Simple Temperature Change Test Method: Place the thermometer in a refrigerator for about 1 hour, then take it out and check if there is a noticeable change in temperature. If there is a significant change, it indicates that the thermometer is working properly and can be used with confidence.

A simple method to test relative humidity: There are ventilation holes at the bottom of the product's back. First, check the current humidity indicator, then exhale several times directly into the ventilation holes. If the humidity gauge needle clearly rises, it indicates that the humidity gauge is working normally, so you can use it with confidence.
