13:47 - What are the steps from starting MQ to get to this screen? I’ve gone different routes with the same response. The “gauges” displayed on _my_ screen shows TXV/Superheat on the left and CFM/Air Flow on the right. How can I get the PSIG suction and liquid to show from my connected Fieldpiece probes? I’ve tried Quick charge, start a new project, make a saved project active, as well as other things after opening the MQ app but with the same result. What is the required information that needs to be entered before I can see the pressures from the connected probes displayed. Am I missing a requirement? I have the following probes mapped: liquid pressure, suction pressure, liquid line temperature, suction line temperature, discharge line temperature, outdoor air temperature, return air temperature, supply air temperature, return static, and supply static as well as the iDVM550. The all the probe’s readings are accurately displayed in other parts of the app. For me to see the current pressures, I have to open the toolbox and go to the connected Fieldpiece probes list.
It'll be good for tech's to know the basis of the target superheat chart. From my knowledge, this is based on an approximation of the Tevap of 40F (TSH=Tiwb-(Tamb-Tiwb)/2-40) . Love to know Jim's thoughts on this.
E your back. We need to be concise with the youth of today. Not all techs understand that the vacuum is equalizing across the metering devise. When I add this information to my training sessions the lite bulb glows. We can’t leave out what we call common sense.
It’s the same chart for 410a. The refrigerant is different but the superheat calculation is the same. I noticed that also. I’ll reach out to HVAC School and see if they can update that.
Good to see you are doing well! So just to review, #1 We set the airflow to the condenser size or coil? Can you elaborate a little more on the part you said about what type of motor you have? Standard vs actual. PSC vs ECM? Thank you for such a wonderful app!
Set the airflow to the condenser size, with a PSC and look at actual airflow. With an ECM watch standard air flow. An ECM moves the same mass flow rate. A pSC moves the same volume with a variable mass flow rate.
Constant torque motors are set up similar to PSC motors however they have much less drop off in performance with higher statics. They also move a constant pretty constant mass flow like an ECM. The differences a constant torque motor is set by the wire taps and static and ECM is set by adjusting the dip switches to a preprogrammed SCFM.
Most cases coil is dirty, condenser is dirty, blower is dirty, secondary heat exchanger is dirty and then the customer has to pay a lot of money to charge the unit or search for a leak, might as well get a new unit.

Looking good, Jim!
always a pleasure in having you keep our heads in the game!
When you get a chance, run the same example for a Heat Pump?
Looking good young fella. Hope to see you back at Kalos in February!
Lord willing I will be there this year. In remission and feeling a lot better. Thanks!
Wow we need more
Jim, this was one of your best! Thanks again

Thank you, jim.. great to see you . Thank you for always sharing your great knowledge 🤟💯🌎
Thanks!
Nice to see you Jim!
Nice to be seen.

Thank God for mQ

Can a person buy the app or is it just for companies?
@@unabridgeddick6645 the app is a free app.
i wish more guys would watch your videos a lot of good knowledge and helpful to understand why we need to do things
Good video
Nice video interested on make of magnetic tablet mount
Hi, our system here uses R 410 refrigerant. The charging chart shows R22. I don't get that!
Good catch, it’s the exact same chart for 410a.
Glad to see you as it has been awhile!! As always thank you for a great and informative video!!
More to come!
SH chart for R-22, while system is 410-a?
It’s the same chart for 410a. The refrigerant is different but the superheat calculation is the same. I noticed that also. I’ll reach out to HVAC School and see if they can update that.
Good to see you are doing well!

@@measureQuick would it matter if it's constant airflow ECM or constant torque?
Constant torque motors are set up similar to PSC motors however they have much less drop off in performance with higher statics. They also move a constant pretty constant mass flow like an ECM. The differences a constant torque motor is set by the wire taps and static and ECM is set by adjusting the dip switches to a preprogrammed SCFM.
Thank you, Jim.👍👍👍👍👍👍👍👍👍👍👍.
Much appreciated Sir!
