Historical Compression

Just a quick question about the compression - it wasn’t super clear in the manual, but if I use an analog mode and then use the percent deadband method - what is that a percentage of?

The range of my tag defined in metadata?
The range specified in Numeric?

Just curious - don’t think I am setting them up right because I am getting more records than I like.


It’s the percentage change between the engineering limits defined on the tag
