6. Prosedur Pasca-Ujian

6.1 Penghentian Tes

Jika EUT terlihat rusak selama pengujian, segera ketuk “Hentikan Pengujian” pada layar sentuh dan ketuk “Daya EUT” untuk mematikan daya EUT.

If no anomalies occur during the test, wait for the ringing tone test to end automatically, then click “EUT Power” to turn off the EUT.

Turn off the CDN input power supply switch built into the host.

Wait 5 minutes to ensure that the high-voltage capacitors inside the main unit have completely discharged, then replace the EUT for testing, or turn off the power to the main unit and the Isolation Transformer.

6.2 Post-Test Preparation and Cleanup

Clean up the test area and wipe it down with a dry cloth. Do not use alcohol or corrosive cleaning agents.

Ring wave testing is a destructive test; it does not automatically generate a test report, but the device automatically saves the test data. You can go to “System Information” to view and export the test log, which can be exported to a USB flash drive via the USB port. The exported file is in TXT text document format.

6.3 Penyimpanan Peralatan

6.3.1 Persyaratan Penyimpanan Jangka Pendek

Jika peralatan tersebut digunakan setiap hari, tidak diperlukan tindakan lebih lanjut setelah pembersihan selesai dilakukan setelah setiap pengujian.

6.3.2 Persyaratan Penyimpanan Jangka Panjang

Jika perangkat tidak akan digunakan dalam jangka waktu lama (lebih dari satu bulan), harap lepaskan semua kabel dan tutupi perangkat dengan penutup debu untuk mencegah penumpukan debu.

Perangkat ini sebaiknya dinyalakan sekali sebulan selama setengah jam saja untuk mencegah penuaan komponen listrik (seperti kapasitor dan kontaktor).

7. Pemecahan Masalah dan Penyelesaian Masalah Umum

7.1 Perangkat tidak mau menyala

Symptom: After turning on the power switch, the device shows no response (the indicator light does not come on, and the fan does not spin).

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

Solution: 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. We recommend using a voltage-stabilized, pure 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 13

The figure below shows the location of the MOV (metal-oxide varistor) inside the filtered power supply:

Gambar 14

7.2 Pemutus Sirkuit Terputus di Laboratorium

Symptom: When a ringing wave is output, the laboratory ground-fault circuit interrupter trips.

Kemungkinan penyebab: Transformator isolasi tidak terhubung.

Solution: Connect an Isolation Transformer. During ringing wave tests, large transient pulse currents are generated; if an Isolation Transformer is not connected, it may cause the laboratory’s ground-fault circuit interrupter to trip.

7.3 Restart Perangkat Otomatis

Gejala: Perangkat akan otomatis memulai ulang saat terjadi lonjakan daya.

Possible cause: The ground wire is not properly connected.

Solution: Connect the PGND grounding terminal on the back of the host to ground, and ensure that the grounding resistance is ≤4Ω. Otherwise, high voltage may not be safely dissipated, causing the device to automatically restart.

7.4 Uji Sudut Fase Lonjakan Gagal

Symptom: The synchronization phase angle was set, but the ringing test did not follow the corresponding phase angle.

Possible cause: The EUT power is not turned on.

Prosedur: EUT (Equipment Under Test) harus diberi daya oleh sumber AC, dan harus dinyalakan selama pengujian agar generator lonjakan daya dapat mendeteksi bentuk gelombang daya EUT dan melakukan uji lonjakan daya sesuai dengan sudut fasa yang telah ditetapkan.

7.5 Bentuk gelombang mengandung interferensi

Symptom: When using a CRO connected to an oscilloscope port to examine ringing and surge waveforms, some noise becomes visible upon magnifying the waveform.

Possible cause: The CRO port is designed for user convenience, allowing quick and easy access to waveform data, but it may generate a small amount of noise.

Procedure: If you need to obtain the actual output waveform of the surge generator, or if you wish to calibrate the device, use an oscilloscope and a high-voltage probe to directly inspect the waveform at the CDN output.
