Introduction
The Digital Multimeter is the most versatile tool in electronics. It helps you verify if your circuit is receiving power and if components are working.
Measurement Modes
- Voltage (V): Measured in parallel.
- Resistance (Ω): Measured with power OFF.
- Current (A): Measured in series (breaking the circuit).
- Continuity (♪): Checks if two points are electrically connected.
Safety Rules
- Never measure current in parallel with a power source (it will blow the fuse!).
- Always check the range setting before measuring high voltages.
- Discharge large capacitors before measuring resistance.
