5. Cov lus qhia ua haujlwm

5.1 Fais fab rau / tawm thiab xaiv muaj nuj nqi

To power on the multimeter, rotate the central rotary switch from the 'OFF' position to the desired measurement function. To power off, rotate the switch back to 'OFF'.

Duab: pem hauv ntej view of the Jauarta MY8236B Digital Multimeter, highlighting the central rotary switch for function selection and the digital display.

5.2 Ntsuas DC Voltage (V–)

1. Set the rotary switch to the 'V–' range. Select an appropriate range (e.g., 4V, 40V, 400V) higher than the expected voltage. Yog voltage tsis paub, pib nrog qhov ntau tshaj plaws thiab txo qis raws li qhov xav tau.
2. Txuas tus xaim liab rau sab zoo (+) ntawm lub voj voog thiab tus xaim dub rau sab tsis zoo (-).
3. Nyeem voltage tus nqi ntawm cov zaub.

5.3 Ntsuas AC Voltage (V∼)

1. Set the rotary switch to the 'V∼' range. Select an appropriate range higher than the expected voltage.
2. Txuas cov xov hlau kuaj hla AC voltage qhov chaw.
3. Nyeem voltage tus nqi ntawm cov zaub.

5.4 Measuring DC Current (A–)

Ceev faj: Tsis txhob txuas lub multimeter ua ke nrog lub voltage source when measuring current. Always connect it in series with the load. Ensure the correct input jack (VΩmA or 10A) is used.

1. Tua lub zog rau lub voj voog.
2. Break the circuit at the point where current is to be measured.
3. Set the rotary switch to the 'A–' range (e.g., µA, mA, or 10A).
4. Connect the red test lead to the appropriate current input jack (VΩmA for up to 400mA, 10A for up to 10A).
5. Connect the multimeter in series with the circuit.
6. Restore power to the circuit and read the current value.

5.5 Measuring AC Current (A∼)

Follow the same safety precautions and connection method as for DC current, but set the rotary switch to the 'A∼' range.

5.6 Kev Ntsuas Kev Tiv Thaiv (Ω)

Ceev faj: Ensure the circuit is de-energized before measuring resistance. Do not measure resistance on a live circuit.

1. Turn off power to the circuit or component.
2. Set the rotary switch to the 'Ω' range.
3. Txuas cov xov hlau kuaj hla lub Cheebtsam lossis lub voj voog uas yuav ntsuas.
4. Nyeem thev hauj tus nqi ntawm cov zaub.

5.7 Kev Ua Haujlwm Tshwj Xeeb

• Khawm FUNC: Used to switch between different functions within a single rotary switch position (e.g., AC/DC, Diode/Continuity).
• HOLD khawm: Kho qhov nyeem tam sim no ntawm qhov screen. Nias dua kom tso tawm.
