I have not said this and is not to be done under any circumstances  :Doh:

what we used to do when using a scope on floating ccts was to use marigolds ( proper kite marked ones ) and disconnect the earth on the scope  :zap:

we did the same thing with our soldering irons ( before we got the isolated weller ones )


if you even think of doing the above take care


I guess from my posts I am of the old school sparks before H&S got into there swing , we had to sort it at the iron works it was 75 tons of molten CI at the bank it was the down time and pride

No doubt that was Stanton & Staveley ?

Yes we used to have the earth wire deliberately and very obviously poking out of the top of the 13a plug top so we could float the chassis of the 'scope when I worked for Ferranti all those years ago. I don't think that this fuse blowing was anything other than old age - it just happened when I turned the 'scope on and it was not connected to anything at the time.

 10/10 for your deduction powers

Andrew
if you are struggling with using the scope with a normal probe due to floating voltages if have got a pico battery powered differetial scope probe if you want to borrow it.
Its alot easier to loan that than my 1kva isloation transformer ( she weighs4or5kilos).
If you do want to borrow it pm me and ill drop in the post on saturday morning .im not using it at the moment, and the post will only be a couple of quid each way, you can have it till the end of may it it will help.

Best regards
Fred

awemawson:
Fred that is a very generous offer - thank-you. Let me hold that option in reserve - I'm bracing myself to apply your other suggestion of a side by side comparison of the other unit.
