FAQ 3: When using the first time, I feel that the measurement temperature is deviated. What is the reason?


A: If it is for the first time, please follow the steps below:
Step 1: Place the thermometer in a stable ambient temperature for more than 30 minutes;
Step 2: Use a traditional mercury thermometer or an electronic thermometer to measure someone, assuming a temperature of 36.8 degrees Celsius;
Step 3: Use the non-contact infrared thermometer to measure the same person, pay attention to the measurement distance and measurement method: keep the distance between the thermometer and the forehead between 1-3 cm, remove any obstacles that may affect the measurement, If hair, sweat, etc., if you get the same temperature of 36.8 degrees Celsius, the thermometer is set up properly and can be used normally. If you get a lower reading of 36.4 degrees Celsius and the difference is 0.4 degrees Celsius, you can set F1 to "0.4 degrees Celsius". Conversely, if you are 0.4 degrees Celsius, you can set the F1 value to "-0.4 degrees Celsius".
