2.2 Lidhja e Përçuesve të Testimit

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. Për shumicën e vëllimevetage, 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 milliampmatjet e rrymës.
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.

3.3 Matja e Rezistencës (Ω)

1. Sigurohuni që qarku ose përbërësi të jetë i çaktivizuar para se të matni rezistencën.
2. Set the rotary dial to the desired Ω range (e.g., 200, 2K, 20K, 200K, 2M, 20M, 200M).
3. Lidhni telat e provës nëpër përbërësin që do të matet.
4. Lexoni vlerën e rezistencës në ekran.

3.4 Measuring DC Current (DCA)

1. Sigurohuni që qarku të jetë i çaktivizuar nga energjia.
2. Set the rotary dial to the desired DCA range (e.g., 200µ, 2m, 20m, 200m, 10A).
3. E rëndësishme: 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. Sigurohuni që qarku të jetë i çaktivizuar nga energjia.
2. Set the rotary dial to the desired ACA range (e.g., 200µ, 2m, 20m, 200m, 10A).
3. E rëndësishme: 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.
5. Re-energize the circuit and read the current value.

3.6 Measuring Capacitance (CX)

1. Sigurohuni që kondensatori të jetë shkarkuar plotësisht para testimit.
