HRI, or High Resistance Indicator, is a message displayed by some vape devices when the resistance of the coil is too high for the device’s settings. This safety feature prevents potential damage to the device and ensures a consistent vaping experience. This article explains what HRI means, why it occurs, and how to resolve it.

What Does HRI Mean?

HRI indicates that the resistance of the coil exceeds the recommended range for the device. Resistance, measured in ohms, determines how much power the coil needs to vaporise e-liquid effectively. High resistance can result in:

• Insufficient vapour production.

• Weak or muted flavour.

• Device errors or malfunction.

Common Causes of High Resistance

• Old or Damaged Coils: Coils wear out over time, and their resistance can increase as residue builds up.

• Improper Coil Installation: Loose or misaligned coils may cause the device to read resistance incorrectly.

• Incompatible Coils: Using a coil not designed for your device can result in resistance that is too high.

• Poor Connections: Dirt or debris on the device’s contacts can interfere with resistance readings.

How to Fix HRI Issues

• Check the Coil: Inspect the coil for signs of wear or damage. Replace it if necessary.

• Ensure Proper Installation: Remove the coil and reinsert it securely, ensuring it’s properly aligned with the tank or pod.

• Clean the Contacts: Use a cotton swab to gently clean the connections between the coil and the device.

• Use Compatible Coils: Verify that the coil you’re using matches the device’s specifications, particularly the recommended resistance range.

• Adjust Settings: If your device has adjustable wattage or voltage, ensure it’s set within the recommended range for the coil.

When to Seek Professional Help

If you’ve tried these steps and the HRI message persists, the issue may lie with the device itself. Contact the manufacturer or visit a reputable vape shop for further assistance.

Conclusion

HRI in vapes is a protective feature that alerts users to high coil resistance, ensuring safety and optimal performance. By understanding the causes and solutions, you can quickly resolve HRI issues and enjoy a better vaping experience. Regular maintenance and using compatible components are key to avoiding resistance-related problems.
