6.Why do I get different temperature for continuous measurement? Sometimes in normal, sometimes in lower, sometimes in higher temperature.+
The user and thermometer need to adapt to ambient temperature. The rapid temperature change may cause the inaccurate measurement.
User
Before the measurement, please stay in a stable environment for 5 minutes and avoid exercise, bath for 30mins.
Thermometer
We recommend user to place thermometer indoor for 15 minutes to adapt to temperature and get the correct measurement. -
