I use NCD PR52-33N to monitor the vibration of our equipment, and through Node-red build a dashboard to monitor and export vibration data.
However, the data I collect is weird, the vibration value is so big and oscillating very serious, the collected data I think is not reasonable. I use another vibration instrument(EXTECH SDL800), the collected vibration data are stable and the value smaller than the NDC sensor collected. Do you have any idea how to correct this problem? I reset the NCD sensor on a stable desk to make it self-calibrate, but the result still the same.
Below is the data I collect from both sensors, I collect the vibration data on three different machines.

Thank you so much!
