Just so I organise myself for the job,

How do I read/get measurements for the following:

Saturated condensing temperature
Do I read this off my pressure guage hooked up at the receiver end?

Saturated evaporating tem
Again, I presume I read this off my gauges pressure/temp chart


COOLING MEDIUM SUPPLY TEMP

I presume thats evaporator fans, supply temp is the temp of air entering the evaporator, or is it leaving the coil?


I think I understand the rest
Thanks in advance
