Temperature measurement
-
Align the Detection lens1-5cm from the forehead
Note: holding the body for a long time may cause the detector to read higher ambient temperature, so the test result may be lower than the actual value. It is recommended to place the product in the normal temperature environment when not testing.
Please try to keep still during the test. -
Press the measurement button
The measurement will be completed within 1 second and a “Di” sound will be made after completing the test.
Check body temperature
Toggle the Change-over button and switch it to the left to set body temperature measurement mode. Lo characters is displayed when the measured value is below 32 ℃and three “Di” sounds will be made after completing the test.
The green color is displayed within the measured value of 32.0-37.2℃ and a
“Di” sounds will be made after completing the test.
The yellow color is displayed within the measured value of 37.3-37.9℃ and a
“Di” sounds will be made after completing the test.
The red color is displayed within the measured value of 38.0-42.5℃ and continuous “Di”alarm sounds will be made after completing the test. HI characters is displayed within the measured value above 42.5 ℃ and three “Di”alarm sounds will be made after completing the test.
Check Object surface temperature
Toggle the left and right switching button and switch it to the right to set surface object temperature measurement mode, and point the probe at the object surface then press the measurement button to measure the object surface temperature. The measurement will be completed within 1 second and a “Di”sound will be made after the test.

℃. Otherwise, it can not be measured correctly and there is a risk of injury
ATTENTIONS
Do not disassemble, repair or modify the body. It may cause errors in the
measurement results or machine failure|
---|---
The body is not waterproof. Use with care to prevent liquids (alcohol, water
or hot water) from entering the body. When the body is wet due to contact with
steam, please wait until it dries or wipe it gently with a soft dry cloth. It
may cause errors in the measurement results or machine failure.|
If there is a temperature difference between the body storage place and the
place where you want to measure, please put the body Stay in the room where
you want to measure for more than 30 minutes so that it reaches room
temperature first,Then measure. Otherwise, the measurement result may be low.
If the forehead is cold, wait until the forehead is warm before taking a
temperature measurement. If you use ice bags or ice packs, or when you enter
