precautions
1. The armored thermoelectric corner used in this machine is an imported component, please use it in a standardized manner! Damage is not covered by warranty!
1) Please do not bend the fine wire sensor under any circumstances
2) When cleaning the residue on the top of the hot wire, please turn off the power switch, only gently scrape the top of the hot wire, and do not touch the fine wire temperature sensor.
2. The thermoelectric corner of this instrument is a high-precision component. Please do not pull it out at will when using it, and be careful when cleaning;
3. The temperature sensing element of this instrument operates at a high temperature, please do not touch it with your hands to prevent burns, and pay attention to safety when clamping and testing products;
4. During the experiment, please do not open the testing door to prevent toxic gases from affecting your health. After each experiment, please open the exhaust system for ventilation. Only after the harmful gases are completely discharged can the testing door be opened or the power supply be turned on or off;
5. After the experiment is completed, please clean the residue inside the instrument in a timely manner and clean the instrument to ensure its accuracy and service life;
6. Non professionals, please do not use the instrument at will to avoid accidents;
7. Keep the machine clean and tidy, and regularly spray anti rust oil to maintain the machine.
8. This machine uses a power supply of AC220V. Before connecting the power supply, confirm that the instrument casing is reliably grounded.
Features:
This test machine is used to evaluate the fire risk caused by thermal stress generated in a short period of time by heat sources such as glowing elements or overloaded resistors. It is widely applied in the fire hazard testing of electrical and electronic equipment and their components, as well as solid electrical insulation materials or other combustible solid materials.
**Specific application examples include:**
- **Testing of appliance housing materials**: Assessing whether the outer casings of TVs, microwave ovens, or electric kettles are prone to ignition due to internal component overheating.
- **Inspection of materials around circuit boards**: Determining whether insulating materials near circuit boards have sufficient flame-retardant performance during short circuits or overloads.
- **Evaluation of connectors and terminal blocks**: Testing whether surrounding plastic parts can ignite due to temperature rise caused by poor contact or current overload.
- **Safety verification of LED lamps**: Examining whether insulating materials near the driver module inside lamps meet thermal resistance and flame-retardant requirements under long-term operation.
- **Testing of automotive electronic components**: Such as on-board chargers and control modules, to verify whether the materials used meet fire safety standards under abnormal conditions.
This test machine is an essential tool for ensuring the safety design of electronic products.
