OT what is that vibrating sensation you get when you lightly touch the metal on a mains appliance?

Hi,

You really need to prove the appliance earth and the supply earth are OK.

cheers, Pete.

I have to say I have my reservations about it being 1950s with MCBs though :) Possible I suppose, but my gut feeling is 'are you sure?' I can just imagine an MCB feeding the electrode heater that supplies the bath :)

Well high impedances were always claimed - but I technology might've moved on a little since I bought this for 10/6.

Mostly it only gets used for continuity testing nowadays but I'm getting tempted to take a look.

Hmmmm. I apologise. I've realised that I was talking nonsense (it's not unusual). The house was built in the 50s. I found evidence (in the loft) that old wiring has been replaced with what I recognise as modern wiring. Yes, there is a CU with MCBs. I was not involved in the rewiring but there don't appear to be other issues. (Well there was one - and I almost won a Darwin Award when I discovered it!)

How do you know? Are you in Hampshire? Birmingham? ;-)

Now that the antibiotics have kicked in & my blood stream is no longer so toxic I can see the cr@p I was writing - apols.

Forgiven! ;-)

That's a fair size house if it stretches from Hampshire to Birmingham, I don't live inbetween those places though.

Why would I have used Google?

Thought I could lay my hands on an old list, but can't. However, if it's the same as an AVO model 8, these batteries come up on ebay.

Just a bit - most cheap meters these days are near enough the equal of a valve voltmeter of old. About 10 Meg input.

Most DVMs have a proper continuity tester with a buzzer that sounds below a preset resistance.

Nothing on Ebay but wayheyhey!!! Last time I did a search for this all I could find were references to it having been discontinued but today there it is on sale at

:))

It's gonna be cheaper to buy a new DVM than to buy a replacement battery for my museum piece. ;-)

Ah, I'm ACS Ltd in Sheffield, but I don't live there! (Some people will notice I do have a fair old bit of commuting)!
