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 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.

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 removed.

5.1.1 Selection of Leakage Current Range

Select the appropriate leakage current range button based on the standard requirements for the test item.

5.1.2 Mengatur Ambang Batas Alarm Arus Bocor

Switch the Preset/Test button to the preset state.

Slowly turn the current adjustment knob while observing the leakage current display window, and adjust the value to the alarm threshold specified in the test item’s standards.

Once the settings have been configured, switch the Preset/Test button to the Test mode; the leakage current display will return to 0, and the alarm value will be automatically saved.

5.1.3 Menentukan Durasi Tes

Pilih mode manual atau mode pengatur waktu sesuai dengan persyaratan standar pengujian:

Manual Mode: Flip the timer switch to the “On” position; there is no need to set a time—the operator manually controls the test duration.

Timer Mode: Press the timer switch to set the test duration to the required length (1–99 seconds); the time will be displayed as a countdown.

5.1.4 Pengaturan Tegangan Keluaran

Press the Start button and observe the value displayed in the output voltage display window. You can adjust it to the standard required value by turning the output voltage adjustment knob. 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

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	Colokkan kabel kendali jarak jauh untuk batang tegangan tinggi yang dikendalikan dari jarak jauh dengan aman ke soket kendali jarak jauh pada unit utama.
③	Securely connect the high-voltage probe cable to the AC high-voltage output port on the main unit, and 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

Place the output end of the high-voltage probe in close contact with the live 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 begin 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.

If any of the following abnormalities occur during testing, the test must be stopped immediately: smoke, unusual noises, or sparks from the test item; unusual noises, strange odors, or a black screen on the display. After an emergency stop, investigate the cause of the abnormality; do not resume testing until the problem has been resolved.

5.4 Evaluasi Hasil Tes

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

5.4.1 Kriteria Penerimaan

Throughout the entire test, the voltage remained stable at the standard requirement value, and the real-time leakage current remained below the set alarm threshold at all times; the “NG” indicator light and buzzer alarm were not triggered.

5.4.2 Kriteria untuk Menentukan Ketidaksesuaian

During testing, if the leakage current exceeds the alarm threshold, the “NG” light turns on and the buzzer sounds.

Spesimen uji menunjukkan tanda-tanda kerusakan yang jelas, lonjakan tegangan, asap, dan lain-lain.

6. Pemeliharaan dan Perawatan Peralatan Harian

6.1 Perawatan Rutin

Before turning on the equipment, check to ensure that the exterior is clean and undamaged, 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 a dry, antistatic cloth.

6.2 Penyimpanan Jangka Panjang

When the device is not in use for an extended period, store it in a dry, well-ventilated environment, away from moisture and direct sunlight; disconnect all cables, store accessories separately, and cover the device with a dust-proof cloth; turn the device on for 30 minutes once a month to prevent the internal electronic components from deteriorating.

7. Pemecahan Masalah dan Penyelesaian Masalah Umum

Gejala Kesalahan	Kemungkinan penyebab	Prosedur
Perangkat tidak mau menyala	The power cord isn’t plugged in securely; the fuse has blown.	Check the power cord connections; check the fuse in the device’s power input port; if it is blown, replace it with a fuse of the same type.
