cautions
- Use or store the product at specified operating or storage temperatures. Otherwise, the device may be damaged.
- Do not direct the product at high intensity thermal radiation sources, such as the sun, laser device, spot-welder, etc.
- Do not knock, toss, or shake the product and accessories.
- Do not place the battery in a high temperature environment or near high temperature objects. Do not short-circuit the positive and negative electrodes of the battery. Do not place the battery in a humid environment or water.
- Do not expose the device to dusty or damp environment. When used in an environment with water, avoid water splashing on the product.
- Do not use dissolved or similar liquids on the product or cables, as it may cause device damage.
- Please follow the following instructions when wiping the device:
Non-optical surface: If necessary, use a clean and soft cloth to wipe the non-optical surface of the thermal imager.
Optical surface: Do not stain the optical surface of the lens when using the thermal imager. Be especially careful not to touch the lens with hands, as sweat from hands will leave marks on the lens glass and may erode the optical coating layer on the glass surface. When the optical surface is stained, carefully wipe it with a special lens paper. - When using the device, please try to keep it stable and avoid violent shaking.
- Please close the lens cover and put the product and its accessories into the carrying box when it is not used.
- Please do not disassemble the device to avoid product damage and loss of warranty rights.
- Due to different batches, the materials and details of actual products may be slightly different from the graphic information. Please refer to the goods received.
- The experimental data in the manual are theoretical values and all from Uni-Trend’s internal laboratories, for reference only. Customers cannot use them as bases for placing orders. If users have any questions, please contact customer service.
- When the temperature is close to the scale switching critical point (about 150’C), due to the sensor’s own factors, the temperature measurement accuracy may exceed +/-2%, which is normal.
