4. Soma thamani ya kipimo kwenye onyesho la LCD.
5. After measurement, disconnect the test leads and turn the multimeter OFF.

6.1 Kazi Maalum za Vipimo

• DC Voltage (V=): Select the V= range. Connect the red lead to the positive side and the black lead to the negative side of the DC voltage chanzo sambamba.
• Voltage (V~): Select the V~ range. Connect the test leads across the AC voltage source in parallel. Polarity is not critical for AC voltage.
• DC Current (A=): Select the A= range (mA or 10A jack). Disconnect power to the circuit. Open the circuit where current is to be measured and connect the multimeter in series. Reapply power.
• AC Current (A~): Select the A~ range (mA or 10A jack). Follow the same series connection procedure as for DC current.
• Upinzani (Ω): Select the Ω range. Ensure the circuit is de-energized. Connect the test leads across the component to measure its resistance.
• Mtihani wa Mwendelezo (♫): Select the continuity function. If resistance is below approximately 50Ω, the buzzer will sound, indicating continuity.
• Mtihani wa Diode (→|→): Select the diode function. Connect the red lead to the anode and the black lead to the cathode of the diode. The display will show the forward voltage drop. Reverse the leads; the display should show 'OL' (open loop) for a good diode.
• Uwezo (F): Select the F range. Ensure the capacitor is discharged before connecting the test leads.
• Mara kwa mara (Hz): Select the Hz range. Connect the test leads across the signal source.
• Halijoto (Kijoto): Select the Temp range. Connect a K-type thermocouple (if included or purchased separately) to the VΩHzTemp and COM jacks.
• Transistor hFE: Insert the transistor's emitter, base, and collector leads into the corresponding holes in the hFE socket, ensuring correct NPN/PNP type selection.

7. Matengenezo

7.1 Ubadilishaji wa Betri
