Indirect leak check

The 23-point sheet · fields compute as you go

The numbers match the rig diagram — put each reading down where you took it and the derived fields work themselves out. Leave anything you didn't take blank.

Refrigerant — turns the gauges into saturation temperatures

Evaporating— °Cfrom gauge 13

Condensing— °Cfrom gauge 5

Total SH— Kpoint 21

Subcooling— K5 vs 6
