5. Persediaan

5.1 Pemasangan Bateri

The UT201R requires two AAA batteries (not always included, check packaging). To install or replace batteries:

  1. Pastikan meter dimatikan dan tiada wayar ujian disambungkan.
  2. Locate the battery compartment cover on the back of the meter (refer to Figure 3.3).
  3. Gunakan pemutar skru untuk melonggarkan skru pada penutup bateri.
  4. Remove the cover and insert the batteries, observing correct polarity (+ and -).
  5. Pasang semula penutup bateri dan ketatkan skru.

Nota: Tanggalkan bateri jika meter tidak digunakan untuk tempoh yang lama bagi mengelakkan kebocoran.

5.2 Menghubungkan Petunjuk Ujian

Untuk voltage, resistance, continuity, diode, and frequency measurements, connect the test leads as follows:

Pastikan sambungan kukuh sebelum mengambil sebarang ukuran.

6. Arahan Operasi

Always ensure the meter is set to the correct function before making any measurement.

6.1 Pengukuran Arus AC

  1. Putar dail fungsi ke 40A~ or 400A~ kedudukan.
  2. Buka clamp rahang dengan menekan picu.
  3. Masukkan hanya satu konduktor litar dalam clamp rahang. Pastikan rahang ditutup sepenuhnya.
  4. Baca nilai semasa AC pada paparan LCD.

Nota: Jangan clamp multiple conductors simultaneously, as this will result in an inaccurate reading (the magnetic fields will cancel each other out).

6.2 AC/DC Jldtage Pengukuran

  1. Sambungkan petunjuk ujian seperti yang diterangkan dalam Bahagian 5.2.
  2. Putar dail fungsi ke V∼ (Jilid ACtage) atau V— (DC Voltage) position. If the dial position is shared, press the PILIH button to toggle between AC and DC.
  3. Connect the test probes in parallel to the circuit or component being measured.
  4. Baca voltagnilai e pada paparan LCD.

6.3 Pengukuran Rintangan

  1. Pastikan litar dinyahtenagakan sebelum mengukur rintangan.
  2. Sambungkan petunjuk ujian seperti yang diterangkan dalam Bahagian 5.2.
  3. Putar dail fungsi ke Ω position. Press PILIH if needed to choose resistance mode.
  4. Sambungkan kuar ujian merentasi komponen yang hendak diukur.
  5. Baca nilai rintangan pada paparan LCD.

6.4 Ujian Kesinambungan

  1. Pastikan litar dinyahtenagakan.
  2. Sambungkan petunjuk ujian seperti yang diterangkan dalam Bahagian 5.2.
  3. Putar dail fungsi ke Ω kedudukan dan tekan PILIH until the continuity symbol (♫) appears on the display.
  4. Sambungkan kuar ujian merentasi litar atau komponen.
  5. Jika kesinambungan wujud (rintangan di bawah ambang tertentu), meter akan mengeluarkan bunyi bip yang boleh didengar.

6.5 Ujian Diod

  1. Pastikan litar dinyahtenagakan.
  2. Sambungkan petunjuk ujian seperti yang diterangkan dalam Bahagian 5.2.
  3. Putar dail fungsi ke Ω kedudukan dan tekan PILIH until the diode symbol (▲) appears on the display.
  4. Sambungkan prob ujian merah ke anod dan prob ujian hitam ke katod diod.
  5. Paparan akan menunjukkan vol ke hadapantage drop. Balikkan kuar; bacaan litar terbuka menunjukkan diod yang baik.

6.6 Pengukuran Kekerapan

  1. Sambungkan petunjuk ujian seperti yang diterangkan dalam Bahagian 5.2.
  2. Putar dail fungsi ke Hz position (often shared with voltage atau semasa, gunakan PILIH sekiranya perlu).
  3. Connect the test probes in parallel to the circuit where frequency is to be measured.
  4. Read the frequency value in Hertz (Hz) on the LCD display.

6.7 Bukan Kenalan Voltage (NCV) Pengesanan

  1. Putar dail fungsi ke NCV kedudukan.
  2. Move the NCV sensor (located at the top of the clamp rahang) dekat dengan konduktor atau alur keluar.
  3. Sekiranya AC voltage is detected, the meter will emit an audible beep and the NCV indicator light will flash. The intensity of the beeping and flashing may increase with stronger fields.

Amaran: NCV detection is for indication only. Always verify voltage presence or absence with direct contact measurement before working on a circuit.

7. Penyelenggaraan

7.1 Pembersihan

Lap meter casing dengan iklanamp kain dan detergen lembut. Jangan gunakan bahan pelelas atau pelarut. Pastikan meter kering sepenuhnya sebelum digunakan.

7.2 Penggantian Bateri

When the low battery indicator appears on the display, replace the batteries as described in Section 5.1. Always use new batteries of the specified type.

7.3 Penentukuran

The UT201R is factory calibrated. For professional calibration services, contact UNI-T customer support or an authorized service center.

8. Penyelesaian masalah

If the meter does not function correctly, refer to the following common issues and solutions:

MasalahKemungkinan PuncaPenyelesaian
Tiada paparan atau paparan malapDead or low batteries; incorrect battery polarity.Replace batteries; check battery orientation.
Bacaan tidak tepatIncorrect function selected; poor test lead connection; external interference.Verify function dial position; ensure leads are firmly connected; move away from strong electromagnetic fields.
"OL" (Lebihan) dipaparkanInput value exceeds the meter's range.Select a higher range (if available) or ensure the measurement is within the meter's capabilities.
Tiada bip kesinambunganCircuit is open; continuity threshold not met.Check circuit for breaks; ensure resistance is below the meter's continuity threshold.

If the problem persists, contact UNI-T customer support.
