question, when you did superheat in analog your SH was 8 and SubC was 8 with your meter it SH was @ 16 and SubC was @ 8 is the meter off? of did u mis calculate?
Sorry I'm new at this and my questions may seem redundant... So superheat and subcooling range is just the difference between saturation temp and outside line temp? Is the range required for superheat and subcooling always going to be 9-12 degrees temp difference between saturation temp and outside line temp? When charging a system is the idea to try to get the saturation temp and outside line temp to be within 9-12 degrees of each other?
Testo offer two versions of the testo 550, a basic kit of meter and a clamp probe for $299 MSRP and a Deluxe Kit with meter, two clamp probes, and a carrying case for $399 MSRP. Contact your local wholesaler or favorite internet reseller, as they have these on sale. Testo is running a $75 mail-in rebate when you purchase the new t552 Digital Vacuum Gauge and any one of the Testo manifolds.
Hey Sir, just a question, please. What about weather? Does it affect superheat calculation? Is it important to regard indoor temperatura before calculating superheat? Should superheat be calculated on sunny day or it's better on winter day? What would you recommemd me? Thanks a lot.
Superheat calculation is what is happening in the system. The target superheat calcuation is impacted by the weather. In the May 2006 issue of Contracting Business the article, Superheat: The Best Way to Tune an Air Conditioning System provides a good explanation of these. I tried to post the link, but I'm getting an error.
Can you scan that Calculation Sheet and upload on your website for download. I do ref. charges daily and could use a tool like this. Please look into it.
I did a Google search for "hvac job site calculation sheet pdf" and I found the form you can use. I tried to post the site here and youtube would not let me - I hope this helps
as well but if the superheater is correct or not should make a chart that indicates the superheater is correct. because they do not save if you need more refrigerant charge or remove refrigerant charge.

FYI there is a temperature pressure chart on your gages.

Hey testo guy I liked the video you put out! I was curious if there is a way to get access to the work sheet you have?
what didital gauges where you susing to find subcooling?

What sheets do you use? I really would like a copy of those.

Why was superheat and subcooling different for the analog and digital measurements
Was this the same unit
😁😁😁
Thanks sir

May I have a pdf for those service sheets you write on? They will help me in school greatly :)
Testo 905-T2: The instrument used for sensible heat measurements
I'm fairly certain the model # is 905
How do you get the manufacture literature.
Chris H, you can go to www.testo.com/product/0563+1550/testo-550-Digital-manifold-kit and click the green request more info button.
compress ration is 3.5 to1
You don't need a chart. Those temperatures are right on your gauges.
Look on your gauges, they are already on there.
Don't guess! Calculate...
low side pressure is to high
+hatprick i think that too... but maybe is normal for 410A
