• This device is for informational purposes and general environmental screening; it is not a substitute for professional-grade laboratory equipment or medical advice.

3. Product Features

• 3-in-1 Measurement: Simultaneously detects Magnetic Fields (MF), Electric Fields (EF), and Radio Frequency (RF) radiation.
• Multi-Color Backlight Display: The screen changes color (Green, Orange, Red) to visually indicate radiation levels, making it easy to interpret.
• Sound Alarm: An audible alarm activates when radiation levels exceed preset safe thresholds.
• Real-Time Trend Graph: Displays radiation changes over time, helping to identify peak exposures and hot spots.
• Data Hold & Peak/Max Measurement: Allows users to freeze current readings or view the highest recorded values.
• Rechargeable Battery: Equipped with a built-in Lithium Polymer battery, rechargeable via a standard USB Type-C port.
• Automatic Power Off: Conserves battery life by automatically shutting down after 15 minutes of inactivity.

5. Operating Instructions

5.1 Power On/Off

• Power On: Press the Power Button () located on the left side of the device. The display will light up.
• Power Off: Press and hold the Power Button for a few seconds until the display turns off. The device also features an automatic power-off function after 15 minutes of inactivity.

5.2 Measurement Modes

The KEMF-1 simultaneously measures Electric Field (EF), Magnetic Field (MF), and Radio Frequency (RF) radiation. The primary displayed value can be cycled using the FUNC button.

• Electric Field (EF): Measures electric field strength in V/m. Common sources include laptops, power lines, and electrical appliances.
• Magnetic Field (MF): Measures magnetic field strength in µT or mG. Common sources include microwave ovens, washing machines, and refrigerators.
• Radio Frequency (RF): Measures radio frequency power density in mW/m². Common sources include Wi-Fi routers, cell phones, and other wireless devices.

5.3 Display and Alarms

The device features a clear, multi-color backlit display. The backlight color changes based on the detected radiation level:

• Green: Safe levels.
• Orange: Elevated levels (caution).
• Red: High levels (danger).

An audible alarm will sound when radiation levels exceed the orange or red thresholds. You can toggle the sound alarm on or off by short pressing the Sound Alarm Button ().
