2.2 Konnessjoni tal-wajers tat-test
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.
- Għal ħafna mill-volumtage, 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, reżistenza, u milliampkejl tal-kurrent ere.
- For high current measurements (up to 10A), connect the red lead to the '10A' jack. Dejjem kun żgur li qed tintuża l-ġakk korretta biex tevita li ssir ħsara lill-miter jew liċ-ċirkwit.
