration sensor. Is that any documents that I can take a look?
I’m guessing the vibration sensor is measuring the peak data, and mutiplied by 1/sqrt(2) is that right?
The sensor is about wireless vibration temperature sensor V2 and V3 as well.Thank you!
All the answers will help me a lot. Thank you!

I found the solution. Need to delete
