4. Please do not measure with nail polish/fake nails/excessive
fingernails
5. Since dark-skinned people have a stronger ability to absorb infrared
rays, it takes longer to measure
6. The temperature will affect the measurement results. If the
temperature of the tested finger is too low, please rub the finger to warm
it up and measure again.

etc., infrared heaters, direct sunlight, etc.) will affect the measurement
results. Please cover appropriately or change the measurement
