5. Gunakan perangkat eksternal untuk memverifikasi keluaran lonjakan arus.

5.1 Using an External Oscilloscope (Using the LISUN Osiloskop Seri OSP sebagai Contoh)

5.1.1 Menggunakan Port CRO

Set the following parameters on the Impulse Test Generator: Set the voltage to +1 kV; set the interval as short as possible, such as 5 seconds; and set the number of surges to a higher value to make it easier to view each waveform.

Do not connect any EUT; ensure that the circuit is completely open. Then, use the coaxial cable provided to connect the “CRO-V” port of the Impulse Test Generator to the oscilloscope.

Tekan tombol ① “Menu” di bawah ② “Pemicu.”

Gambar 25

① Pilih saluran yang terhubung, ② atur mode pemicu ke “Normal,” ③ klik untuk melanjutkan ke halaman berikutnya.

Gambar 26

① Pilih tepi naik.

Gambar 27

Tekan kenop CH1 (①).

Gambar 28

① Pilih pengali 1X; ② Matikan fungsi pengujian saat ini.

Gambar 29

The Impulse Test Generator has a built-in 1000:1 high-voltage Voltage Probe at the CRO interface. If the surge voltage is set to +1 kV, the actual voltage reaching the oscilloscope is 1 V. Turn the ① CH1 knob to set the ② vertical axis of the oscilloscope to 1/5 per division, or 200 mV, which makes it easier to view the entire waveform. Turn the ③ “Scale” knob to set the ④ horizontal time axis of the oscilloscope to 10 μs per division.

Gambar 30

Turn the two knobs—① (left/right) and ② (up/down)—to adjust the position of the waveform display to the appropriate location shown in the figure. Turn the ③ “Trigger” knob to adjust the level to approximately the middle position.

Gambar 31

On the touchscreen of the Impulse Test Generator, tap “Start” to begin the test. Each time a pulse is output, the oscilloscope will display a surge voltage waveform as shown in the figure below. Use the horizontal cursor to verify the output voltage; since it is set to 1 kV, the oscilloscope should display 1 V.

Gambar 32

Gunakan kursor vertikal untuk memastikan waktu setengah lebar gelombang.

Gambar 33

Atur skala waktu ke 1 μs, biarkan semua pengaturan lainnya tidak berubah. Tunggu keluaran lonjakan berikutnya, lalu gunakan kursor vertikal untuk menentukan waktu naik lonjakan tersebut.

Gambar 34

5.1.2 Connecting to the EUT Port

Connecting an external oscilloscope to the CRO port is intended solely for the user’s convenience when viewing waveforms. However, if the device needs to be calibrated, you must provide your own high-voltage probe and connect the oscilloscope directly to the EUT connection port on the front panel of the impulse withstand voltage tester. Refer to Section 5.1.1 and the scaling factor of the high-voltage probe being used when operating the oscilloscope.

5.2 Menggunakan Tabung Pembuangan

Tabung pelepasan dapat digunakan untuk memverifikasi dengan mudah apakah suatu perangkat menghasilkan lonjakan tegangan.

Connect the discharge tube to the pulse withstand voltage tester as the EUT. Set the output voltage to 12 kV, then click “Start” to begin the surge test. The discharge tube will flash the moment the pulse is output; please dim the lights in the room to facilitate observation. See the figure below:

Gambar 35

Ini memastikan bahwa perangkat memang menghasilkan lonjakan daya keluaran. Jika tabung pelepasan tidak berkedip, silakan hubungi layanan pelanggan.

6. Pemecahan Masalah dan Penyelesaian Masalah Umum

6.1 Perangkat tidak mau menyala

Gejala: Setelah menyalakan sakelar daya, perangkat tidak merespons (lampu indikator tidak menyala, dan kipas tidak berputar).

Kemungkinan penyebabnya: ① ​​Kabel daya tidak terhubung dengan benar atau rusak; ② Tegangan suplai tidak normal; ③ Sekring putus; ④ Varistor (MOV) terbakar.

Troubleshooting: Ensure the power cord is intact and securely connected. Power supply issues—such as unstable voltage, excessively high voltage, or harmonic interference—can cause the fuse or varistor to burn out. It is recommended to use a voltage-stabilized, clean sine-wave AC power supply to power the device. Replace the fuse or varistor with one of the same type.

Gambar di bawah ini menunjukkan lokasi sekering:

Gambar di bawah ini menunjukkan lokasi varistor (MOV) di dalam catu daya yang telah difilter:

Gambar 40

6.2 Restart Perangkat Otomatis

Symptom: The device automatically restarts during pulse output.

Possible cause: The ground wire is not properly connected.

Solusi: Lihat Bagian 2.2.1. Hubungkan terminal pentanahan PGND di bagian belakang host ke ground, dan pastikan resistansi pentanahan ≤4Ω; jika tidak, tegangan tinggi mungkin tidak dapat dibuang dengan aman, menyebabkan perangkat secara otomatis memulai ulang.

6.3 Bentuk gelombang mengandung interferensi

Symptom: When using an external oscilloscope connected to the CRO port to inspect a standard surge waveform, some noise appears when the waveform is magnified. See the figure below:

Gambar 41

Gambar 42

Kemungkinan penyebab: Osiloskop digital dan port CRO bawaan dirancang untuk memudahkan pengguna memperoleh data bentuk gelombang dengan cepat dan mudah, tetapi mungkin menghasilkan sedikit noise.

Procedure: If you need to obtain the actual output waveform of the surge generator, or if you wish to calibrate the equipment, use an oscilloscope and a high-voltage probe to directly inspect the waveform at the EUT connection port, as shown in the figure below:
