2.2 Proba-kableak konektatzea
The multimeter comes with two test leads, typically one red (positive) and one black (negative/common). Proper connection is crucial for accurate and safe measurements.
- Bolumen gehienarentzattage, resistance, and low current measurements, connect the black lead to the 'COM' (Common) jack.
- Connect the red lead to the 'V-Ω-mA' jack for voltage, resistance, and milliampegungo neurketak.
- For high current measurements (up to 10A), connect the red lead to the '10A' jack. Always ensure the correct jack is used to prevent damage to the meter or circuit.
