I replaced a leaky filter drier. Weighed in and took my gauge reading and subcool. But my delta t was only 5 degrees. Threw me off. It was 90degrees inside. Had my supply probe on the outside of the vent and the hot air was twirling back and mixing with the cold air. Great point that you mentioned. Put it inside. Can't stress it enough
Thank you for the video and for MQ. I just want to confirm. Testo and Fieldpiece probes can be combined when taking measurement? I thought that was not possible. I have a Fieldpiece Psychrometer and Testo probes. I was going to get rid of the Fieldpiece Psychrometer.

hi there i got a question about measure quick app, does it guide you or tell you charge statis , like add refrigerant or remove , depending on piston and txv ( subcooling /super heat). id like to try using your measure quick . i have been using supercool app or check and charge app up to now to guide me thru charging statis at end of day after setting up my airflow .
Where do i put temp probe in a commercial hp with accumulator before or after accumulator?. Shouls I put it before dryer or after dryer? Thank you Jason
I’ve noticed on Measure quick it will give me an approximate CFM per ton. What information is that using to determine that because I have found it to be wildly inaccurate compared to manufactures specs with static pressure
If you had your iConnect or IManifold on. The probes are Zigbee, so they need to talk to the base unit. The easiest solution and the best solution would be a couple of Testo 510i manometers. Those will also work for gas pressure. The iManifold manometers will not.
james ryan Depends on if you’re measuring total superheat or evaporator superheat. Most of the time I measuring evaporator superheat only when I’m setting the valve. After that I measure total superheat to make sure of two things, one the superheat is not too low going into the compressor, two, the suction line temperature is not too warm.

Great explanation Jim, thank you.
You are welcome!
Ive been doing the supply air probe too close to the air handler for a long time. Thanks ill change that .
Thank you for teaching me
I’m in school, RCC community college in Riverside, California

That is correct. You could use 4 different brands at once if you wanted.

So for the liquid line temperature, you're putting your temperature clamp about 5 to 6 in away from the compressor?
That would be the discharge line, 6-10”. The liquid line is near the service valve.

Jim has 3 temperature probes, is it possible to only use 2 temperature probes on a heat pump or will three be a more exact measurement of the system?
Hello can we mix match probes in measure quick like fieldpiece and testo?
Yes you can
So I could use my IManifold Manometers in conjunction with my FP JobLink set?

shouldn't superheat probe be as close to indoor coil as possible?
