1. Membuka Kemasan dan Mengenal Peralatan Secara Dasar

1.1 Spesifikasi Teknis Utama

1.2 Pemeriksaan dan Verifikasi Aksesori Saat Membuka Kemasan

1.2.1 Membuka Kemasan dan Pemeriksaan Visual

When unpacking the device, handle it gently to avoid scratching the exterior casing with sharp tools. After unpacking, first inspect the exterior of the device to ensure there is no visible deformation or dents, and that the buttons are not damaged or loose. If you notice any abnormalities with the device or its accessories, do not turn it on. Please contact us immediately.

2 Tindakan Pencegahan Keamanan

2.1 Keamanan Listrik

2.1.1 Persyaratan Catu Daya

Gunakan stopkontak tiga cabang AC satu fasa 220 V ±10%, 50/60 Hz; cabang pembumian harus dihubungkan ke tanah.

2.1.2 Persyaratan Pembumian

Kabel ground instrumen terhubung dengan andal ke kabel ground pelindung, dan resistansi ground pelindung ≤4 Ω;

Do not short-circuit the output terminal to the AC power source to prevent the enclosure from becoming energized.

2.2 Keselamatan Lingkungan

2.2.1 Persyaratan Suhu dan Kelembaban

Avoid using the device in environments where humidity exceeds 70% (without condensation) or where temperatures fall outside the range of 0–35°C. The optimal operating temperature is 25 ± 2°C.

2.2.2 Kontraindikasi Lingkungan

Lingkungan dengan medan magnet yang kuat dan medan listrik yang kuat;

Lingkungan yang mengandung gas atau cairan korosif;

Areas with flammable and explosive dust, and locations containing hazardous materials;

Lingkungan dengan banyak debu, suhu dan kelembapan tinggi, serta sinar matahari langsung.

2.3 Keselamatan Operasional

During testing, the outer casing of the test object is electrically charged; do not touch it with your bare hands under any circumstances;

Spesimen uji harus diletakkan di atas alas isolasi karet;

Operator wajib mengenakan sarung tangan karet berinsulasi;

Operators must have dry hands and must not wear metal jewelry; eating or drinking is prohibited during testing to prevent accidents caused by electric shock;

Sebelum mengganti objek uji, Anda harus terlebih dahulu menghentikan pengujian dan melepaskan objek uji dari catu daya input;

When multiple people are involved, clearly define roles and responsibilities, and confirm them with one another before testing begins to avoid errors.

3. Pengoperasian Peralatan

3.1 Pengaturan Parameter

Prasyarat 3.1.1

To ensure operational safety, parameter settings cannot be made while the high-voltage rod and remote control cable are connected to the device. Please remove the high-voltage rod and remote control cable before configuring the parameters.

3.1.2 Setting Test Parameters in Automatic Mode

Note: Using GB/T 7000.1-2023 as an example, the following settings can be configured.

3.1.3 Introduction to Manual Mode

If the current test group is A, press the AM key to switch to Manual Mode A*. Manual Mode A* runs only the current test in test group A. If it is an IR test, press the SWITCH key to switch to ACW/DCW testing (provided that test group A is configured to perform ACW/DCW and IR tests simultaneously). Test parameters cannot be modified in manual mode; only the SWITCH and AM keys are available.

That is: In automatic mode, when a test is run, all test items configured in that test group are executed sequentially; in manual mode, when a test is run, only the current test item in that test group is executed.

3.2 Pengujian Operasional

3.2.1 Front Panel Overview and Wiring

Note: Once the remote control cable is plugged in, the Start and Stop buttons on the device’s front panel will be disabled.

3.2.2 Menghubungkan Objek Uji

Selubung benda uji harus bersih dan bebas dari minyak; letakkan di tengah alas isolasi, jauh dari permukaan logam benda kerja.

Taking a light fixture as an example, attach the grounding clamp to the fixture’s ground wire, and use the high-voltage tester to test the fixture’s power line (L or N).

Gambar 33

3.2.3 Uji Startup

Press the Start button or the control button on the high-voltage probe to start the test; press the Stop button or release the control button on the high-voltage probe to stop the test.

3.2.4 Viewing Test Results

If the test continues until it completes normally, it is considered passed. If any single test item fails, the test stops automatically, and the screen displays the failed test item. Please check whether the issue is due to the parameter settings or the test specimen itself.

4. Pemeliharaan dan Perawatan Peralatan Harian

4.1 Perawatan Rutin

Before powering on, inspect the equipment to ensure it is clean and free of damage, that the cables show no signs of aging or breakage, and that the connectors are secure; Check the grounding clamps for oxidation or burn marks; if present, wipe them with a specialized contact cleaner, and contact us to replace parts if necessary; after testing is complete, disconnect the power and wipe the equipment surface and test area with an anti-static, dry cloth.

4.2 Penyimpanan Jangka Panjang

Saat perangkat tidak digunakan dalam jangka waktu lama, simpan di tempat yang kering dan berventilasi baik, jauhkan dari kelembapan dan sinar matahari langsung; lepaskan semua kabel, simpan aksesori secara terpisah, dan tutupi perangkat dengan kain anti debu; nyalakan perangkat selama 30 menit setiap bulan untuk mencegah kerusakan komponen elektronik internal.
