• Vol. Bukan Kenalantage (NCV) detection with audible/visual alarm.

2. Maklumat Keselamatan

Always adhere to safety precautions when using the multimeter to prevent electric shock or personal injury. Read all safety information carefully before operation.

• jangan apply more than the rated voltage, seperti yang ditandakan pada meter, antara terminal atau antara mana-mana terminal dan tanah bumi.
• jangan use the meter if it appears damaged or if the case is open.
• Berhati-hati apabila bekerja dengan voltagadalah melebihi 30V AC RMS, puncak 42V atau 60V DC. Ini voltagia menimbulkan bahaya kejutan.
• Always ensure the test leads are in good condition, without any damage to the insulation.
• Putuskan sambungan wayar ujian daripada litar sebelum menukar fungsi atau julat.
• Gantikan bateri dengan segera apabila penunjuk bateri lemah muncul untuk memastikan bacaan yang tepat.
• Use the correct input terminals, function, and range for all measurements.

4. Persediaan

Pemasangan Bateri

1. Pastikan multimeter dimatikan dan petunjuk ujian diputuskan.
2. Cari petak bateri di belakang meter.
3. Buka penutup bateri dan tanggalkan.
4. Insert four 1.5V (R03) batteries, observing correct polarity.
5. Gantikan penutup bateri dan kencangkannya dengan skru.

Menghubungkan petunjuk ujian

Connect the red test lead to the VΩmA input jack and the black test lead to the COM input jack for most measurements. For high current measurements (up to 10A), connect the red test lead to the 10A input jack.

5. Arahan Operasi

The UT161B offers various measurement functions accessible via the rotary switch and function buttons.

Langkah Pengukuran Umum:

1. Putar suis putar kepada fungsi pengukuran yang dikehendaki.
2. Connect the test leads to the appropriate input jacks and to the circuit under test.
3. Baca nilai pengukuran pada paparan LCD.
4. Use function buttons (e.g., RANGE, HOLD, REL, MAX/MIN) for additional control or data capture.

Fungsi Khusus:

• VoltagPengukuran (AC/DC): Select V~ for AC voltage or V- for DC voltage. The meter can measure up to 1000V.
• Pengukuran Arus (AC/DC): Select A~ for AC current or A- for DC current. Ensure test leads are connected to the correct current input jacks (mA/µA or 10A).
• Pengukuran Rintangan (Ω): Select the Ω function.
• Pengukuran Kapasitans (F): Select the F function.
• Pengukuran Kekerapan (Hz): Select the Hz function.
• Diode/Continuity Test: Select the diode/continuity function. A buzzer will sound for continuity.
• Vol. Bukan Kenalantage (NCV): Use the NCV function to detect AC voltage without direct contact. The meter will provide audible and visual indications.

Komunikasi USB

The UT161B supports USB communication for connecting to a PC. This allows for real-time data monitoring, logging, and analysis using compatible software.

6. Penyelenggaraan

Pembersihan

Lap kes dengan iklanamp kain dan detergen lembut. Jangan gunakan bahan kasar atau pelarut. Pastikan terminal bebas daripada kotoran dan kelembapan.

Penggantian Bateri

When the low battery indicator appears on the display, replace the batteries as described in the Setup section. Always use the specified battery type (four 1.5V R03 batteries).

Penggantian Fius

If the current measurement function fails, the fuse may need replacement. Refer to the detailed fuse replacement instructions in the complete user manual for your specific model. Ensure to use a fuse with the correct rating to maintain safety and performance.

7. Penyelesaian masalah

• Tiada Paparan/Kuasa Hidup: Periksa pemasangan bateri dan pastikan bateri tidak habis. Gantikan jika perlu.
• Bacaan yang salah: Verify correct function and range selection. Ensure test leads are properly connected and not damaged. Check for low battery.
• Continuity Test Not Working: Ensure the circuit is de-energized. Check test leads for continuity.
• Kegagalan Pengukuran Semasa: Check if the fuse is blown. Replace with the correct type and rating if needed.
• NCV Tidak Mengesan: Ensure the NCV sensor is close to the AC voltage sumber.
