in-circuit capacitor/resistor tester suggestions?

gogofast said:
as for testing resistors, how well does it work?
is there a separate resistor tester out there? since capacitors can be replaced when in doubt, but with so many resistors....

These ESR meters can be used for measuring .01 to 99 Ohms, is a decent low Ohms meter, but for checking resistors I think a regular ol' DMM, or Volt-Ohm meter suits that purpose.

Some of the stuff I've worked on has dozens of capacitors, not too practical to replace them all when only one or a few of the same type usually are the cause of the problem I am working on. I go through the boards with the ESR meter and a black felt-tipped marker, mark the ones that test bad with a dot, and replace those, which restores performance almost always.
