Advice
Temperature reading hampered
by hair or perspiration.
Make sure there is no obstructionor
dampness prior to taking temperature.
Temperature hampered by an air draft or dramatic
change in ambient temperature.
Make sure there is no air blowing in the area of use;
this could affect the infrared reading.
Temperature readings are too close together,
and the thermometer did not have time to reboot.
Pause for 3~5 seconds minimum between readings;
a 15 seconds pause is recommended.
The measuring distance is too far.
Take measurements at the recommended distance (app. °Cm~3cm).
