2.2 Njikọ Ndị Nnwale Nlele

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.

1. Maka ọtụtụ voltage, resistance, and low current measurements, connect the black lead to the 'COM' (Common) jack.
2. Connect the red lead to the 'V-Ω-mA' jack for voltage, resistance, and milliampnha ndị dị ugbu a.
3. 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.

3.1 Na-atụ DC Voltage (DCV)

1. Set the rotary dial to the desired DCV range (e.g., 200m, 2, 20, 200, 1000). Choose a range higher than the expected voltage.
2. Connect the red lead to the positive (+) side of the circuit and the black lead to the negative (-) side.
3. Gụọ voltage uru na ngosi.

3.2 Na-atụ AC Voltage (ACV)

1. Set the rotary dial to the desired ACV range (e.g., 200m, 2, 20, 200, 750). Choose a range higher than the expected voltage.
2. Jikọọ ụzọ ule n'ofe AC voltage source. Polarity does not matter for AC voltage.
3. Gụọ voltage uru na ngosi.

3.3 Measuring Resistance (Ω)

1. Hụ na sekit ma ọ bụ akụkụ ahụ anaghị arụ ọrụ nke ọma tupu ị tụọ ihe ndị na-eguzogide ya.
2. Set the rotary dial to the desired Ω range (e.g., 200, 2K, 20K, 200K, 2M, 20M, 200M).
3. Jikọọ ihe nlele ndị a ga-eji tụọ.
4. Gụọ uru ndị na-eguzogide na ngosipụta.

3.4 Measuring DC Current (DCA)

1. Jide n'aka na sekit ahụ anaghị arụ ọrụ nke ọma.
2. Set the rotary dial to the desired DCA range (e.g., 200µ, 2m, 20m, 200m, 10A).
3. Ihe dị mkpa: For currents up to 200mA, use the 'V-Ω-mA' jack for the red lead. For currents up to 10A, use the '10A' jack.
4. Break the circuit and connect the multimeter in series with the load. The current must flow through the multimeter.
5. Re-energize the circuit and read the current value.

3.5 Measuring AC Current (ACA)

1. Jide n'aka na sekit ahụ anaghị arụ ọrụ nke ọma.
2. Set the rotary dial to the desired ACA range (e.g., 200µ, 2m, 20m, 200m, 10A).
3. Ihe dị mkpa: For currents up to 200mA, use the 'V-Ω-mA' jack for the red lead. For currents up to 10A, use the '10A' jack.
4. Gbajie sekit ahụ ma jikọọ multimeter n'usoro na ibu ahụ.
