(2) Temperature measurement correction
With the temperature measurement correction function, you can adjust parameters in default mode. Or
you can add custom modes, change the mode name and parameters, then select modes you have
defined to quickly switch between different temperature measurement scenarios.
Difference between the default and custom modes: The default mode cannot be deleted and can restore
the preset temperature measurement parameters of the product. There can be up to 10 custom modes,
all of which can be deleted. By tapping a mode name, you can modify the name to one that consists of up
to 6 characters.
Emissivity correction: provides the surface emissivity of eight common objects and allows customized
object surfaces. 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 0.2m～5m. The recommended temperature measurement distance
is 0.25m. Other distances can be measured, but the accuracy of temperature measurement 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) Temperature unit
The temperature unit can be selected as Celsius (℃), Fahrenheit (℉), or Kelvin (K).
(4) Language settings

The app supports switching between Chinese and English. By default, it uses the same language as your
phone's operating system.
(5) Alarm settings
Above alarm: enter a threshold and save. The phone sounds an alarm when any temperature shown on
the image exceeds the threshold.
Below alarm: enter a threshold and save. The phone sounds an alarm when any temperature shown on
the image is lower than the threshold.
(6) Image optimization
This function is a noise reduction switch and can to some extend improve image quality. However, when
enabled, it consumes more power and may cause some phones with lower-level configurations to stuck.
This function is disabled by default. Decide whether to enable it as required.
3.2.4 Feedback
This is a channel for users to contact us.

The isotherm scale is used for palettes other than white-hot or black-hot to highlight the temperature zone
requiring special attention. The selected zone is displayed in the form of a palette while others are
white-hot. When the isotherm scale is in "M" status (see the upper and lower status indicators), adjust the
yellow slide on the left to select a temperature range to display in the form of a palette. When it is in "L"
status, the corresponding highest or lowest temperature is adjusted depending on the actual
temperatures in the image.
To clear all the spots, lines, and regions, tap the dustbin-shape control rightmost.

3.4 Dual-Spectrum
Dual-Spectrum enables the presence of a small window in the image display area to simultaneously
display the image taken by the phone camera. The small window supports drag operation.
To switch the front and rear camera of the phone, tap the reversal icon in the small window. The horizontal
flip of the infrared image is set in Personal Center -Setting - Image Flip.
3.5 Shutter Switch
If the infrared image has poor quality or displays obviously inaccurate temperatures, tap the shutter switch
to refresh the infrared imaging effect by turning on the shutter.
Under the preset conditions of the system, the device also automatically turns on the shutter to increase
the image quality.

Night Vision Go User Manual

3.6 Palette
By default, the app has white-hot, black-hot, and other palette modes. Select different palettes as you
prefer or as required. The palette mode does not affect temperature measurement. However, the isotherm
scale only applies to palettes other than white-hot and black-hot.
In addition, because colored infrared images are rendered, the data may be damaged after processing.
Therefore, the original white-hot image is the clearest.
3.7 Photo Taking
To take a photo of the display area and save it to the album, tap Photo Taking. The display area includes
the infrared image, visible-light image (dual-spectrum enabled), and temperature measurement elements
(temperature measurement enabled).

5.FAQs
(1) Q: Why does my Night Vision Go 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,Android 9.0 or later are recommended.
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 Night Vision Go app and granted all permissions required by the
app.
d) Unplug and plug in Night Vision Go. 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 Night Vision Go to observe objects under water, outside glass windows, under clothes,
or under the skin?
A: Night Vision Go 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.

Night Vision Go User Manual

(4) Q: Why is the measured body temperature not 36°C?
A: Different parts of the human body have different temperatures. Skins on the forehead, cheek, and
limbs are often exposed. Temperatures at these parts are largely affected by the ambient temperature,
ambient humidity, and the grease and sweat on skins. In normal cases, they will not be higher than 36°C.
For a person staying in a cool outdoor environment for a long time, a body temperature measured below
10°C is also normal. The temperature of skins exposed to the sunlight for some time is often higher than
36°C and can even reach 40°C.
(5) Q: Does Night Vision Go pose a radiological hazard to the human body?
A: Night Vision Go 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 need only to find abnormal heat sources, the distance attenuation does not affect the relative
temperature distribution. So they can use Night Vision Go 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 Personal Center - Setting - Temperature Measurement Correction - Distance
Correction.
