Hi, I am working a process in HVAC system, monitoring discharge and suction pressure on a chiller.
The sample time is about 15 minutes (or 900 seconds), hence, the csv file fail to upload.
The pressure signal cycle is about one day.
In order to test, I am scaling the timestamp on 1/1000.
After results, how can I scale again in order to have the correct WA or Arduino library?
