Google for "PP3 explode"I've never known a 9V battery to do that or leak, so perhaps the key is to settle for zinc carbon batteries and replace then more regularly and that means as well that you get more stable pile type of construction.
A bit late to the disk drive party - but I've been pondering the question of will I share this...
Back in the 80's I was working for a company as an analyst/programmer after having spent 2 years as an operator on an IBM 370 system using 3340 disks. These disks always reminded me of the USS Enterprise.
@Mnem, sorry bd139, I did get there first, I was testing it while you were posting I guess.
The warning comes up at 6.4V but it carries on, reading correctly right up til the battery gets to 5.62V at which point it beeps at you and displays blanks to a error message.
Personally I'm pleased that it uses a 9V battery as these are less prone to leakage than single cells but if getting caught without a battery miles from anywhere is why you like Lipo batteries, you can get rechargeable 9V batteries that should provide pretty good battery life seeing as the current draw is around 6.5mA.
The leads are 1KV 10A rated and are silicon, tips are gold plated, I certainly wouldn't lose any sleep over the colour being red as opposed to yellow, I have meters here that are black, yellow, brown and now red, truth is that when you're using them, you totally ignore the colour, the only thing that you focus on is the display and the accuracy and colour has zero influence over those.
These meters are most certainly worth a shot, I have plenty of Flukes that I'm putting on Ebay soon and with the return on them, I'll think I'll be buying another 867 and maybe the PC interface and software, I very much doubt that I'll regret it.

Hmmm... I remember reading some testing on other meters that showed they started to have accuracy problems below 6V... but that's promising. I should be able to use a regular 600mAH 8.4/7.2V Nominal LiPo with it, which should last forever, even if I cheat and add a LED on a switch.
Very tempting, as my excursion to the local pawn shops yielded only a 179 for $220. And a HP DV6-2150US laptop supposedly dead (it's restoring to factory even now) for $15, and they threw in a T95N-MINI MX+ TV Box as well.
I think I'm gonna toddle off to ded now... my retail therapy just yielded even more crap I need to work on.

ZZZzzzZZZzzz...
Greenlee rebadges Brymen in the US, but they don't do it for all Brymen models. The Greenlee DM-860A is the Brymen BM869s. They don't do the BM867. The next one down is the Greenlee DM-830A, which I think is the Brymen BM829s.
It does appear that Greenlee made space in their model numbers for some more rebranding, though.

But surely aren't Lipo batteries just as dangerous as well?

I had a Fluke 77 destroyed by a leaking (not exploding) 9 V battery.
Our country is too small to have more than one time zone so we just have DST to make us feel better
Nah, NZT but we have DST over the summer months.
... The stuff the outer casing was made of was incredible. A full swing blow with a 21oz ball pein hammer just bounced off. ...

You lot even get summer wrong, whereas usually we don't get summer.
I was once in the computer room at Queen Mary College when they had total mains power failure. A loud computer room suddenly became somewhere you could hear a pin drop.

A full swing blow with a 21oz ball pein hammer just bounced off. ...Polycarbonate, intended as a containment mechanism if the disk decided to go totally Tonto at a few thousand RPM. Those spindles are basically flywheels and, depending on the drive model, weigh a few kilos to several hundred kilos. That, spinning at a few thousand RPM, has not insignificant energy bound up in its motion. It used to be a standard practice for bored technicians and programmers to pull out the specs for proper man sized disk drives, calculate the kinetic energy of the spindle at full working speed and work out how much of the building it would demolish on its way out if it ever broke free of its bearings.
I remember that, as I kid, I had a book on modern transport in which there was a bus that spun up a flywheel when breaking, and used the energy when pulling away. I presume that going round a corner wasn't too difficult, since by then the flywheel ought to have slowed down.
Looking good.
I got mine off eBay or out of my mule scope. Sphere sell them: http://sphere.bc.ca/test/tek-parts/tekpots.html (half way down)
