3. Persediaan

Pemasangan Bateri:

The Avidsen 107101 multimeter operates on a 12V battery (Type 23A). To install or replace the battery:

1. Pastikan multimeter dimatikan dan petunjuk ujian diputuskan.
2. Cari penutup petak bateri di bahagian belakang peranti.
3. Carefully remove the screw(s) securing the cover and open it.
4. Insert the 12V (Type 23A) battery, observing the correct polarity (+ and -).
5. Gantikan penutup petak bateri dan kencangkannya dengan skru.

Menghubungkan Petunjuk Ujian:

Connect the red and black test leads to the appropriate input jacks on the multimeter. The black lead typically connects to the 'COM' (common) jack, and the red lead connects to the 'VΩmA' jack for most measurements.

4. Arahan Operasi

To operate the multimeter, turn the rotary switch to the desired function and range. The display updates measurements approximately twice per second.

4.1. AC/DC Voltage Pengukuran:

1. Connect the black test lead to the 'COM' jack and the red test lead to the 'VΩmA' jack.
2. Turn the rotary switch to the desired ACV (Alternating Current Voltage) or DCV (Direct Current Voltage) range. Select a range higher than the expected voltage.
3. Connect the test probes in parallel across the circuit or component to be measured.
4. Baca voltagnilai e pada paparan digital.

4.2. DC Current Measurement:

1. Connect the black test lead to the 'COM' jack and the red test lead to the 'VΩmA' jack.
2. Turn the rotary switch to the desired DCA (Direct Current Amperage) range.
3. Penting: Connect the test probes in series with the circuit. Break the circuit and insert the multimeter.
4. Baca nilai semasa pada paparan digital.

4.3. Pengukuran Rintangan:

1. Connect the black test lead to the 'COM' jack and the red test lead to the 'VΩmA' jack.
2. Turn the rotary switch to the desired Ω (Ohms) range.
3. Penting: Pastikan litar atau komponen dinyahtenagakan sebelum mengukur rintangan.
4. Sambungkan kuar ujian merentasi komponen yang hendak diukur.
5. Baca nilai rintangan pada paparan digital.

4.4. Ujian Diod:

1. Connect the black test lead to the 'COM' jack and the red test lead to the 'VΩmA' jack.
2. Turn the rotary switch to the diode symbol (usually a triangle with a line).
3. Sambungkan kuar merah ke anod dan kuar hitam ke katod diod. Paparan akan menunjukkan vol ke hadapantage penurunan.
4. Balikkan prob. Paparan hendaklah menunjukkan 'OL' (Beban Lebih) untuk diod yang baik.

4.5. Transistor Gain (hFE) Measurement:

This function allows you to measure the DC current gain (hFE) of NPN and PNP transistors.

1. Turn the rotary switch to the 'hFE' position.
2. Identify the Emitter (E), Base (B), and Collector (C) terminals of the transistor.
3. Insert the transistor leads into the corresponding sockets in the hFE test socket on the multimeter, ensuring correct NPN or PNP type selection.
4. Read the hFE value on the digital display.

4.6. 50 Hz Square Wave Generator:

The multimeter can generate a 50 Hz square wave signal for testing purposes.

1. Turn the rotary switch to the '50Hz Square Wave' position.
2. The square wave output will be available at the 'VΩmA' and 'COM' jacks.
3. Connect an oscilloscope or other suitable device to observe the generated waveform.

5. Penyelenggaraan

Pembersihan:

Lap peranti dengan iklanamp cloth and a mild detergent. Do not use abrasive cleaners or solvents. Ensure the device is dry before use.

Storan:

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.

6. Penyelesaian masalah

• Tiada Paparan: Check battery installation and ensure the battery has sufficient charge. Replace if necessary.
• 'OL' or '1' on Display: This indicates an overload or out-of-range measurement. Select a higher range or check for an open circuit.
• Bacaan yang salah: Verify the correct function and range are selected. Ensure test leads are properly connected and not damaged. Check the battery level.
• No Square Wave Output: Ensure the function is correctly selected and connections are secure.
