4. Pengantar Program Layar Sentuh

4.1 Layar Awal

Turn on the device and wait a moment. Once the program has finished loading, it will automatically open the initial screen: ① Switch between Chinese and English; ② Access the parameter settings screen; ③ Product information page.

Gambar 10

4.2 Antarmuka Pengaturan Parameter

① Discharge polarity setting; ② Discharge voltage setting; ③ Discharge mode selection: Contact Discharge or Air Discharge. This interface uses Contact Discharge as an example; ④ Trigger mode selection: Trigger mode can only be selected in Contact Discharge mode. In Air Discharge mode, according to standards, only the “Single” trigger mode can be used;⑤ Discharge count setting; ⑥ Discharge interval setting; ⑦ If automatic functions (automatic polarity switching, automatic voltage switching) are required, click here to configure them; ⑧ After clicking “Start,” the device will enter the charging state.

Gambar 11

Regarding trigger modes:
“Single” means one discharge occurs each time the trigger of the discharge gun is pulled;
“Repeat” means that after the trigger is pulled and released, the instrument enters an automatic repeat discharge mode and counts the number of discharges; once the set number of discharges is reached, it automatically exits the discharge mode. Pressing and releasing the trigger again during this period will pause the discharges; pressing and releasing it once more will resume discharges, and the count will continue.
“20PPS” refers to the 0.05-second rapid scan mode, which operates the same way as the “Repeat” mode, except that it automatically performs repeated discharges at 0.05-second intervals.

4.3 Automatic Function Interface

① Check the “Polarity Switching” box to automatically switch polarity during the test; ② Check the “Voltage Scan” box and enter the start voltage, end voltage, and step voltage in the input fields; the test will then run automatically according to the settings.

Gambar 12

4.4 Charging and Testing Interface

① Testing may only begin after charging is complete—that is, once 100% is displayed here—and the high-voltage indicator light on the front of the main unit illuminates; ② Once charging is complete, click “Trigger” or pull the trigger on the discharge gun to perform an electrostatic discharge test; ③ Click “Stop” to return to the parameter settings screen.

Gambar 13

Note 1: When the trigger mode is set to “single shot,” the interval between trigger pulls must be at least 1 second.

Note 2: When testing using the automatic function, the program will automatically return to the parameter settings screen when switching polarity or voltage, without requiring any manual intervention. It will then automatically proceed to the charging and testing screen. Only after the device has finished recharging can you click “Trigger” or pull the trigger on the discharge gun to continue the test.

Pegang pistol pelepasan dan posisikan ujung elektroda berbentuk kerucut secara vertikal terhadap titik uji konduktif EUT, pastikan kontak yang baik (tidak ada celah);

Pull the trigger of the discharge gun (single-shot mode) or pull and release the trigger once (continuous/20 PPS mode) to complete a single discharge or a continuous discharge;

Setelah menembakkan sejumlah peluru yang ditentukan pada setiap titik uji, pindahkan pistol penembak ke titik uji berikutnya dan ulangi pengujian;

Selama pengujian, amati status pengoperasian EUT secara real-time (misalnya, apakah tampilan berfungsi normal, apakah ada kesalahan yang dilaporkan, dan apakah ada fungsi yang terganggu), dan catat setiap anomali.

Note: In single-discharge mode, to simulate a single electrostatic discharge, the charge on the test equipment should be removed using an antistatic cloth before each electrostatic discharge pulse is applied.

6.2 Uji Pelepasan Udara (Uji Permukaan Isolasi/Soket EUT)

Hold the discharge gun and position the spherical electrode tip away from the EUT test point (at a distance of at least the voltage-corresponding distance—1 mm for 1 kV; for example, 15 kV requires a distance of at least 15 mm);

Pull the trigger of the discharge gun and hold it down, slowly moving toward the test point at an angle perpendicular to the EUT’s surface until a discharge spark occurs;

Immediately after the spark is generated, release the trigger and pull the discharge gun backward (to prevent multiple discharges), thereby completing a single air discharge;

After a 1-second interval, perform the next discharge test until the specified number of discharges is completed (10 discharges per point, 5 each for positive and negative polarities, or as required by the standard);

Selama pengujian, amati apakah EUT menunjukkan kelainan fungsional apa pun, dan catat lokasi titik pelepasan dan sifat kelainan tersebut.

Note: In single-discharge mode, to simulate a single electrostatic discharge, the charge on the device under test should be removed using an antistatic cloth before applying each electrostatic discharge pulse.
