What is the role of the two adjustment knobs of the TV high voltage package?

The probe features a double-headed needle design, model 058-JJ-5.7L. Each end has a round needle with an outer diameter of 0.5 mm, making it ideal for precise applications.

Equipped with a single-chip microcontroller STM32L151CCU6, this device ensures efficient and stable performance, suitable for low-power applications.

The TV high voltage package includes two adjustment knobs. One is used to adjust the focus, while the other controls the brightness. It's important to note that the brightness adjustment affects the anode high voltage. Therefore, avoid increasing the brightness unnecessarily, as this can lead to higher levels of ultraviolet radiation, which may be harmful. Adjusting the knobs is straightforward. First, display some content on the screen, then turn the knob slowly and observe the changes in real-time. This allows you to fine-tune the settings based on visual feedback. After making the necessary adjustments, it's recommended to apply a small amount of candle oil into the gap of the knob shaft. This helps prevent the knob from loosening over time, ensuring long-term stability and usability.
