The target temperature range corresponding to high image quality is -20°C~120°C, and the target temperature range
corresponding to wide range is 20°C~550°C. The image of the high image quality mode is clearer than that of the wide
range mode, and the temperature measuring range of the wide range mode is wider than that of the high image quality mode.
Automatic switching is to automatically switch to high image quality or wide range according to the temperature of objects
on the screen.
3.3.4 Environmental Variable Correction
In the environmental variable correction function, users can choose to adjust the parameters in the default mode, and
select the emissivity according to the material of the target object in the use scene. With this function, you can add custom
modes, change the mode name and parameters, and select modes you have defined to quickly switch between different
radiometric scenarios for temperature measurement demand.
Difference between default mode and custom mode: The default mode cannot be deleted and can be restored to the
preset temperature measurement parameters of the product;
Emissivity correction: provides the surface emissivity of eight common objects and allows customized object surfaces.

12
The allowed emissivity range is 0.01～1.00.
Distance correction: corrects temperature measurement based on the input distance to the measured object. The
allowed distance range is 0.25m～5m. For a distance greater than 5m, select 5m, but the measurement accuracy cannot be
guaranteed.
Ambient temperature correction: corrects temperature based on the input ambient temperature of the current device.
The allowed ambient temperature range is the temperature range supported by the device.
3.3.5 Temperature Display
The temperature display function is only available in simple mode. Tap Temperature Display, and a cross icon will
appear in the center of the screen, and the highest temperature, lowest temperature and center point temperature of the

5. FAQs
(1) Q: Why does my P2 Pro not respond after being plugged into the phone?
A: Troubleshoot in this order:
a) Ensure that your phone runs with Android 6.0 or later
b) Verify that the OTG option is available on your phone and is enabled. If you are using OPPO, VIVO, OnePlus,
Realme, or iQOO, search "OTG" in Settings and manually turn it on. This function is automatically turned off after
10 minutes of inactivity. On most other phones, OTG is turned on by default and can be used directly.
c) Ensure that you have downloaded the P2 Pro app and granted all permissions required by the app.
d) Unplug and plug in P2 Pro. If it still does not respond, contact our after-sales staff.
(2) Q: What should I do in the event of a blurry screen or inaccurate temperature measurement?
A: Given the operating characteristics of uncooled infrared detectors, you need to refresh the screen using the
shutter, that is, tapping the shutter icon in the upper right corner. This helps produce clearer images and more
accurate temperatures.
(3) Q: Can I use P2 Pro to observe objects under water, outside glass windows, under clothes, or under the skin?
A: P2 Pro mainly detects an infrared wavelength range of 8~14μm. So it cannot observe through water or ordinary
glass and can only measure temperatures on the surfaces of clothes and skin.
(4) Q: How should I select the "temperature measurement mode"?
A: When the temperature of your target object is less than 120°C, or you have high requirements for image quality,
it is recommended to use the high image quality mode. When the temperature of your target object is greater than
120°C and less than 550°C, it is recommended to use the wide range mode. The automatic switching mode is to
intelligently select the temperature measurement mode of "high image quality and wide range" according to the
temperature distribution in the temperature measurement screen. The product is in high image quality mode by
default, and mode switching requires a period of time. Users can select the temperature measurement mode
according to his/her actual situation.
(5) Q: Does P2 Pro pose a radiological hazard to the human body?
A: P2 Pro does not actively emit any hazardous radiation but only collects the heat information of objects. It can be
used with peace of mind.
(6) Q: The temperature readings of people at a distance are relatively lower and can get higher when I come close to them.
Why is this happening?
A: The infrared radiation attenuates after passing through the atmosphere. The farther the distance is, the more it
attenuates. As a result, the temperatures measured are less accurate for objects at a distance. For users who only
need to find abnormal heat sources, the distance attenuation does not affect the relative temperature distribution. So
they can use the product as usual. Users who need accurate temperature data can obtain the corrected temperature
by inputting the distance from the object to be measured (up to 5m) in Temperature Measurement Correction -
Distance Correction.
