Parameter Settings
To change the thermographic parameters (emissivity, RH, distance
and ambient temperature) according to the actual situations, among
which the emissivity is most important and has the biggest influence on
temperature measurement accuracy.
Note：
1 The emissivity is generally taken as 0.9 during patrol
inspection of electric equipment. For accurate inspection, the
emissivity can be taken as 0.95 for silicone rubber (incl. RTV and
HTV), 0.92 for electro ceramics, 0.9 for metal wires and metal
connections. Refer to the appendix for emissivity of more materials.
2 While the target is reflective metal surface (such as stainless
steel), you can put a piece of insulated rubber tape (3M electrical
insulating tape is recommended, black, emissivity:0.93) onto the target
surface, then wait a moment, and conduct the test after the target
temperature and the tape temperature becomes the same. The
emissivity should be taken as 0.93(the emissivity of the tape).
3
The default thermographic range is -20℃～150℃, so if the
target temperature is above 150℃, the thermographic range should be
changed to manual mode or auto medium.
Image Capture and Video Recording
You can pull the trigger to capture images in the image preview
interface, and you can also add annotations (such as words or voice)
to the images. Long press the trigger and the icon will appear on
the display area, which means recording, pull the trigger again to save
the video recordings into SD card.
Charging
The battery can be disassembled, the charging base can be used to
charge single battery or two batteries at the same time. The LED will
turn green, which indicates full battery capacity.
