FAQ
Q: Why does the device often make a “clicking” sound while the screen freezes?
A: This is a normal occurrence caused by the infrared camera automatically hitting the shutter. During the imaging process, the absorbed scattered infrared light forms an abnormal heat source, causing the image to slowly become blurred. In such cases, refreshing the shutter can make the picture clear, but will produce a “clicking” sound. The shutter is set to refresh automatically every 30 seconds by default. If you mind the clicks, you can turn off the automatic shutter in the Settings.
Q: Can the device detect objects underwater, through glass or a wall?
A: No. Infrared detectors mainly detect 8 to 14 μm long-wave infrared areas, and can only be used to measure surface temperature.
Q: Why is there a lower temperature reading when the device gets far from the object and a higher reading when the device gets closer to the object?
A: Infrared radiation attenuates when passing through the atmosphere. The longer the distance, the greater the attenuation. Thus, the accuracy of temperature measurement at a distance will decrease. To ensure accuracy of measurement, go to Setting > Measure Parameter > Distance, and input the actual distance (max: 5 meters) to get the corrected temperature.
Q: Why is the measured temperature not very precise?
A: The temperature resolution of this device is ±2%, with a normal temperature range of -4 to 302°F (-20 to 150°C), and a high temperature range of -4 to 842°F (-20 to 450°C).Please select the corresponding range in the Settings before measuring.
Q: What external factors will affect the infrared temperature measurement?The following factors
A: The following factors will have an impact on the measurement results: a) Emissivity of the object surface. b) Ambient temperature: The object will reflect the infrared rays emitted by surrounding objects, which affects the temperature measurement of the object itself. c) Atmospheric temperature: The atmosphere itself also emits infrar.
