To determine whether the Ultrasonic U-V Cleaner is working properly, you can consider it from multiple aspects.
First, you can make a preliminary judgment by observing the indicator lights of the device. When working normally, the power indicator light should be on, indicating that the device is powered on. If the device has working status indicators, such as ultrasonic working indicators and ultraviolet working indicators, they should also light up accordingly during operation to indicate that the corresponding functions are running.
For the ultrasonic function, you can listen to the sound it makes when it is working. Under normal circumstances, a weak but continuous high-frequency vibration sound can be heard. If the sound is abnormally loud, noisy or completely silent, it may mean that there is a problem with the ultrasonic generator.
During the cleaning process, you can pay attention to changes in the surface of the cleaned items. If you are cleaning small items such as glasses and jewelry, a properly working ultrasonic wave should be able to gradually remove the dirt on the surface of the item and make the water turbid. If there is no obvious change in the dirt on the surface of the item after a period of cleaning, the cleaner may not be working properly.
For the ultraviolet function, you can use an ultraviolet detection card or a professional detection instrument. Place the detection tool within the irradiation range of the ultraviolet lamp. If the test results show that the ultraviolet intensity reaches a certain standard, it means that the ultraviolet function is normal.
In addition, you can also check the temperature of the device. During normal operation, the device may generate a certain degree of heat due to energy conversion, but if the temperature is too high or too low, it may indicate a fault.
Observe the control panel or display of the device. If there are relevant parameters displayed, such as working time, power, etc., make sure that these parameters are set and displayed normally.
At the same time, check whether the connecting parts of the device are stable and whether the wires are damaged or in poor contact.
For example, when using Ultrasonic U-V Cleaner to clean glasses, a properly functioning device can significantly reduce the oil on the glasses within a few minutes, the water becomes turbid, and a faint high-frequency vibration sound can be heard. If the dirt on the glasses is almost unchanged after cleaning, and the ultrasonic sound cannot be heard, then it is likely that the device has a fault.
For example, if the expected color change reaction does not appear on the card through the ultraviolet detection card, or the color change is very weak, it is necessary to consider whether the ultraviolet lamp is aged or damaged.
In summary, judging whether the Ultrasonic U-V Cleaner is working properly requires a combination of methods, including observing the indicator light, listening to the sound, checking the cleaning effect of the items, testing the ultraviolet intensity, paying attention to the device temperature and checking the connecting parts, etc. Through these methods, the working status of the device can be judged more accurately to ensure that it can perform cleaning work effectively.
