I don't have an ESR meter, but have read (on here) various threads about the advantages of checking ESR.
Not to deviate, but I feel the ESR in caps is bound to increase over time and many pieces of electronics have caps with ESR much higher and don't show any signs of failure.
As for smart tweezers, are they more useful because of size, pointed tips, and not having polarity? Or are they useful because they have features you can't find in other meters?
If a component needs to be removed to measure correctly regardless if they advertise not needing to do this, a resistor is cut and dry. Any meter should read just about all resistor values (unless they are milli ohm values in which case you need a milli ohm meter). Inductors are a bit more tricky, but feel inductors will just burn open. The tricky ones I think are capacitors because they can be very tiny (a few pF) to very large.
I'm uncertain if I own a meter that can read a 1pF capacitor. Most of my repairs involving caps have been blown capacitors, but, as mentioned, I did come across the need to measure chip caps just to confirm their value (or need to confirm in a parallel circuit because a previous owner messed with it).
I'm just wondering if my money is better spent on smart tweezers, or, if I don't own a meter that can measure down to a pF, purchase one.
