Usage Precautions
- Purpose: Temperature measurement and control.
- Avoid excessive current that causes self-heating and measurement errors.
- When soldering, the joint should be at least 2mm away from the encapsulation head. Soldering temperature should be below 360, and soldering time less than 3 seconds.
- Storage Temperature: -1040.
- Storage Humidity: 75% RH.
- Avoid storage in environments with corrosive gases or direct sunlight.
- After opening the package, reseal and store. Shelf life is 1 year. Products exceeding the shelf life can be re-inspected according to the specified items; if they meet the requirements, they can still be used.
- If heat-shrinkable tubing is used during processing, do not use a hairdryer for heat shrinking. It is recommended to place the product with the heat-shrinkable tubing fitted into a constant temperature oven and heat shrink at 110 for 10-12 minutes.
