When you do repair or test PCB Board job, DIY others about relevant electricity product, You would need the digital multimeter to help you test and fix issues about electrons.
The DT9205A multimeter offers you several amplitudes of measurement with which to test electrical components for voltage, resistance or continuity. You can measure several different magnitudes of these quantities by adjusting the dial on the surface of the multimeter. The two most common uses for a multimeter are to test voltage and resistance. Using Ohm’s Law — the equation I=V/R, where I is current, V is voltage and R is resistance — allows you to derive current.
