Hi,
I bought this Agilent U1211A clamp meter as untested and possibly not working on ebay.
Well the package arrived and as soon as I opened it up I could smell that something was burnt inside it!
But it only cost £10 plus post so not to worry too much.
It even came fitted with a battery. On power on the display works and the Ohms range with the probes connected is working perfectly. The problem is with the DC and AC volts ranges.
As you can see below it has had a major overload of some description.
Good
Not so good.
Major burning to the PCB tracks under the range selector switch.
Switch
Input PCB
Display PCB
So any guesses to how the previous owner managed to overload a 1000V input meter? Perhaps on something higher than 1000V?
I suspect it made them jump when it went bang!
Now is it possible to repair PCB traces and how do you attempt to do so?
I have not tested the clamp part yet. I need to fix one of the CT wires I broke removing the PCB. It did not seem very well attached to start with.
