The Smart Tweezers (ST) are indeed smart. The automatic mode correctly identifies resistors, capacitors and inductors and displays their values. STs can measure leaded components and surface mounted components and also work well with in-circuit measurements. Traditionally, in-circuit measurements are "iffy" but STs offer manual modes and control of the test frequency, the test voltage, and the resistance of the internal signal generator. For example, the user can reduce the amplitude of the test frequency which can improve in-circuit measurement accuracy (the amplitude can be reduced to as low as 250 mV to avoid turning on solid-state junctions). Of course, in-circuit measurements can still be tricky due to parallel components.
ESR is an issue with electrolytic and tantalum capacitors. STs perform wonderfully for ESR measurements.
The diode mode is way cool as the schematic symbol for a diode is shown on the LCD display and lo and behold the symbol changes to correctly identify the cathode and anode leads. Using this mode usually works well to verify both in-circuit diodes and out-of-circuit diodes.
Some audio technicians use impedance meters to test speakers and 70.7 volt audio distribution systems. Smart Tweezers are usable for these situations. One can hear the test signal coming from the speaker.
In-circuit probing of SMT devices is the best. The tips are gold-plated and very sharp. Out-of-circuit probing/sorting of SMTs is also great ... have you ever wondered what those little chips left on your work bench are? Have you ever inadvertantly swept those little buggers onto the floor when your instrument leads dragged across them?
STs are not cheap but, when you consider the functionality, the accuracy (traceable to NIST), the ease of use, .... a great instrument and a solid investment, in my opinion.
