4. Persiapan Sebelum Pengujian

4.1 Menghidupkan Peralatan

Plug the power cord into a standard three-prong outlet, press the power switch, and the instrument’s display will light up. The TE and NG indicator lights will both be off, and the leakage current and voltage displays will show 0. If there are no abnormal audible or visual alarms, this indicates that the device’s power-on self-test was successful. Use the AC/DC test mode selector switch on the main unit as needed.

4.2 Persiapan Spesimen Uji

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

5. Prosedur Uji

5.1 Pengaturan Parameter Uji

All parameter presets must be completed by following the steps below, with the high-voltage rod, remote control cable, and grounding clamps unplugged.

petunjuk	Note
①	Press the Set button; the numbers in the test time display window will flash. Set the test duration using the arrow keys and the value adjustment keys. If you need to manually control the test duration, set it to 0. Once set, press the Set button again to proceed to the next parameter. If you do not need to set any other parameters, press the Confirm button to exit.
②	Continue to set the next parameter. The number in the leakage current window will flash. Set the upper limit for the leakage current using the arrow keys, the decimal point key, and the value adjustment keys. Once set, press the “Set” key to proceed to the next parameter. If no other parameters need to be set, press the “Confirm” key to exit.
③	Continue to the next parameter to set the lower limit for leakage current. The factory default is 0, and this setting generally does not need to be adjusted. Press the “Set” button to proceed to the next parameter. If you do not need to set any other parameters, press the “Confirm” button to exit.
④	Continue to set the next parameter. The leakage current range automatically switches based on the upper limit value set for leakage current, with two ranges available: 2 mA and 20 mA. Press the “Set” button to proceed to the next parameter. If no other parameters need to be set, press the “Confirm” button to exit.
⑤	Continue to set the next parameter: buzzer alarm. “ON” enables it and “OFF” disables it; use the adjustment keys to toggle between settings. Once set, press the “Set” key to proceed to the next parameter. If you do not need to set any other parameters, press the “Confirm” key to exit.
⑥	Continue to configure the next parameter. The communication address and baud rate are communication-related parameters; since this device does not have communication capabilities, these do not need to be set. Screen brightness ranges from 1 (dimmest) to 5 (brightest). After configuring these settings, press the “Set” button to proceed to the next parameter. If no other parameters need to be set, press the “Confirm” button to exit.
⑦	Output Voltage Setting: Press the Start button and observe the value displayed in the output voltage display window. Use the output voltage adjustment knob to set it to the required standard value. Once adjusted, press the Reset button.

Catatan: Untuk pengujian dengan laju kenaikan tegangan yang ditentukan, jangan mengatur tegangan terlebih dahulu; cukup putar kenop ke 0. Setelah pengujian resmi dimulai, putar kenop secara perlahan untuk menyesuaikan tegangan keluaran ke tegangan uji pada laju yang ditentukan dalam standar.

5.2 Pengkabelan Peralatan

5.2.1 Pengkabelan untuk Uji Tegangan Tahan AC

petunjuk	Note
①	Insert the banana plug end of the grounding clamp into the instrument’s connector, and verify that the ground terminal or metal casing of the device under test is securely connected to the clamp’s grounding terminal.
②	Plug the remote control cable for the remote-controlled high-voltage rod securely into the remote control jack on the main unit.
③	Securely connect the high-voltage probe cable to the AC high-voltage output port on the main unit; keep the high-voltage probe’s output end away from the test object for the time being.

5.3 Uji Tegangan Tahan

5.3.1 Uji Startup

The output end of the high-voltage probe should make close contact with the charged parts of the test object (such as the power cord input or the winding leads). Then press the output control button on the high-voltage probe to perform the test.

5.3.2 Akhir Pengujian

Dalam mode pengatur waktu, ketika hitungan mundur berakhir, tegangan tinggi akan otomatis terputus dan pengujian berhenti; dalam mode manual, pengujian berhenti ketika Anda melepaskan tombol kontrol probe tegangan tinggi.

Jika terjadi salah satu dari kelainan berikut selama pengujian, pengujian harus segera dihentikan: asap, suara aneh, atau percikan api dari benda uji; suara aneh, bau aneh, atau layar hitam pada peralatan. Setelah penghentian darurat, selidiki penyebab kelainan tersebut; jangan melanjutkan pengujian sampai masalah teratasi.

5.4 Interpretasi Hasil Tes

Hasil pengujian dievaluasi terutama berdasarkan apakah terjadi kerusakan dan apakah arus bocor melebihi ambang batas.

5.4.1 Criteria for Acceptance

Throughout the entire test, the voltage remained stable at the required standard value, and the real-time leakage current remained below the set alarm threshold at all times; neither the “NG” indicator light nor the buzzer alarm was triggered.

5.4.2 Kriteria untuk Menentukan Ketidaksesuaian

Selama pengujian, jika arus bocor melebihi ambang batas alarm, indikator “NG” akan menyala dan bel akan berbunyi.

The test specimen exhibits obvious signs of breakdown, flashover, smoke, or other similar phenomena.

6. Pemeliharaan dan Perawatan Peralatan Harian

6.1 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 down the equipment surface and the test area with an antistatic, dry cloth.

6.2 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.
