2. Măsuri de siguranță

2.1 Siguranța electrică

Before connecting the power cord, verify that the supply voltage is AC 220V ±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 Siguranța mediului

Do not use this equipment 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, leaving at least 0.5 m of operating space around it. Operating environment: temperature 5°C to 35°C, humidity ≤65% RH.

2.3 Proceduri de operare

During the test loading process, do not reach into the area of the clamps or the motor drive mechanism to prevent pinching injuries; test specimens must be securely clamped, as specimens falling out or weights dropping during the test may damage the equipment; it is strictly prohibited to disassemble the equipment’s drive mechanism or replace weights with non-original ones.

4. Wear Resistance Test for Plug Insulation Sleeves

4.1 Pregătirea probei

Select finished plugs that are intact, undamaged, and have not undergone aging tests. The test must be conducted on one prong of each test specimen.

4.2 Instalare și punere în funcțiune exemplu

Refer to the standard diagram in Section 3.1 to install the test specimen. Press the “Start Test” button to begin the test, observe the wire’s friction travel, and adjust the position of the connector so that approximately 7 mm of the 9 mm wire travel is covered by the insulating sleeve. Once adjusted, press the “Stop Test” button, then press the “Reset” button to clear the count.

4.3 Set Parameters and Start the Test

Instrucțiuni	notițe
①	Press the counter setting button, then use the up and down buttons and the directional buttons to change the number of settings; according to the standard, the number of tests must be set to 20000.
②	Press the Reset button to clear the current test data.
③	Press the “Start Test” button to begin the test.
④	During the test, observe the condition of the specimen and the steel wire. If any abnormalities are detected, press the “Stop Test” button, make the necessary adjustments, and then retry.
⑤	When the test is complete, the motor stops rotating; check the current test count to confirm that the test has been completed.

4.4 Evaluarea rezultatelor testelor

After testing, the plug should show no damage that could compromise safety or affect future use; in particular, the insulated sheath should not be worn through or wrinkled.

5. Întreținerea și îngrijirea periodică a echipamentelor

5.1 Întreținerea zilnică după oprire

At the end of each day’s testing, clean dust and specimen debris from the equipment surfaces, and keep the clamps and slide rails clean and free of debris; check the steel wire for looseness or deformation; if it is deformed or damaged, replace it.

5.2 Întreținere de rutină săptămânală

Apply a small amount of specialized lubricating grease to the equipment’s guide rails, drive screws, and bearings to ensure smooth, jam-free operation.

5.3 Întreținerea în timpul depozitării pe termen lung

After powering down and cleaning the equipment, apply rust-preventative oil to important components such as bearings, drive screws, clamps, and weights to prevent rust and deformation. Cover the entire unit with a dust cover and store it in a dry, well-ventilated warehouse. Power on the equipment for 30 minutes each month to prevent moisture damage to the components.

5.4 Cerințe privind intervalul de calibrare

To ensure the measurement accuracy and operational reliability of the equipment, it is recommended that it be sent periodically to a qualified third-party metrology laboratory for calibration. The recommended calibration interval is 12 months. Users may determine the specific calibration interval based on usage frequency, environmental conditions, and quality system requirements.

6. Depanarea și rezolvarea problemelor comune

Simptome de eroare	Cauze posibile	Procedură
The device did not respond after the test was started.	Loose power cord, blown fuse	Check the input power supply and power cord connections; check the fuse on the front panel of the device; if it is blown, replace it with a fuse of the same rating.
