This is the PRO-57, a highly versatile, economically-priced, handheld Tweezer Digital Multimeter. Small enough for one-hand operation, it is perfect for use on surface mount devices (SMD). It has a display of 3000 counts, 4 times per second sampling, automatic polarity with negative indication (-), battery status, and over-range indication. The PRO-57 can measure continuity, capacitance, and resistance, with an accuracy of 3% - 5%. It also has a diode test function.
- 3% ~ 5% basic accuracy depending on the range selected
- Diode test
- Overload protection and data hold
- Low battery indicator and auto power-off
