testo Smart Probes

I got my 770-3 multimeter about a month ago and liked that I could use the app to record and screenshot readings for my work. But now the temperature readings on the screen I can’t change to Fahrenheit, it always goes back to Celsius. Please fix this and why not allow the app to remember my choice of what I want to view verses having to change it every time I have to start the app.

So I have to say the probes and devices are great. Read accurately, however the app is horrible. If you rearrange the view or make any items not visible it will permanently place a sensor measurement called NONE in the measurement arrangement list. It NEVER keeps your arrangements. I have two smart probes temp sensors so I can take readings from the return and the supply at the same time. I want the Both DB readings to appear at the top followed by the WB readings, then RH. I don’t need any of the other settings. So I rearrange them to do this and set the other ones to not visible. Works great, this time. Next time I open the app, it is all disorganized again and a whole bunch of NONE listings are in the rearrange list. It is frustrating to no end. I have reached out to their tech support through email but have got no response. If they fix this I will adjust my review.

I have used the App and Refrigerant Probe Set for a few weeks. Most of the app is easy to use but you must maneuver through all of the screens to understand what is possible. The Probe set is extremely handy due to compact size. I carry in my backpack along with one hose in case more refrigerant tasks are needed. I also added service fitting tee with No-Loss fitting to my pressure probes. No frostbite. Recommendations: 1. That the Application Selection menu have a custom version. 2. Fix the AC & Refrigeration application because the Evap and Cond Saturation Temperatures will only show in degrees Celsius. I set Fahrenheit and PSI but can’t change the other two. 3. Permit ability to add two more sensors while using AC & Refrigeration so that other temperatures can be measured. More ideas may come your way as I use it more. Keep it up Testo team. Thanks Tony

I use my set everyday for service work. I set mine up on my yellow jacket manifold with a ball valve between the manifold and the testo i549. I love it makes it a breeze. Also allows you to keep track of super heat and sub cooling every second. Also shows you psi vs temp and coil temps and superheat and sub cooling. #MONEYWELLSPENT THX TESTO FOR MAKING MY JOB EASIER. I HAVE MINE SET UP ON A OLD SMART PHONE BECAUSE IT KILLS MY IPHONE BATTERY.

They’re app is good, gives accurate data, has up to date refrigerant list, and finally target superheat. They need to update the app to read microns off of their micron gauge, it currently only read in mercury and does not give the option for microns. Also, it’d be nice to be able to have a timed decay test feature for the 552. Another feature that would be nice would be having a designated 770-3 tab for testing electrical
