Do you need the Bluetooth vacuum gauge or can you just pull through the manifold, because when I tried pulling through the manifold I wouldn't get a reading at all

[@jodystrickland9150]

Did you ever get an answer?

He used a Bluetooth probe in this video. (552i)

@@Crookshanks117 when does the reading starts are gauges?

[@Justarandomspacemonkey]

I’ve tried using this option and left my vacuum running for hours and it never measured my microns

[@chinoguevara7411]

I tried doing the same and no reading can I not get reading just threw the manifold? Do I need to get a Bluetooth vacuum gauge?

The graph on my 557s does not ever move when evacuation. It says it will start when 7500 micros are reached and I'm well below this. It was working before an update.it only works when I hit start

Wondering how is one suppose to know the pressure test can only be doing using the high side? Manual states nothing about only using the high side on the pressure test. That should really be included in the manual. Couldn't get the micron/vaccum gauge to work either...I guess I shoulda got a Fieldpiece....

Sir i have Testo 557s but evacuation time i reach 200 micron but then i try to start leakage test its will go high and high i get your hose also can you provide best quality hose for vacuum

Where is the sensor? 😂

I thought the same thing. But then I did realize if you put a ball valve at charging port on the gauges and close it and close the suction valve too you should be good. They should have a valve for that charging port like on the 557s
