Electrical Test Equipment

[FarmerPug]

I found this in the attic the other day, it was sitting in a box but it had no writing on it, after putting a battery onto it, it does light up read voltage and test resistance even doing a bleep test, its some form of multimeter. but exactly what it would be used for i don't know:

Just looks like a basic multimeter to me.

Just looks like a basic multimeter to me.

It seems to only do voltage, resistance and capacitance tests. Im not sure of the brand though all that can be made out is its swiss made.

from the poor google translater ( with other selected words that means the same ) :

erst testen dann prufen

means :

Only to test then examine

Thanks for the translation, that must be some sort of warning then.
This is stuff that belonged to my uncle, he built and lived in our house but then we bought it off him, sadly he died a few years later so the attic is still full with old stuff of his, he had a lot of broken electrical things, but this was in a box.
There is also this clamp meter:

It can do voltage in AC and DC, as well as the resistance/continuity check but the clamp bit when i put it round the toaster at 4 slices isn't picking anything up.
Im looking to put them on ebay but have no idea what they are worth, the digital one is too awkward with the probe fixed to the casing and this other one is too hard to read.

Clamp meters only work on one live conductor.

I.e. put it through live and neutral and they cancel eachother out. You need to clamp it round just live or just neutral.

[jonsowman]

A current clamp needs to go on either the live or the neutral cable. Putting it around the entire mains lead (containing live, neutral and earth) won't give a reading.

Try it on the cables into your consumer unit or fusebox, these are normally separate live/neutral

Edit Beaten to it!

[FarmerPug]

that makes sense the two cancelling each other out
I tried it on the consumer unit:


Thanks for the help.
