1. Exceeding the maximum current in a hollow cathode lamp can cause excessive sputtering of the cathode material, leading to thermal evaporation or even melting of the cathode, which significantly reduces the lamp's lifespan. To ensure longevity, it is recommended to never exceed the specified maximum current during operation.
2. If the lamp has been stored for an extended period, it may not function properly due to potential gas leakage or internal contamination. It is advisable to ignite the lamp periodically, ideally every three months, to maintain its performance and prevent failure.
3. Prolonged use of the lamp can lead to aging, resulting in increased noise, unstable signals, and reduced light output. In such cases, reversing the activation process can help remove impurities and restore some of the lamp’s original performance. Regular maintenance is essential to avoid these issues.
4. After a lamp with a low melting point has been turned off, it should be allowed to cool completely before being removed from the lamp holder. This prevents damage caused by residual heat and ensures safe handling.
5. The light window of the lamp must remain clean at all times. If it becomes dirty, it should be gently wiped with high-quality lens paper to avoid scratching or damaging the surface. Keeping the window clear ensures optimal light transmission and accurate measurements.
6. Always check the power supply and connections before using the lamp to ensure stability and safety. Avoid exposing the lamp to extreme temperatures or humidity, as this can affect its performance and durability. Proper storage and handling are key to maintaining the lamp's efficiency over time.
