Fixing electronics? This handy little tool tests capacitors right on the circuit board (in-circuit) for a key failure metric called ESR (Equivalent Series Resistance). It also works as a low-ohm meter from 0.01 to 100 ohms. The MESR-100 V2 auto-ranges, so you just clip the leads on and it gives you a reading. It's a huge time-saver for diagnosing bad caps in power supplies, motherboards, TVs, or audio gear without having to desolder everything. Dual banana jack terminals make it easy to use. Comes with a printed ESR chart for reference. A must-have for any serious hobbyist or repair tech working on modern electronics. Simple, effective, and affordable.
