Component tester on oscilloscopes

(1/5) > >>

Axtman:
I see a few oscilloscopes with a component tester feature.  Is this just a gimmick or is it a useful accessory?

madires:
It's useful for a quick test and to find fishy components. You can also build such a tester yourself (quite simple) if your scope doesn't include one.

Fraser:
The component tester in Hameg scopes is most definitely not a gimmick if you know how to use it.

I have several Huntron Trackers and they cost significantly more than a used Hameg scope which offers a respectable alternative.

Look up Octopus testers for the theory of operation. The one in the Hameg is not as simple as some and performs better as a result.

kripton2035:
yes I compared two boards one working and one non working using the component tester of an hameg scope.
very useful for this job
useless if you want to measure a resistance or a capacitance with it.
what it lacks is the ability to store a trace, and compare it with another to find good/bad pcb
this feature is in the huntron but I wasnt able to pick one at a decent price.

DC5AJ:
Alan W2AEW did a great video about component tester / octopus tester. Check it out:   It explains the circuit and shows the resulting patterns of various components, maybe it is interesting for you.
