The accuracy of an infrared thermometer can be checked using a comparator at any stable temperature. However, to reduce the possibility of a difference in temperature between the inside surface and the base test hole, it is more accurate at 22°C, ambient room temperature.
Then, can forehead thermometers be inaccurate?
Drawbacks. Forehead thermometers must be positioned accurately and according to the manufacturer’s instructions, or they will not provide the right reading. Readings can be affected by external factors, including drafts, wind, indoor heating, and direct sunlight.
Similarly one may ask, how do I fix the LO on my infrared thermometer?
The ‘Lo’ or ‘Hi’ indications on the display mean that the temperature cannot be measured because the temperature is outside the temperature range. Press the on/off button to switch off the thermometer. Check if it is correctly positioned, press the on/off button again to switch it on, and re-start the measurement.

What is considered low temperature?
Body temperature below 95°F (35°C) is considered abnormally low, and the condition is known as hypothermia. This happens when your body loses heat faster than it can produce heat. Hypothermia is a medical emergency, which if left untreated can lead to brain damage and cardiac failure.
What is normal body temperature on forehead?
If you tell your doctor about your temperature reading, be sure to say where it was taken: on the forehead or in the mouth, rectum, armpit, or ear. Normal: The average normal temperature is 98.6°F (37°C).
