Crasht ständig und verliert Verbindung

Grundsätzlich ist es ja toll eine App zu haben, aber ehrlich: Die App crasht am kaufenden Band, verliert ständig die Verbindung zur Hardware. Der einzige Vorteil für mich, ist das unkomplizierte umschalten der Messwerte, man muss nicht durch alles durchklicken. Wenn die Abbrüche und Crashes nicht wären, durchaus brauchbar, aber generell überflüssig

App zur Hardware

Grundsätzlich funktionell und gut, wenn man die passende Hardware hat, aber Aufzeichnungen lassen sich nicht komplett speichern. Zusätzliche Angaben (wie Memo) werden nicht gespeichert. Zudem werden Messungen mehrfach gespeichert.

Company Replaced PC-Z multiparameter tester

Apera replaced our defective PC-Z multiparameter tester. The app now fully connects via bluetooth to the PC-Z multiparameter tester.

First it looks good, then you realize how bad it is

I would like to start with the bugs. I've created about 15 categories, then made around 100 tests and saved them in those categories. Today, guess what? All the categories are lost or missing. Not a single one of them was saved!!! It ruined my work!

Then, the usability. There is no way you could make all 5 tests at once and save one single file. Oh no, you need to make 5 different tests and save them separately.

After that, some options have not a even a single description to them. For example, the TDS compensation. You can have it at .4 or 1.0, giving you completely different results.

And finally, I hope there will be a feature like "Test all values" and show them on the same page.

Promising

I like it for the most part so far, but when I go to assign a measurement to an asset and I have to scroll to the bottom assets, I’m unable to select them because the scroll bar doesn’t go down far enough. So any time I measure those assets I have to go in and do it manually from the “Data” screen. Please fix this. Other than that it’s extremely useful and has already saved me tons of time walking trays with liquid across the room, measuring, writing down measurements, going back and doing it over and over.
