Review on Yellow Jacket 46062 - Digital Series 41 Series Manifold with 3 Inch by Joe Lara

I used them on my 134a system. Note that these sensors will turn off after 10 minutes and you will have to return to your current location (this will not be saved). You cannot disable this feature! I called the yellow jacket and they are programmed to save battery (right)! It's a great tool, but this feature is absurd when it takes 10 to 15 minutes for the air conditioner to get up to operating temperature and then the sensors turn off one by one. At least there is an option to turn it off during system recovery or diagnostics. If they fix this feature it's a home run and I'll buy again but now they're coming back.
