From reading and watching, my take on the Uni-T UT61E is:
-solid, sturdy, feels great in the hand
-terrible high voltage protection; meter will (usually) die or (rarely) blow up when subjected to high voltage. Not recommended for electricians, or anyone that may regularly work with high voltage. The board was designed for better high voltage protection and has holes for both MOVs and larger fuses, but they have not been installed. At least one person has upgraded his meter himself.
. Some have suggested that the meter sold in the European Union has the upgraded parts.
-22,000 count provides extra degree of resolution (not accuracy).
-meter is usually within spec from factory, but can be tuned to higher accuracy.
-meter has no backlight (abysmally stupid) but ingenious EEVBlog contributor has created a nice proximity switch based solution.
https://www.eevblog.com/forum/testgear/uni-t-ut61e-backlight-mod-with-touch-sensor-(tutorial)/-meter will output data to an RS-232 port on your computer. Note: no one outside of China has an RS-232 port on their computer. I've purchased an RS-232 to USB adapter, and will report on how it works. RS-232 ports can also be purchased on a PCIe expansion card. (They come from China, where they're apparently quite popular.)
-Software supplied with meter is quite limited; a better choice is UltraDMM from ultradmm.com, which can be downloaded and used without cost.

I've also purchased this "High Precision Voltage Reference Module" from AliExpress for about $5.00.
https://www.aliexpress.com/item/AD584-High-Precision-Voltage-Reference-Module-4-Channel-2-5V-7-5V-5V-10V/32672069416.htmlIt's an AD584 based unit which provides very precise 2.5, 5.0, 7.5, and 10.0 volt outputs. I haven't been able to find official precision or accuracy statements, but it is apparently superior to a silver oxide battery (which, I'm told, has a very flat response curve). My past experience with AliExpress leads me to believe that I won't see it until March; but when it shows up I'll report on the results.
