Another super blindfold test. You came really close considering the low ambient. This also helps to show that just one ounce makes a pretty significant difference when the charge is close to target. Thanks for the demo.
same as a freezer we would add freon till we moved the frost line off the comp! or an ice mach evap! ac you just want a such line like a cool beer can!
I once worked for a company that forced me to charge a R410a split system with a fixed orifice when it was 50 Deg F. It can be done but there is a point when the low side pressure stops climbing when you are adding refrigerant and all you can really do is use your hand and assume you got the target superheat within range, Because if you have a low ambient indoors as well as outdoors your pressures will both read really low. Now if you had a TXV as a metering device well good luck with that one.

Straycurrent I am waiting for a low ambient condition to do another.

mechanicwarrior20 Had to deal with it! You never know if it is right. I will do some on low ambient to see how close I can make it.

Id like to see this on some different units!
