2. Tindakan Pencegahan Keamanan

2.1 Keamanan Listrik

Before connecting the power cord, verify that the supply voltage is AC 220 V ±10% and the frequency is 50 Hz or 60 Hz. You must use a three-prong outlet with a protective ground, and the protective ground resistance must be ≤4 Ω. Never cut or disconnect the protective ground wire, as doing so poses a risk of electric shock.

2.2 Keselamatan Lingkungan

Do not use in environments with flammable or explosive substances, strong electromagnetic interference, high temperatures and humidity, or excessive dust levels. Place the equipment on a level, stable surface, and ensure there is at least 0.5 m of operating space around it. Operating environment: temperature 15°C to 35°C, relative humidity 45% to 75%.

2.3 Prosedur Operasional

During testing, do not place your hands or any other part of your body within the pressure test area to prevent injuries from being crushed; test specimens must be securely fastened to prevent them from falling and causing safety incidents during testing; it is strictly prohibited to disassemble the equipment’s transmission mechanism or dismantle the machine without authorization.

5. Pressure Testing of Electrical Conduits

5.1 Persiapan

5.1.1 Persiapan Spesimen Uji

Cut a test specimen from the conduit with a length of (200±5) mm. Maintain the test environment temperature at (23±2) °C. Before the test, measure the outer diameter of the conduit specimen.

5.1.2 Determination of Pressure Values

Kode Klasifikasi	Catheter Types	Pressure N (tolerance ±4%)
1	Sangat ringan	125
2	Cahaya	320
3	Cina	750
4	Berat	1250
5	Kegemukan	4000

5.1.3 Positioning of Test Specimens and Equipment

Place the pipe specimen on the steel base, click “Up/Down” to move the steel block toward the pipe specimen. Stop just before contact is made, then click to reset the pressure reading to zero.

5.2 Pressure Test Procedures

5.2.1 Normal Test Procedure

Set the test duration to 60 seconds. Refer to Section 5.1.2, click the button for the desired pressure value to preset the pressure value and loading pulse, and then click “Start” to begin the test.

After the test begins, the steel block slowly applies pressure to the guide tube. When the pressure value begins to change, the timer starts counting the time from 0 until the preset pressure value is reached. When the current pressure value reaches the preset pressure value, the timer stops counting the time from 0 until the preset pressure value is reached, and the timer begins counting the current test duration.

When the current test duration reaches the preset test duration, the device sounds an alarm, but the current pressure value remains at the preset pressure value. According to the standard, after the test is complete, the outer diameter of the specimen at the flattened section must be measured without relieving the pressure. The difference between the original outer diameter and the outer diameter of the specimen after flattening must not exceed 25% of the original outer diameter measured before the test.

Click “Reset” to release the pressure and return the steel block to its initial position. After (60±2) seconds, measure the outer diameter of the flattened portion of the specimen again. The difference between the original outer diameter and the outer diameter of the flattened specimen must not exceed 10% of the outer diameter measured before the test.

After the test, the test specimen must not exhibit any cracks visible to the naked eye or with corrected vision without any additional magnification.

5.2.2 Debugging Load Pulses

Depending on the catheter’s compressive strength, the preset loading pulses may require adjustment. During normal testing, if the timer stops while the load is being applied from 0 to the preset pressure value and the duration is not within the range of (30±3) seconds, the number of loading pulses must be adjusted.

Taking 4000 N as an example, the corresponding preset number of loading pulses is 2700. If the actual loading duration is 25 seconds, which is less than the standard requirement of (30±3) seconds, you can change the number of loading pulses from 2700 to 2600 and try again; If the actual loading duration is 35 seconds—which exceeds the standard requirement of (30 ± 3) seconds—then try changing the number of loading pulses from 2700 to 2800. Continue adjusting until the loading duration meets the standard requirement.

6. Pemeliharaan dan Perawatan Peralatan Harian

6.1 Perawatan Harian Setelah Pemutusan Daya

At the end of each day’s testing, clean dust and specimen debris from the equipment surfaces, and keep the steel blocks and steel bases clean and free of debris; use a special touchscreen cleaning cloth to clean the touchscreen; check the pressure-applied steel blocks for deformation or displacement.

6.2 Perawatan Rutin Mingguan

Apply a small amount of special-purpose lubricating grease to the equipment’s drive lead screw to ensure smooth, jam-free operation.

6.3 Pemeliharaan Selama Penyimpanan Jangka Panjang

After the equipment has been powered off and routine maintenance has been completed, cover the entire unit with a dust cover and store it in a dry, well-ventilated warehouse; power it on for 30 minutes each month to prevent components from being damaged by moisture.

6.4 Persyaratan Interval Kalibrasi

Untuk memastikan akurasi pengukuran dan keandalan operasional peralatan, disarankan agar peralatan tersebut secara berkala dikirim ke laboratorium metrologi pihak ketiga yang berkualifikasi untuk kalibrasi. Interval kalibrasi yang disarankan adalah 12 bulan. Pengguna dapat menentukan interval kalibrasi spesifik berdasarkan frekuensi penggunaan, kondisi lingkungan, dan persyaratan sistem mutu.

7. Pemecahan Masalah dan Penyelesaian Masalah Umum

Gejala Kesalahan	Kemungkinan penyebab	Prosedur
Touchscreen lags; taps don’t register	Screen surface smudges causing interference, program crashes	Turn off the device, clean the screen, then restart it and try again.
No pressure reading is displayed for an extended period after the test starts	The specimen guide tube was not positioned beneath the steel block, and the steel block was too far from the specimen guide tube.	Reposition the specimen guide tube; use the down arrow key to move the steel block closer to the specimen guide tube, then try again.
The load time is not within the (30±3)s range.	Since catheters have different compressive strength, the preset loading pulses may need to be adjusted.	Follow the instructions in Section 5.2.2 for debugging.
Pressure Drift	After the equipment has been in use for a long time, it is important to calibrate the force readings.	We recommend having the equipment calibrated by a third-party metrology organization. You can adjust the pressure reading by accessing the calibration screen.
