 Temperature measurement can be started till 5~10 minutes after the boot when the
measurement accuracy has already been stabilized.
 When the thermal imaging module is calibrated, it clicks every few seconds, which
may be accompanied by a short-time video lag.
 During the whole calibration process, the center of the screen must be targeted at
the uncovered forehead or ears of the assisting person. Otherwise, the calibration
result may leave a large margin error.
 During the calibration process, the calibration assistant person needs to stand still
until the calibration is completed.
 If a large margin error of the temperature measurement occurs as a result of
maloperation during the calibration process, please re-execute the one-click
calibration or manual calibration procedure (see below).
4.2.4. Manual Calibration
The helmet is ready for temperature measurement after One-Click
calibration. However, manual calibration can be applied to adjust the
temperature parameters to get a higher accuracy. Manual calibration
requires the assistance of a second person of normal body temperature.
Step 1: Let the assisting person stand 1 meter from the thermal
imager and measure his forehead temperature with the thermal
imager;
Step 2: The temperature reading will rise as increasing the
temperature adjusting parameter (see the red frame below) and vice
versa. The temperature adjusting parameter should be within the
range of -10~+10.
Step 3: Click "save" to confirm the parameters.
