The electronic clinical thermometer err is out of measurement range.

The core component of the electronic clinical thermometer is the NTC temperature sensor that senses temperature. The resolution of the sensor can reach ±0.01℃, the accuracy can reach ±0.02℃, the response speed is <2.8 seconds, and the annual resistance drift rate is ≤0.1% (equivalent to less than 0.025℃).

Temperature is one of the factors that affect the working performance of electronic products. Electronic products are different from ordinary products and have certain requirements on environmental conditions. Electronic devices have a normal operating temperature range. In order to prevent damage and erosion to electronic products, electronic products must Store, transport and use according to different environmental conditions.

The operating environment of the product is 10°C-40°C. If the environment is lower than 10°C or higher than 40°C during measurement, the product will display “Err” when the “Measure” button is pressed after the product is turned on. Therefore, the ambient temperature of the product needs to be It can be measured normally at 10℃-40℃.
