Learn how a multimeter measures volts, ohms, diodes, continuity, capacitance, and currents, including probe placement, ranges, DC/AC measurements, and testing BJT transistors with a PNP/NPN socket.
Learn to use a manual multimeter: place the red probe on voltage and current ports and the black probe on common, then measure voltage, resistance, capacitance, diodes, continuity, and transistors.
Learn to test polarized electrolytic capacitors with a multimeter in farad or continuity mode, identify polarity, and use a higher microfarad range to protect the meter and motherboard.
Learn to test smd tantalum and polarized capacitors with continuity mode, recognize normal low readings near chipsets, and distinguish them from shorts.
Learn to distinguish smd capacitors from smd coils by using labels C and L, color cues, and references to avoid confusion.
Explore how designators label parts, such as c for capacitors, l for coils, x/y for crystals, u for ic, q for mosfets, d for diodes, and r for resistors.
Use diode mode to test diodes, MOSFETs, and Zener diodes by locating the anode and cathode; verify expected drops (0.2 for diodes, 0.6 for MOSFET paths) and reverse-blocking behavior.
Switch the multimeter to ohm mode and adjust ranges to test resistors, including current sense resistors near 1 ohm, two ohm parts, and zero ohm resistors.
Electronics Repair: Test SMD Components with Multimeter (Capacitors, Diodes, MOSFETs & More)
This course will teach you how to test electronic components using a multimeter like a professional technician, even if you are a complete beginner.
