Operate, step 8 of 8

It was fine yesterday. What changed?

A machine in service fails in a small number of ways, and each one has a spectrum. This step reads the failure mode from the residual gas rather than from the pressure alone.

Reading the machine you laid.

What already answers this

Nothing below is a copy. Each line is the surface of this site that carries the answer, and what it carries.

What the pump corpus can tell you about the machine you run

333 validated models across 14 families, 3830 parameters, each one carrying the source key and the page it was read on. Every family below is a family this site can name a model in.

A machine that drifts is read from its residual gas first, and from what its pump is rated to do second. This step carries the second. The block below carries what the corpus knows about how the pump you laid actually fails.

What this step cannot answer, and why. Every count below is read from the corpus at build, so this block shrinks on its own the day the data grows.
