and vibration.
⚫
Heat dissipation space shall be reserved around the blackbody, and the
distance from the surrounding objects shall not be less than 10cm.
➢
Calibration
⚫
In order to ensure the accuracy of blackbody temperature measurement, it is
recommended to send blackbody to Dahua Co., Ltd. for paid calibration on a
regular basis. The calibration cycle is usually one year.
➢
Daily maintenance
⚫
The blackbody shall be managed and maintained by the designated personnel,
and the maintenance and use records shall be made.
⚫
In the process of use, it is not allowed to cover any object on the black body,
so as not to affect the heat dissipation and thus the temperature accuracy.
⚫
When it is unnecessary to use, dust prevention shall be done well, and the black
body shall be put into the packing box or covered with a clean cloth. Ensure
that the storage environment temperature and humidity are appropriate.
⚫
It is recommended to use neutral detergent to clean the blackbody shell and
soft brush to clean the dust on the radiation surface of blackbody.

Q
1. What is blackbody? What is the role? Do you need a physical connection to the
camera?
Blackbody can be simply understood as a constant temperature reference source
(constant temperature can be maintained after power on). When testing human body
temperature, blackbody is generally set at 35
℃
, which is used for temperature
correction of thermal imaging acquisition, so as to meet the accuracy requirements of
±
0.3
℃
.
Bold doesn't need to be connected to the camera, it's separate. After power on, it can
be placed in the camera screen according to the installation instructions.
2. Power on stabilization time of equipment.
