2. Ensure Bluetooth is enabled on your mobile device or computer.
3. Power on the OW18B multimeter.
4. Open the OWON application. The app should automatically detect and connect to the OW18B. Follow any on-screen prompts for pairing if necessary.
5. Setelah disambungkan, anda boleh view real-time measurements, log data, and analyze trends within the application.

5. Arahan Operasi

5.1 Hidup/Mati dan Pemilihan Fungsi

To power on the multimeter, rotate the function switch from "OFF" to the desired measurement function. To power off, rotate the switch back to "OFF".

5.2 Jldtage Pengukuran (AC/DC)

1. Connect the black lead to the COM jack and the red lead to the VΩHz jack.
2. Rotate the function switch to the V~ (AC Voltage) atau V- (Vol DCtage) kedudukan.
3. Sentuhkan prob ujian ke titik litar di mana voltage perlu diukur.
4. Baca voltage value on the display. The meter supports True RMS for AC measurements.

5.3 Pengukuran Arus (AC/DC)

Awas: Jangan sekali-kali sambungkan meter secara selari dengan voltage source when measuring current. This can damage the meter and pose a safety risk.

1. For mA: Connect the black lead to COM and the red lead to the mA jack.
2. For 20A: Connect the black lead to COM and the red lead to the 20A jack.
3. Rotate the function switch to the A~ (AC Current) or A- (DC Current) position.
4. Buka litar di mana arus akan diukur dan sambungkan meter secara bersiri.
5. Baca nilai semasa pada paparan.

5.4 Resistance, Continuity, Diode, and Capacitance Measurement

1. Connect the black lead to COM and the red lead to the VΩHz jack.
2. Rotate the function switch to the Ω (Resistance), →| (Diode), or •))) (Continuity) position. Use the "Select" button to cycle through these functions if they share a single switch position.
3. For resistance, connect probes across the component. For continuity, a beep indicates a continuous circuit. For diode, connect across the diode. For capacitance, connect across the capacitor.
4. Baca ukuran pada paparan.

5.5 Pengukuran Frekuensi dan Kitaran Tugas

• Siaran Suara: Enable this feature in the app settings to hear readings audibly, which can be useful in situations where viewing the display is difficult.

6. Penyelenggaraan

6.1 Pembersihan

Lap bekas meter dengan iklanamp cloth and mild detergent. Do not use abrasives or solvents. Ensure the meter is powered off and disconnected from any circuits before cleaning.

6.2 Penggantian Bateri

Refer to Section 4.1 for battery installation instructions. Replace the 9V battery when the low battery indicator appears on the display.

6.3 Penggantian Fius

If the current measurement function fails, the fuse may need replacement.

1. Ensure the multimeter is powered off and all test leads are disconnected.
2. Buka penutup petak bateri seperti yang diterangkan dalam Bahagian 4.1.
3. Locate the fuse(s) inside the compartment. The OW18B typically uses two fuses: a fast-acting 600mA/250V fuse for the mA range and a fast-acting 20A/250V fuse for the 20A range.
4. Carefully remove the blown fuse and replace it with a fuse of the exact same type and rating.
5. Gantikan penutup petak bateri dan selamatkannya.

6.4 Penyimpanan

Apabila tidak digunakan untuk tempoh yang lama, tanggalkan bateri untuk mengelakkan kebocoran. Simpan multimeter di tempat yang sejuk dan kering, jauh daripada cahaya matahari langsung dan suhu yang melampau.
