4. Persediaan

4.1 Pemasangan Bateri

The DMMW3 requires one CR2032 lithium-manganese dioxide battery for operation. The battery is typically included but may need to be installed before first use.

1. Cari petak bateri di belakang multimeter.
2. Gunakan pemutar skru kecil untuk membuka penutup petak bateri.
3. Masukkan bateri CR2032, pastikan kekutuban (+/-) yang betul seperti yang ditunjukkan di dalam petak.
4. Tutup penutup petak bateri dengan selamat.

4.2 Menghubungkan Petunjuk Ujian

Insert the red test lead into the positive (+) input jack and the black test lead into the common (COM) input jack. Ensure a secure connection.

5. Arahan Operasi

Turn the rotary switch to the desired function. The multimeter is auto-ranging for most functions, simplifying operation.

5.1 Mengukur Vol. AC/DCtage (V~ / V-)

1. Set the rotary switch to the V~ (AC Voltage) atau V- (Vol DCtage) kedudukan.
2. Sambungkan petunjuk ujian secara selari dengan litar atau komponen yang ingin anda ukur.
3. Baca voltagnilai e pada paparan.

5.2 Mengukur Rintangan (Ω)

1. Ensure power is OFF to the circuit.
2. Set the rotary switch to the Ω (Resistance) position.
3. Sambungkan petunjuk ujian merentasi komponen.
4. Baca nilai rintangan pada paparan.

5.3 Ujian Kesinambungan ())))

1. Ensure power is OFF to the circuit.
2. Set the rotary switch to the continuity position (often shared with resistance or diode).
3. Sambungkan petunjuk ujian merentasi litar atau komponen.
4. A continuous beep indicates a low resistance path (continuity).

5.4 Diode Test (→|)

1. Ensure power is OFF to the circuit.
2. Set the rotary switch to the diode test position (often shared with resistance or continuity).
3. Sambungkan wayar merah ke anod dan wayar hitam ke katod diod.
4. Volum hadapantage drop will be displayed. Reverse the leads; an open circuit (OL) should be displayed for a good diode.

5.5 Mengukur Kapasitansi (F)

1. Ensure power is OFF to the circuit and discharge the capacitor before testing.
2. Set the rotary switch to the F (Capacitance) position.
3. Sambungkan petunjuk ujian merentasi kapasitor.
4. Baca nilai kapasitans pada paparan.

5.6 Measuring Frequency (Hz) and Duty Cycle (%)

1. Set the rotary switch to the Hz/% position.
2. Connect the test leads in parallel to the signal source.
3. The display will show the frequency. Use the function button (if available) to toggle to duty cycle measurement.

5.7 Measuring AC/DC Current (A~ / A-)

Note: The input data does not specify current ranges or dedicated current input jacks beyond the main positive/common. For a pocket DMM, current measurement might be limited or require specific lead placement. Always refer to the device's markings.

1. Ensure power is OFF to the circuit.
2. Set the rotary switch to the A~ (AC Current) or A- (DC Current) position.
3. Pecahkan litar dan sambungkan multimeter secara bersiri dengan beban.
4. Guna kuasa pada litar.
5. Baca nilai semasa pada paparan.
6. Always disconnect power and remove the multimeter from the circuit before restoring normal operation.

6. Penyelenggaraan

6.1 Pembersihan

Lap kes dengan iklanamp kain dan detergen lembut. Jangan gunakan bahan pelelas atau pelarut. Pastikan terminal input bebas daripada kotoran dan lembapan.

6.2 Penggantian Bateri

When the low battery indicator appears on the display, replace the CR2032 battery promptly to ensure accurate measurements. Follow the steps outlined in Section 4.1.

6.3 Penyimpanan

If the multimeter is not used for an extended period, remove the battery to prevent leakage. Store the device in a cool, dry place, away from direct sunlight and extreme temperatures.

7. Penyelesaian masalah

• Tiada paparan atau paparan samar:
  • Periksa pemasangan bateri dan polariti.
  • Gantikan bateri CR2032.
• "OL" (Overload) displayed:
  • The measured value exceeds the selected range (if not auto-ranging) or the meter's maximum capability.
  • Ensure the correct function is selected for the measurement.
  • Untuk rintangan/kesinambungan/diod, pastikan litar dinyahdayakan.
• Bacaan tidak tepat:
  • Pastikan wayar ujian disambungkan dengan betul dan tidak rosak.
  • Periksa paras bateri; gantikan jika rendah.
  • Sahkan fungsi dan julat yang betul dipilih.
  • Ensure proper connection to the circuit under test.
