Question Tutorial - Checklist Confusing when presenting Yellow parts

Tutorial - Checklist Confusing when presenting Yellow parts to record as I can't see where its refering to record from? anyone able to point me towards a Good tutorial. I'm always able to get into intial orbit its always in the prep up to Luna Transfer that I get stuck as it asks me for info I don't know where to find or its telling me in the check list to record numbers but doesn't seem to suggest where I can find these numbers for temps and Psi Etc. the Dials I've found with PSI and Temps don't seem to be clear. Sorry if this is a noobish question I just sadly want to learn this but rarely get the chance to read the full 1000s of page documents so looking for a clear cut video that I'll find easier to follow

Yellow text in the checklist can mean either:
1) The system is not implemented
2) It must be done manually
3) It's for information

For things like 'record O2 quantity' or 'record Main A voltage', I usually just ignore them. Those were part of the original checklists where they had to make a report on the performance of the spacecraft systems as the flight progressed.
