Be sure to report back on diode test voltage (would it kill them to put that number in the info??) and how loud the beeper is.  :)

It's unlikely that a meter power by 2 cells will forward bias a white LED.
The exception is the Fluke 18B+ which has a dedicated LED test range which outputs auto polarity 12V.

Why? Many DMM chips has a build in capacitive boost converter.
xavier60:
How they power the back light LEDs, didn't occur to me. Maybe some sort of capacitive boost converter.
I have just checked my AN8008 with a fresh pair of alkaline cells.
Oddly it outputs slightly more voltage on the Diode test range, 3.2V, than what I measure at the battery, 3.18V.
And it does light a white power LED at "2.451V".
It might even work with the NiMh cells when they arrrive.
