Usage Notes
- Primary Use: Temperature measurement and control.
- Avoid excessive current that causes self-heating and measurement errors.
- When soldering with a soldering iron, maintain a distance of at least 2mm from the encapsulation head. Soldering temperature should be below 360, with a soldering time less than 3 seconds.
- Storage Temperature: -10 ~ 40.
- Storage Humidity: 75% RH.
- Avoid storage in environments with corrosive gases or direct light.
- After opening the package, reseal for storage. Shelf life is 1 year. Products exceeding the shelf life can be re-inspected according to the standard and can still be used if they meet the requirements.
- If using heat shrink tubing during processing, do not use a hairdryer for shrinking. Recommended method: place the product with heat shrink tubing into a constant temperature oven at 110 for 10-12 minutes.
