Troubleshooting

Possible cause

The battery is completely discharged.

Solution

Charge the battery.

Solution

In case of any malfunctions during operation, try resetting the device by long pressing the ON/OFF button for 10 seconds.

Possible cause

The USB cable is damaged.

Solution

Replace the USB cable.

Possible cause

The external power supply is discharged.

Solution

Charge the external power supply (if necessary).

Possible cause

Calibration is required.

Solution

Perform image calibration according to the Microbolometer Calibration section of the manual.

Solution

If the image does not clear after calibration, you need to recalibrate.

Possible cause

After turning on the device, it takes some time for the sensor temperature to stabilize. This is normal and is not a defect.

Possible cause

Manual calibration has been performed with the lens cover open.

Solution

Check the Calibration Mode, close the lens cover and calibrate the device.

Possible cause

Brightness or contrast level is too low.

Solution

Adjust the brightness or contrast level in the Quick Menu.

Possible cause

The device was exposed to static charges during operation.

Solution

When the exposure to static charges is over, the device may either reboot automatically or require to be switched off and on again.

Possible cause

You are looking through glass.

Solution

Remove the glass or change the viewing position to avoid it.

Possible cause

These problems may occur during observation in adverse weather conditions (snow, rain, fog, etc.).

Possible cause

In positive temperature conditions, objects being observed (surroundings and background) heat up differently because of thermal conductivity, thereby generating a high temperature contrast. Consequently, the image quality produced by the thermal imager will be better.

In low-temperature conditions, objects being observed (background) will cool down to roughly the same temperature, which leads to a greatly reduced temperature contrast and a degraded image quality. This is normal for all thermal imaging devices.

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 (i.e. leaves of trees).

Solution

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

Possible cause

Inclement weather conditions (rain, mist, snow)
