If I use the Dump function to transfer data to the SD card, does that clear my history from the internal memory or does it just copy it to the SD card? I don\'t want to clear it.

You can find the data download settings on the parameter/equipment page of the paperless recorder. These settings can be configured to either "Dump and Clear" or "Transfer and Remain." This setting will affect how you download data to an SD card, USB drive, or computer via the Historical Viewer.

If you choose "Transfer and Remain" the paperless recorder will make a copy of the data on the SD card/USB drive and retain the data on the PR (paperless recorder).
