故障排除

Possible cause

The batteries are completely discharged.

Solution

Charge the batteries.

可能原因

USB连接线损坏。

解决方案

更换USB连接线。

可能原因

外接电源电量放尽。

解决方案

给外接电源充电。

Possible cause

Calibration is required.

Solution

Carry out calibration according to Calibration Mode section.

解决方案

如果图像在校准后依然不清晰，需要重新校准。

可能原因

设备在运行期间暴露于静电中。

解决方案

设备在暴露于静电中后，可能会自动重启，或需要关闭后再开启。

可能原因

亮度或对比度太低。

解决方案

在快速菜单中调节亮度或对比度级别。

可能原因

可能会在恶劣天气条件（雪、雨、雾等）下出现所述问题。

Possible cause

Password in the device was changed.

Solution

Delete network and connect again inserting the password saved in the device.

Possible cause

There are too many Wi-Fi networks in the area where the device is located which may cause signal interference.

Solution

To ensure stable Wi-Fi performance, move the device to an area with few or no Wi-Fi networks.

Solution

Switch the device's Wi-Fi band.

Possible cause

The device has a 5 GHz network enabled, but the smartphone only supports 2.4 GHz.

Solution

Switch the device's Wi-Fi band to 2.4 GHz.

可能原因

透过玻璃观察。

解决方案

将玻璃从视野中移除。

Solution

The presence of such pixels is associated with the manufacturing technology of displays and microbolometer. It is not a defect.

可能原因

由于热导率的变化，被观察目标（周围环境、背景）在零上温度时变暖速度比较快，可提高温度对比度，因此，热成像仪生成图像的质量较高。

在工作温度低的情况下，被观察目标（背景）通常会降至大致相同温度，导致降低温度对比度，从而降低图像质量（精度）。这是属于热成像技术的原理，不属于设备质量问题。

Possible cause

There is an object in front of the receiver or emitter lens preventing signal transmission.

Solution

Make sure that: the lenses are not blocked by your hand or fingers; the lenses are clean.

Possible cause

The device is not being held steadily when measuring.

Solution

Keep the device steady when measuring.

Possible cause

Distance to the object exceeds 1000 m.

Solution

Pick an object at a distance not longer than 1000m.

Possible cause

Low reflection ratio (for example, tree leaves).

Solution

Pick an object with higher reflection ratio (see point Additional Information in section Laser Rangefinder.

可能原因

恶劣天气条件（雨、雾、雪）。
