Is the pressure supposed to be negative? In a vacuum? Are you sure those gauges are working? It appears you were even surprised by the readings since you said the charge was weighed in. And hot inside the garage would make the pressures go UP, right?
I lost some refrigerant when I was putting on the guages off camera. I discovers it after I had uploaded the video that it stoped cooling. So yes the were correct. I had to come back the next day to fix what I did. Lucky it was my refrigerator so no upset customer lol.
Can you use the gauges without having to use all the App B.S? When you have multiple service calls a day, I don’t have time to do everything with my phone.
This gauge has just a 1psi sensitivity/resolution vs 0.1psi for high end models (like Testo, etc'). Is 1psi sensitivity enough if I want to make leak testing of the system?
I noticed you hooked your line with out bleed the air out and now you just put a lot of air in your low side unit should of been off bleed the line then turn back on

@@appliancerepair420 what is the low side pressure supposed to be? Certainly over zero, correct?
@@realSamAndrew 0-5 psi but ambiente tempreture affect it.
@@realSamAndrew R134A typically inside climate controlled buildings around 15 to 18 psig on cap tube. Will be higher inside hot space
@@Texastreasure1984 15 to 18 psig is a far cry from negative. IE vacuum.
Does this measure the temperature of the refrigerant or is that temp displayed just the sat Temps?

You can. I just like it on the phone.

Do the updates cost anything
Dear, which updates are you talking about?
I don’t think so.
@@JuliaLima-Elitech If i buy chinese dmg-4b, can i update with 454b refridgerant?
Como puedo descargar la función de vacio y presurizado gracias
Deja veo si consigo la información. Yo le aviso.
Estimado, pudo descargar las demás funciones del aparato? Gracias
Can it be used to recover the refrigerant?
You can use it like any other guages.
