29
3.Field use
After starting the machine, remove the lens cover, and start working after the system enters
the Infrared Acquisition interface. The operation method is as follows:
1) Parameter settings: adjust the temperature measurement parameters (emissivity, relative
humidity, distance and ambient temperature) according to the actual situation on site. Among
these parameters, the setting of emissivity is the most critical and has the greatest influence on
the temperature measurement accuracy.
Notes: ① The emissivity of power equipment is taken as 0.9 during general inspection. For accurate detection,
0.95 is taken for silicone rubber (including RTV and HTV), with 0.92 for electrical porcelain and 0.9 for oxidized
metal wires and metal connectors. Please refer to the Annex for the emissivity of more materials.
② When the shooting object is a metal surface capable of reflecting light (such as stainless steel), an insulating
tape (3M electrical insulating tape is recommended, black, emissivity: 0.93) may be attached to the surface of the
object for a period of time. After the temperature of the object is the same as that of the tape, the test will be
carried out, with the emissivity of the tape set to 0.93.
③ The temperature measurement range selected by the machine is -20℃~150℃ by default. If the temperature
of the target object is higher than 150℃, the medium temperature level must be selected manually or automatically.
2) Focusing: turn the manual focusing ring at the front end of the lens to make the measured
target in the clearest state in the image. Poor focusing will lead to a lower measured
temperature.
3) Temperature measurement: the temperature of the target object can be displayed in real
time by adding temperature analysis points/lines/frames in the infrared image of the target
object.
Note: when measuring temperatures, it is necessary to select the appropriate shooting distance. If the proportion
of the target in the whole image is too small, the accuracy of temperature measurement will be affected.

4) Data recording: keep the machine stable and press [Shoot] to save the infrared data to the
SD card
Note: If it is required to save visible light images at the same time, turn on "Save Infrared and Visible Light at
the Same Time" in "Other Settings".

5) When shooting an image, analyze the image again after it is frozen, with the method same
as that of "Secondary Analysis of File Viewing". refers to adding text annotations to an
image; refers to adding preset text annotations to an image; refers to adding audio
annotations to an image, refers to saving the current analysis information of an
image; refers to deleting the current image.
