When did "Hackable" imply complete information on what is to be hacked?
Don't confuse user programmable (it isn't) with hackable (which most things actually are, this one more than others).

Point taken, of course.
What I'm looking to do is actually to be able to automate measurements.
I e be able to read data from the unit and possibly "press some buttons" from say a python program.
Maybe something like this can be done via bluetooth?
GeoffreyF:
You certainly can get a stream of data through bluetooth. The protocols for that are documented.
pushing buttons - probably not so easy. You do have open schematics and so you could solder small wires to the button contacts or something like that. It seems to need reminding to some, for what it does the 121GW is not that expensive so - by all means hack the hardware. It won't be CAT anything if you do but it can be modified and then put into some kind of a case that supports the connections etc. That sounds like fun.
n3mmr:
Stream of data is what is needed for using in automated setups, so if I look at that doc on BLE, and the app's source on git, supposedly I only need a way to talk to bluetooth from python.
"Pushing buttons" was just that the fw in tx3 lets you do just that over a serial connection
I wouldn't dream of "hacking the hardware". I want it to work reliably.
GeoffreyF:
Hacking (or modifying) the software can interfere with reliability as well. I think the real point here is that you need to acquire something other than a hand held DVM.
