UNI-T UT61E Multimeter teardown photos.
multiJ:
That is very helpful, much appreciated

Brand new UT61E, bought on ebay, shipped directly from Shenzen. Markings on PCB: 150507-9 61E
When measuring clear DC on voltages above about 8 volts, I get this erratic readings on AC range, goes OL and back with beeping when OL is displayed. I have no idea what the problem is. Sorry no sound this is the only camera I got.

It's normal, the meter is not designed to measure AC voltage when there's DC voltage present as well.
This, plus the rare incorrect display for one reading when it changes ranges are the only "major" issues this multimeter has. The high burden voltage on some ranges (as explained above) I consider minor issue, easily to work around.

I had one bought 2 years ago that was in the same circumstances reading O an AC, wasn't jumping as this one. Can't remember what revision PCB was.

My 6F22 9V battery just died, 6 months after buying the meter (I use it a lot).
What is the best battery in this format? I saw http://www.fasttech.com/products/1046603 which is cheap.
I also saw http://www.fasttech.com/products/0/10002905/1812000-soshine-650mah-9v-li-ion-rechargeable-battery which is more expensive but might be a better deal in the long run?
Funny thing is that my smoke detector started beeping a few days ago even though the battery still shows 9.1V open circuit. (Bad design?)
I think I'll use new batteries in the smoke detector and then place them in the multimeter...
