The PRO-57 Tweezer Digital Multimeter is a compact Digital Multimeter (DMM) with a tweezer form factor. Small enough for one-hand operation, it is ideally suited to measure Surface Mount Devices (SMD). Although the PRO-57 is much smaller and lighter than traditional multimeters, it is able to measure resistance in six ranges which are from 300 Ω to 30 MΩ, to measure continuity under 300 Ω, to measure capacitance in 8 ranges from 3 nF to 30 mF, and to test diodes. The Tweezer Digital Multimeter has Auto Check Mode which automatically switches to the applicable measurement for resistance, capacitance, continuity or diode test.
