4. Persediaan

4.1 Pemasangan Bateri

The Woods AMMW1 requires 1 AA battery (included) for operation. To install or replace the battery:

1. Ensure the multimeter is turned off (selector switch to OFF position, if available, or a non-measurement range).
2. Cari penutup petak bateri di bahagian belakang unit.
3. Remove the screw(s) securing the cover and carefully open it.
4. Insert the AA battery, observing the correct polarity (+ and - markings).
5. Replace the cover and secure it with the screw(s).

4.2 Menghubungkan Petunjuk Ujian

• Masukkan petunjuk ujian hitam ke dalam COM (Umum) jek.
• Masukkan petunjuk ujian merah ke dalam VΩmA bicu untuk kebanyakan ukuran (volumetage, resistance, current).

5. Arahan Operasi

Before taking any measurement, ensure the test leads are correctly connected and the rotary selector is set to the appropriate function and range.

5.1 Mengukur DC Voltage (V-)

1. Set the rotary selector to the desired DC Voltage (V-) range (e.g., 2.5V, 10V, 50V, 250V, 500V). Choose a range higher than the expected voltage.
2. Sambungkan petunjuk ujian merah ke sisi positif (+) litar dan petunjuk ujian hitam ke sisi negatif (-).
3. Baca voltage value from the appropriate DCV scale on the analog display.

5.2 Mengukur Vol ACtage (V~)

1. Set the rotary selector to the desired AC Voltage (V~) range (e.g., 10V, 50V, 250V, 500V). Choose a range higher than the expected voltage.
2. Sambungkan petunjuk ujian merentasi vol ACtage sumber.
3. Baca voltage value from the appropriate ACV scale on the analog display.

5.3 Mengukur Rintangan (Ω)

1. Set the rotary selector to the desired Resistance (Ω) range (e.g., 10x Ω, 1000x Ω).
2. Short the red and black test leads together.
3. Laraskan OHMS ADJUST knob until the needle points exactly to '0' on the OHMS scale. This zeros the meter.
4. Connect the test leads across the component whose resistance you wish to measure. Ensure the component is de-energized.
5. Read the value from the OHMS scale and multiply it by the range multiplier (e.g., x10, x1000).

5.4 Measuring DC Current (mA, µA)

1. AMARAN: Jangan sekali-kali menyambungkan multimeter secara selari dengan voltantage source when measuring current. Always connect it in series with the circuit.
2. Set the rotary selector to the desired DC Current (mA or µA) range (e.g., 500 µA, 10 mA, 250 mA).
3. Break the circuit where you want to measure current.
4. Sambungkan multimeter secara siri dengan litar, pastikan wayar merah menuju ke arah potensi yang lebih tinggi dan wayar hitam menuju ke arah potensi yang lebih rendah.
5. Read the current value from the appropriate scale.

5.5 Battery Testing (1.5V, 9V)

1. Set the rotary selector to the 1.5V BATT or 9V BATT kedudukan.
2. Insert the battery to be tested into the corresponding battery test sockets, observing polarity.
3. Read the battery condition from the dedicated "BAD / GOOD" scale on the analog display.

6. Penyelenggaraan

6.1 Pembersihan

Lap kes dengan iklanamp kain dan detergen lembut. Jangan gunakan bahan kasar atau pelarut. Pastikan petunjuk ujian bersih dan bebas daripada serpihan.

6.2 Penggantian Fius

The multimeter is equipped with fuse and diode protection. If the current measurement function stops working, the fuse may need replacement.

1. Pastikan multimeter dimatikan dan petunjuk ujian diputuskan.
2. Open the back cover of the multimeter (refer to battery installation).
3. Keluarkan fius lama dengan berhati-hati.
4. Replace with a fuse of the exact same type and rating (consult the device's internal markings or specifications for fuse type).
5. Tutup penutup belakang dengan selamat.
