- Learn how the mini split workflow works in measureQuick. Find out what probes you need, what you need to measure and where to measure.
Also, we use the Mass Save workflow as an example, so if you're a part of that program you can use this video as a learning tool.
Tools used in the video
AccuTools 5/16th core depressor

That’s awesome! I’ve been waiting for this. It would be great if you could do a video on utilizing measure quick with package units.
Thank you for this video. I have to start a mini split,but in the heating mode. I will check the options fir that particular case tomorrow.
9:37 - An excellent workflow for me to access (straight out of refrigeration school and thrown into working on a number of walk-in coolers) would be a refrigeration workflow that involves a rapid cycle hot gas valve for maintaining temperature at close tolerances. Also helpful would be one for an RTU package system, specifically at least describing air flow probe placements and where to put the Sauermann probe on the RTU for combustion gas analysis. Each of these RTUs has gas heat, so steps for clocking a meter that feeds several units at once would be good. Most of the workflows I see in MQ are for residential equipment. The cold rooms I’m working on, as I said have close tolerances and none of the refrigeration profiles in MQ are 36 degrees @50% RH. I only see a walk-in freezer in there. Thanks for all you do, Jim
Good stuff!
Can you please do a full class on the fieldpiece 680 meter with mQ
Hi,
I would like to see more for Mini Split, we have here in Bosnia a lot of Mini split which use Capilary tube, so testing and charging process will be useful for us, I am one of rare who is useing Testo and your app😁
Lol love the bloopers at the end
I knew this would eventually come around thanks for providing.
Since many of the more well-known companies have hardwired a test mode into their units that the actual manufacture use to set their condenser fan to a specific CFM flow they said their air handler fan to a specific flow they meet her there electronica expansion valve.
Are using all the manufactures specifically placed temperature sensors and pressure sensors to determine proper operation i.e. superheat and sub cooling.
Could measureQuick better refer to the technician to RTFM and measureQuick software incorporate this information to better take measurements ?
Yeah mini splits are a real pain to test because they are so manufacture specific. This workflow is more to assure everything is in the ballpark of acceptable and allow you to benchmark the system. I was working on it for over a year before I get something that would be of some value.
👍
Sweet!! Is there anything that Jim can’t do?
I have LG and Mitsubishi systems with there air handlers do i test them as conventional or ductless. also have some with multi air handler and wall units how would it use MQ for them. thanks
So if we have a three head unit, we would need to have six probes to maximize this feature. Or can we do it with one set? Thanks again Jim for continuing to improve MQ
Yes, you could do that. Up to 4 supply and 4 return probes.
On these mini split when we install long runs we remove the metering device and install it closer to the evaporator.
Great video Jim. I have a few questions re mini split diagnostic. Can you do test in a heating mode as well?I live in New Zealand and we use SI system, so i'm confused with use of Fahrenheit temp, BTU or Tonnage,SEAR etc. Is any chance that you do some changes in a app for the international use? Thanks
MQ does heating as well and it does have SI units available.
@@measureQuick Thank you for your prompt reply. Actually I tried to do diagnostic of Panasonic R32 3.5 kW output mini split in heating mode but i couldn’t find that option in MQ. There is just cooling option for mini split. Also some system inputs are not possible to enter consequently shown unstable system. Thanks.
Can this be used on multi zone systems and also on geothermal unit
Thanks Jim, I have a question how can we measure air flow in mini split A/c? Can we use large vane annometer?
There is no good way to do it accurately. I usually use the manual input and use manufacturer rated. If the blower is clean that should work well.
You could, I have done that before.
What's the range on the return and supply probes to the iPad?
They are rated at 1000’, but reasonably 300-400’ through building materials.
I have the app and I absolutely love it but why when you go into the trending graph, superheat is red and subcool is blue????
So we got a little technical with that. Superheat is heat above saturation and subcooling below saturation. I get what you are thinking, low and high side of the system. At some point we are going to make that whole section a lot more user configurable. It has just been a lower priority.
@@measureQuick oh ok. It’s nothing big, just a little nit pick. Absolutely love this app though. I’d donate money to you guys for working so hard if I could lol
How does this work with multi head units?
Start all of the heads, you can use multiple supply and return probes if you want and it would average the readings.
@@measureQuick Can you just pick one head unit to test on a multi head unit
We were all hoping Jim put his phone number so we could screen shot it.
