Fluke meter battery
Well, it was suggested that the horizons of this forum be broadened:-
I have just discovered the battery in my Fluke 77 has died. Googling brought nothing remotely useful. Anywhere (not eBay) in the UK I can get a replacement?

As far as I know the Fluke 70 series take a standard 9v battery. The 75II in my car certainly does

I have a Fluke 77 (series 3) DMM and it takes a standard PP3 9V battery which is available in just about every electrical shop and supermarket in the UK.
Is yours one of the early models?, and if so, what number is shown on the old battery?

Check here for the specs
Fluke 77 multimeter
From experience they all tend to use 9V batteries
Now AVOs, that's a different kettle of fish

As far as I know the remarks about it being a standard 9v alkali battery are right. I have a Fluke 87 which certainly has. I had a problem recently, my battery was still working OK but I saw it was in for two years, I make a note on the back of the meter. I opened the case and the battery terminal was corroded onto the battery. The terminal fitting is a low grade affair compared with what else is in the case. You may find you have to buy another terminal fitting and graft it on to the old wires.

Yep, 9v on every one I've seen.
Just a quick By the Way.
These meters are prone to the LCD panel going a bit wishy-washy. There are replacements advertised on e-bay for about $20 Buy Now price. Check that the brush strip is clean before shelling out though.

Thanks for all the helpful information, chaps!
I must confess that I've not opened it yet, so the news that it's a standard PP3 is a little embarrassing. I was told it was a special battery and I must confess that the fact this one has lasted about 20 years tended to support that thought.

Googling brought nothing remotely useful
Which reminds me: when I was a mere youth, 9V batteries were generally piles: a stack of 6 little lozenges that left nasty marks on everything they touched. Nowadays, they tend to consist of six AAAA cells, and the cheapest way of buying such cells.

Google didn't even bring up fluke.com! (Well, not in the first six screens of useless info.)
I searched on "Fluke 77 battery" and then changed battery for spares, and it brought up mostly US meter sales sites.
Think I will rename Google 'suppository' on my computer - for all the good it does me, I might as well stick.............

It's funny, I'd just finished saying that there didn't seem to be anything that Google couldn't find.

Oh, and some of the things I post on PpruNe!

Sort of on topic - does anyone know how to get at the battery on an AVO digital Pro meter? The old type analogue are easy although the batteries aren't available everywhere but the digi version has got me stumped. Any thoughts, please?

Could try Rapid Electronics at Colchester, since they have stocked the old 15v for some time. ( I'm going back a bit, but always found they lived up to their name)

Never tried this, but was told that you could use it as a variable fuse (when doing current measurements). Just pop the button back in should it exceed the max

I got four of them last year, but I can't for the life of me remember where from.
Anyway, my two Avos, and two friends', are OK for a few years.

For Pete's sake don't use the moving coil AVO, ie the 8, as described. The method of calibrating that MECHANICAL circuit breaker gives about 2.5 times f.s.d. on the movement.
I've always made myself stand in the norty corner when I pop that.
The Rapid page does show the older type, but I wondered if they may stock more up to date stuff now.
BTW...They started in a Nissan hut near Boxted airfield 20 or so years ago. It's a sight to behold now.

Mine's a Fluke 73, same 9V battery.
Still works perfectly, but since I don't use it often, the battery must be at least ten years old, if not more.
I'll open it up and check, just in case.
