Wonder what battery life it gets with a lithium coin cell?
Wonder what battery life it gets with a lithium coin cell?
Current draw varies depending on function, but worst case (not continuity beeper sounding) is 2.2 mA. This isn't too terrible for the CR2032 cells according to this datasheet:
https://cdn-shop.adafruit.com/datasheets/maxell_cr2032_datasheet.pdf It should get 200 mAh-- it should get around 100 hours or more.
That looks pretty good!
UL listed too!
Who is the EOM for this?
Available under other brands?
Not quite a pocket meter in my book as it has separate leads, but very small.

The UEI DM5B has separate leads too, wouldn't you call that a pocket meter?
https://www.amazon.com/Test-Equipment-Pocket-Digital-Multimeter/dp/B000B6OL30The DMMW3 is about the same width and length as the DM5B, but it's thicker to accommodate the shrouded test leads and peripheral blast shielding.
I don't know who actually makes this meter for Southwire, it seems to be a unique design of their's contracted to some production house in China, I can't find any other version of it. Southwire does make other meters that I haven't seen elsewhere too:
http://nextgenmeters.southwiretools.com/While I've never heard of them, Southwire has been around for a long time:
http://www.southwire.com/ and "Woods" is one of their trademarks. They've got smartphone apps too:

Might pick one of these up for my father next time I am at a Lowes.
So... what's the dimensions?
If we're talking about separate leads and a pouch then a Fluke 101 isn't exactly huge.
(130 mm x 65 mm x 27mm to be exact)

The graphics look very much like CEM/Extech

According to the CEM webpage?H*W*D?:115mm x 60mm x 16mm

OK, so... about half the volume.

It measures 115mm x 60mm x 15mm -- measured to the top of the knob it's 19mm
It feels very solid for such a small meter and the display is excellent (but not backlit
)
Curiously the advertising photos shows it with a MAX button and a RANGE button, but in fact is has a "Hz/%" and a "REL" button respectively. It's always auto ranging and there's no min/max function.

Apparently this is a modification of CEM's DMP-3x series of pocket meters:
http://www.cem-instruments.com/en/Goods/detail/id/686/pid/768/pids/1136#Modified for UL compliance no doubt, by adding an HRC fuse and maybe other protection.
CEM's sure makes a lot of multimeters:
http://www.mgi.com.uy/images/pdf/cem-instrumentos-digitales/cem--multimeter.pdf Check out that DT-9998 on the last page. Wow, everything but the kitchen sink!
The full version of this meter looks pretty cool (I think that this is a DMP-33 despite the labeling on the face)
I live near a large Lowes. I'll see if they have one in stock and run it if they do.
I look forward to Joes review. Depending on how well it fares, i might pick one up. So I have one to keep in the car.

I find it has about the same functionally as a couple of other pocket DMM's I have: the UEI DM5B and the UNI-T UT120C.
All are small, within spec on all ranges and all have awful continuity beepers. The Southwire DMMW3 stands out because it has a much better feel to it, has serious input protection and comes with relatively decent leads for a pocket meter (and can use any test leads). However it is about 50% thicker than the other two meters.
Only had time to do a quick google search for the fuse pictured in one of the open case photos above.
"astm hv510.0.2 fuse"
So far all I found was a PDF link for ASTM fuses, in the list it shows the 200ma fuse as "510.0.2"
Hope these fuses are not hard to find. Looks like a decent backup meter, for a coat pocket.

They had a fairly large selection of meters in stock at the local store.
If there is anything you would like me to check, now is the time to ask. I'm getting close to the destructive part of the testing.

LIGHT THE CANDLE! 
Now that is confidence!
I am using the free HR meter, 101 and 107 as a comparison. Plan is to use the new ESD gun and retire the grill starter. If it fails (no EMC cert from what I saw) then I will run the 101 and 107 (HF meter would fail for sure).

Yeah, that DMP-33 caught my eye. I was wondering how it compared to the Southwire Woods model, but since I could not find it for sale anywhere, I gave up.
