Usage Precautions
3.1 Product Use: Temperature measurement and control.
3.2 Measurement Accuracy: Avoid excessive current that causes self-heating and measurement errors.
3.3 Soldering: For soldering iron use, maintain a distance of at least 2mm from the encapsulated head. Soldering temperature should be below 360, and soldering time less than 3 seconds.
3.4 Storage Conditions: Storage temperature: -1040; Storage humidity: 75% RH.
3.5 Environmental Avoidance: Avoid storage in environments with corrosive gases or direct sunlight.
3.6 Shelf Life: After opening the package, reseal for storage. Shelf life is 1 year. Products exceeding the shelf life can be re-inspected according to this standard and may still be usable if they meet requirements.
3.7 Heat Shrink Tubing: If using heat shrink tubing during processing, do not use a hot air blower for shrinking. Recommended method: Place the product with the heat shrink tubing fitted into a constant temperature oven at 110 for 10-12 minutes.
