Why can''t capacitors on PCBs be measured with a multimeter?
They are promoting ESR meters so they are talking about capacitors. Since the ESR of a good electrolytic power supply capacitor is typically in the low single-digit ohms or less you can practically test it in-circuit, which saves time and prevents damaging the board if the cap is good. Testing the capacitance in-circuit is often not possible.
