Installation & Use Precautions

• Application: Temperature measurement and control.
• Avoid excessive current that may cause self-heating and measurement errors.
• When soldering, maintain at least 2mm distance from the glass seal head. Soldering temperature should be below 360, and time less than 3 seconds.
• If leads are bent, the bending point should be more than 2mm from the glass shell to prevent damage.
• Storage Temperature: -1040.
• Storage Humidity: 75% RH.
• Avoid storage in environments with corrosive gases or direct illumination.
• After opening packaging, reseal for storage. Storage period is 1 year. Products exceeding the storage period can be re-tested against standard requirements and used if compliant.
• When using heat-shrink tubes, avoid using a hair dryer. Recommended method: place the product with the heat-shrink tube into a constant-temperature oven and heat shrink at 110 for 10-12 minutes.
