First use an infrared thermometer to measure the foreheads of yourself or colleagues (multiple people) for comparison, and then measure the same position of the tested person for multiple measurements. Note that the distance should be as consistent as possible, the recommended distance (25cm), and the location should be as consistent as possible. Here, you can first record your body temperature with a glass thermometer and keep it consistent with the infrared thermometer.
For example, when measuring the forehead, measure the forehead, not different parts. To measure the position exposed to the air, a hat or scarf needs to be removed for a while before taking the measurement.
If the temperature deviation is found to be large, use other temperature measuring equipment to confirm, such as glass thermometer, ear thermometer, etc.
Do not irradiate the eyes during use.
The measurement occasions should be kept as consistent as possible, such as outdoors, the first item should also be carried out outdoors.
