    Just hooked up my digi's and it did the work for me never really looked at a PT chart with vapor/liquid pressures.

    makes me think back a few years ago, back to a chain of stores my old company used to service.

    Each case used a case controller that used a pulsing metering device that based superheat off of coil inlet/outlet temperature difference.

    Each store was R-404A and worked well.

    Then they put in a 407C store...and it was oil fail central.

    This actually proves a point I tried to make a few times and got slammed for it.... Glad you knew the manifold set was smarter than you were....

    Not being condescending, just appreciating you know the difference.

    If a day goes by and you have learned nothing, I hope you got a lot of sleep.

    Cooper 4011 fits great on the little tubes well as suction lines or return bends.
    Much easier/better than the beaded K-Type IMO

    Phase Loss This might help it sink in. This was on a unit overfeeding. In the pic it shows bubble, dew for the pressure and suction temp.
    It's easier for me to grasp glide when seen this way vs pt charts and graphs but maybe somebody has a better way of explaining glide. HTH

    Try the fluke 80pk-3a touch probe. I have several of the fluke temp clamps, but like the touch probe best.
