Why are the readings unstable or inconsistent?

The readings may vary depending on the electromagnetic environment and how the device is positioned. We recommend holding the device steadily in one orientation (either vertical or horizontal) and avoiding sudden movements during measurement.

Why does the device sometimes display no value at all?

Ensure that the device you are testing is powered on and in operation. The detector measures electromagnetic fields generated during device operation. Environmental conditions with low EMF may also result in no readings.

Can this device measure RF signals like WiFi or mobile phone signal strength?

No, this device is designed to detect electromagnetic radiation fields (EMF), not radio frequency (RF) signals. It cannot measure signal strength from mobile phones, Wi-Fi routers, or cell towers.

How can I calibration the device?

For initial calibration, wave your hand briefly in front of the sensor and ensure the screen responds.

How can I confirm the device is functioning properly?

You can test it by holding it near an active device like a microwave or fan. When the device is powered on and operating, the detector will pick up EMF levels.
