Picoscope 2205 fried "ground bridge"

Postby HansM » Wed Jun 06, 2012 11:34 am

Hi,

I accidentally fried a smd component when connecting +12v to channel A ground. There is a component that look fried, and picoscope works fine when shorting this component. Anyone knows what kind of component and values this is? similar components on channel B measures 0 ohm, making me believe it is some kind of smd fuse? See attached picture, the one in the red circle is fried and the ones in yellow circle is similar!

It is indeed a 0 Ohm resistor and they are used as bridges. In this case, they seem to be used as fuses too, yes.

However, as above - send it for repair though, as I'd expect it'll be tested for any further damage that may not be immediately obvious.

Exactly what it is for, just easier to use these than a piece of wire. You can send it in if you want us to look at it or just replace the part yourself.
