1. Ear Thermometer: What to do if it keeps flashing
Some ear thermometers may experience continuous flashing on the screen when in use. If the ear thermometer fails to function normally, displaying a constant flashing on the screen, several reasons may contribute to this issue:
The ear thermometer may struggle to function correctly if exposed to excessive fluctuations in ambient temperature when taken out, affecting both storage and testing environments.
The machine might display a full-screen flicker if the temperature falls below the minimum measurement environment requirements, preventing inaccurate measurements and data.
Another possibility is a problem with the battery. Here are several solutions to address the flashing of the ear thermometer:
Remove the battery, let the device stand for 20-30 minutes, ensuring the ambient temperature is above the minimum measurement temperature before turning it on.
Replace the battery, ensuring it is not of too high voltage. Choose a suitable battery according to the manual’s requirements.
Adjust indoor temperature by using air conditioning or measuring in a bed.
If the issue persists, consult the manual’s fault description page and check the displayed fault code on the screen. If unresolved, consider sending it to the factory for warranty service.
2. How to carry out daily maintenance of the ear thermometer
Proper maintenance of the ear thermometer is essential for its longevity and accuracy:
Clean the ear thermometer regularly using a soft cloth or a plastic-safe cleaner for the shell. Avoid using benzene-based solvent chemicals. Additionally, wipe and disinfect the probe with alcohol before and after use.
Store the ear thermometer in a cool place when not in use, avoiding exposure to sunlight. Use a protective box for storage, ensuring the temperature in the storage area is not too low.
The ear thermometer is not waterproof, so avoid exposing it to water or other liquids. When testing the temperature of beverages, such as boiled water or milk, do not submerge the probe. Instead, aim the pipette tip at the outside of the container for measurement.
3. Infrared Ear Thermometer: Accuracy compared to Mercury Thermometer
The accuracy of the infrared ear thermometer and the mercury thermometer is compared:
The mercury thermometer operates based on the thermal expansion ratio of mercury and temperature. It uses the stable nature of sealed mercury in a glass tube with a constant thermal expansion coefficient to measure body temperature.
The ear thermometer uses the intensity of infrared radiation energy emitted by the eardrum to convert it into body temperature, displaying the result on the screen.
While the mercury thermometer shows slightly higher accuracy, typically differing by 0.1-0.2°C, due to its longer measurement time, the ear thermometer is more suitable for home temperature monitoring. In situations requiring precise body temperature measurement, such as in hospitals, mercury thermometers remain a better choice.
