A look at the Uni-T UT210E
thierer:
First of all, thanks to everybody involved for all the valuable information in this thread. Made my UT210E so much more useful! :-+
Also, I'd like to give a quick heads up to anyone trying to do the modifikations on a linux machine (browsing the thread I haven't found any evidence of such a person, but anyway :))
I planned to follow Johnex's excellent walkthrough for a solderless method using a CH341A adapter and a test clip. I'm on Arch Linux and so I was happy to find an AUR package for commandtab's CH341A programming tool that claims to support the AT24C02A (it has a command line option to select it). Except it doesn't work... I then found danman's post which pointed me to plumbum's patches, that make the tool actually work for the AT24C02A.
I asked both commandtab to merge plumbum's fixes and the AUR maintainer to switch to plumbum's version. As a quick fix until either of these happen I made a modified version of the AUR package which uses plumbum's version.

i am using Linux,
all my machines are free of the devil's o.s. (m$)

Update: plumbum's fixes got merged, so no need to change the repository any more.

This doc is the result of explorations into modding the Uni-T UT210E Clamp Meter; it's what I'd wish I'd had before wading through pages and pages of forum posts and datasheets, all in at least three languages. It includes an example of modifying a UT210E using a Bus Pirate.

Thank's for your work ! :-+
I wait CH341A programmer for mods (noob inside :phew:).
Mortymore:
Did the mod today with an Arduino Uno and the sketch provided by jayjr1105, on reply #550 (pag23)
WARNING: Don't try this at home :scared:
I didn't solder any wires or used a clip. Just poke the pins into the 5 holes (they made good contact) and secured the one for reset, firmly against the capacitor (that goes to pin 55 of the DM1106)
You have been warned.
One thing that I've not read anyone talk about is about capacitance measurement (I read all the 26 pages, but sure some of the replies "in diagonal"). I didn't done any thorough test on accuracy. It seem fairly OK, but I was surprised by how fast the big capacitance as measured. An Amprobe AM-530-EUR take ages to measure the mF range. This got the job done for 40mF in few seconds.
Thanks to everyone that has given any kind of contribute for this mod to be at this stage.
I'm still thinking about Joe Smith's hack that stretched this probe up to 100KHz BW. Didn't quite get how it was done, but someone here (sorry I don't recall the nick) suggested a replacement of the quad op-amp OPA4330 for a AD8630. It has much higher BW. Despite the high cost of the op-amp compared to the low cost of the clamp, anyone has tried something like this?
