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

- You don't receive any temperature measurement 
- Your temperature seems too high
- Your temperature seems too low
- Your back-to-back temperature measurements seem unstable

You don't receive any temperature measurement

Your temperature seems too high

• Make sure you follow the guidelines explaining 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: if you place it too far from your forehead, your Thermo could detect another hot spot.

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 temperature seems too low

• Make sure you follow the guidelines explaining how to take a measurement.
• Make sure the lens of your Thermo is clean.

The Thermo detects 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 detect the temporal artery. Therefore, the measured temperature may be too low.

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 takes several thousand measurements in 2 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 detect the temporal artery. Therefore, the measured temperature may be too low.

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.
