In circuit testing tools for PCBs?? Can it be done?

[fastline]

The more stuff I end up repairing, the more I want to have a way to test in circuit. Are there meters that can test in circuit? Cap, resist, diodes, etc? I honest cannot see how this is possible but thought I would ask.

If I understand what you mean, Try looking at those smart twezers. But there not cheap.

A FLUKE is good. A beep to show a Semiconductor junction is working properly.

An Analogue meter is better and more reliable for testing Semiconductor junctions for forward bias, leakage etc. Shoot me down.

Waiting for it....

That looks more like a micro multi meter??? Is that accurate?

I think I am more looking for something that can test components in circuit or assembled in a PCB. Very difficult to test cap or resis while a component is in a PCB. Just wondering if there are tools out there for that?

I believe the ESR tool below can test certain components in-circuit.
Peak Electronic Design Limited - Atlas ESR PLUS - Equivalent Series Resistance Meter and Capacitor Analyser with Audible Alerts - Model ESR70
I know Nigel has one and praises it highly, although he will certainly correct any erroneous info...

HTH.
