Usage Precautions
- Product Purpose: Temperature measurement and control.
- Avoid excessive current causing self-heating and measurement errors.
- When soldering with an iron, the soldering point should be at least 2mm from the film. 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 and direct sunlight.
- Reseal packaging after opening and store. Shelf life is 1 year. After the shelf life, re-inspection according to the standard items can be performed; if requirements are met, it can still be used.
- If heat shrink tubing is used during processing, do not use a heat gun for shrinking. It is recommended to place the product with heat shrink tubing into a constant temperature oven and shrink at 110 for 10-12 minutes.
