New helium log
Enter manual trailer readings; derived fields update instantly and are stored when you save.
Copy readings from the most recent log as a starting point.
Manage list on Trailers. Fields stay editable.
Auto-filled from the selected trailer. Update trailer/site mapping under Trailers.
For this site, the dashboard lbs/day window ignores every log strictly before this log's date. If several logs use this, the latest such date wins; it also competes with the latest Inflation (whichever is later). Inventory, Inflation, and Purge are still excluded from the lift total itself.
On new entries this comes from the trailer registry (quick fill above), or from "Duplicate previous entry"—not typed manually. Add trailers under Trailers.
