How to Check the Charge in Superheat for Fixed Orifices! SMAN460 WB & DB

In this HVACR Training Video, I show how to use the SMAN460 Digital Gauge Set to Check the Refrigerant Charge on an R-22 System with a Piston Fixed Orifice. We use the Superheat Method and I show how to Manually Input the Indoor Wet Bulb and Outdoor Dry Bulb Temps as well as how to Wirelessly read the WB and DB in order for the SMAN to calculated Target Superheat.
I show correct charge and describe low charge and overcharged scenarios.
