Recalibrating the device (if it has this feature) using a known standard like the salt test can often correct discrepancies. If still inaccurate, consider the age of the device; sensors can degrade over time.
• Display Not Working/Flickering: The most common cause is low battery. Replace the batteries with fresh ones. If the problem persists, try cleaning the battery contacts. Extreme temperatures or humidity can also temporarily affect LCD displays.
• No Power: Again, check or replace batteries. Ensure they are inserted correctly. If the device has an on/off switch, confirm it’s in the “on” position. For units with AC adapters, verify the power connection.
• Slow Response Time: If the readings update too slowly, it might be normal for your specific model, but ensure the device isn’t in an area with poor air circulation, which can delay accurate readings. Dust accumulation on the sensors could also be a factor; a gentle cleaning might help.
• Connectivity Issues (for smart models): If your Wi-Fi or Bluetooth model isn’t connecting, check your home network, device permissions in your app, and ensure the hygrometer is within range. Restarting both the hygrometer and your connected device (smartphone/router) can often resolve minor glitches.

If troubleshooting steps don’t resolve the issue, consult the manufacturer’s manual or customer support for further assistance.
