For an absolute CPC 6000, this automatic function will:
1.
Vent the system.
2.
Select the turndown with the smallest span that can measure the vented pressure, or read the inter-
nal barometric reference if installed.
3.
Record that pressure as “current barometric pressure”.
4.
Adjust the zero offset of each turndown so the turndown’s output equals the “current barometric
pressure”.
