Just recently started doing comercial (job forces move) and got myself booked on a coures but that starts September.
Now i would like to start using pt charts now as i can see them being very usefull.
I have downloaded one for the 134a gas (the only one i use) but i cant find any thing on where to take the temp evap, condensor, dryer ect, and does it relate to the high or low side. Any help would be great.
