Then, how do I know if my infrared thermometer is accurate?
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.
Beside this, how do you change Celsius into Fahrenheit?
To convert temperatures in degrees Celsius to Fahrenheit, multiply by 1.8 (or 9/5) and add 32.
How do you fix an infrared thermometer error?
Error 5~9, for all other error messages it is necessary to reset the thermometer.

How do you recalibrate an infrared thermometer?
Short of using a black body, the next best way to calibrate your infrared thermometer is to use a simple, inexpensive Infrared Comparator Cup. It is best to calibrate your infrared thermometer at more than one temperature (at 41°F [5°C] and 140°F [60°C] for example) and the Infrared Comparator Cup makes it easy.
How do you reset a no touch infrared thermometer?
To reset the unit, remove the batteries, wait 2 minutes and then re-install the batteries.
What does Lo mean on a thermometer?
The “Lo” or “Hi” indications on the display mean that the temperature cannot be measured because the temperature is outside the temperature range.
What is normal temperature for adults on forehead?
While typically 98.6°F (37.0°C) is considered a “normal” temperature, some studies have shown that “normal” body temperature can be within a wide range, from 97°F (36.1°C) to 99°F (37.2°C). Before NCITs are used, it is important to understand the benefits, limitations, and proper use of these thermometers.
Why is my digital thermometer not working?
Replace the battery
Use an insulated probe to remove the battery (e.g. a toothpick) Insert a new battery (LR41) with the + pole facing upwards. Reattach the battery compartment cover. Dispose of the empty battery in the proper way.
Why is my forehead thermometer reading low?
Low cost forehead thermometers may have such poor optics the thermometer may have to be almost touching the forehead to get reliable readings.
