The Thermo takes several thousand measurements in two seconds to detect the hottest point of your forehead corresponding to your temporal artery. If the measurement gesture is not performed correctly, the Thermo won't be able to effectively detect the temporal artery. The end result is that the measured temperature may be too high, too low, or inconsistent across multiple readings.

This article will help you if you encounter any of the following issues:

- You don't receive any temperature measurement

- Your temperature seems inaccurate

- Your back-to-back temperature measurements seem inconsistent

Your temperature seems inaccurate

• Make sure you closely follow the guidelines on how to take a measurement.
• Make sure the lens of your Thermo is clean.
• Make sure your Thermo is placed close enough to your forehead; otherwise, your Thermo could detect another hot spot outside of the desired temporal artery area.

Note: The average temperature is between 36.5°C and 37.5°C (97.7°F and 99.5°F). The Thermo has an accuracy of +/- 0.2°C (0.4°F).

Your back-to-back temperature measurements seem unstable

The Thermo has an accuracy of +/- 0.2°C (0.4°F). It may be possible to notice temperature variations when taking back-to-back measurements.

We recommend you to take your temperature measurement on the same side of your forehead, because temperature can vary between the right and the left side.

Note: The different types of thermometers (temporal, rectal, oral, axillary) use different temperature measurement scales. They can each be used to follow the evolution of a person's temperature through time, but they should not be compared with one another.
