 Digital tweezers are compact multimeters designed specifically for testing surface mount components. Seeing how most surface mount passives are unlabeled and have a tendency to scatter when just breathed upon, these can be ridiculously handy. Of course, they also work for testing through-hole parts, across header pins, checking continuity on buttons and switches, the multimeter basics. This model here is a bit fancy, with resistor, capacitor, inductance, voltage, frequency, and diode modes along with a signal generator. Bonus. Even without the bells and whistles, I prefer using these over a regular meter because of the single-handed operation and no test leads to unravel. Aw, don't worry multimeter. We still love you.
