The U1252B has it's own non volatile buffer (very limited) to store the logged data, that can be retrieve using the dongle, but in order to get it live feed "AND" logging the data up to max storage of the connecting device like at your tablet/phone/pc, of course they need to be on all the time.

Personally rarely use it for logging, but for measuring dangerous voltage/circuit remotely, which has a safety of spark gap in meters.  :-DD

That likely would work.  The biggest issue would be battery life and the weak link there is the phone/tablet.  You can obviously plug that into a power source. 

My feeling, however, is that the reliability of this setup will be a bit low and this is why the data-logging I do for work has been switched to use USB/serial- optical cables connected a computer or Raspberry Pi.  I had use the U1117A many years back and at one time was running 3 simultaneously to my phone.  The app changed over time and some versions of it were not reliable.  There are so many different phone and tablet models as well as OS versions that I suspect it is a bit of a challenge to keep the software maintained.

I just snagged a 'new' Fluke 289 on eBay for just over $300.  It says it comes with TrendCapture, I've attached a picture from the eBay listing. Did I do OK?

Black Phoenix:
You've done an excellent deal. The "It comes with TrendCapture" is one of the features of the 287/289 family were you can log to the DMM and view the graphic of what you capture directly on the screen.

BravoV:
Agree, and once you do lots of logging, especially at the field, worry you will abandon the cumbersome of using your Agilent DMM + U1117A module + PDA/phone/laptop.  :P
