3.2 Power On/Off
To power on the device, press and hold the Power button until the display illuminates. To power off, press and hold the Power button again.
4. Operating Instructions
4.1 Basic Measurement
Once powered on, the meter will immediately begin measuring electric (E-field) and magnetic (H-field) radiation. The values will be displayed on the LCD screen. For accurate readings, slowly approach the electromagnetic radiation source with the front sensing area of the meter. The effective and optimal measurement range is 0-30 cm.
4.2 Unit Switching
Press the UNIT button to switch between different measurement units:
- For Magnetic Field: mG (milligauss) or µT (microtesla).
- For Electric Field: V/m (volts per meter).
4.3 Average/Peak Value Reading
Press the AVG/VPP button to toggle between average (AVG) and peak value (VPP) readings. The AVG mode displays the average radiation level, while VPP mode shows the maximum (peak) value detected during the measurement period.
4.4 Data Hold
To freeze the current readings on the display, press the HOLD button. An 'H' icon will appear on the screen. Press the HOLD button again to exit data hold mode and resume real-time measurements. Ensure data hold is off when taking new measurements.
4.5 Sound-Light Alarm
The meter features a sound and light alarm. When the detected radiation level exceeds the preset safety thresholds (0.4 µT (4mG) for magnetic field or 40 V/m for electric field), the screen will turn red, the warning indicator will flash, and a buzzer will sound. To silence the buzzer, press and hold the Power button briefly. The visual alarm (red screen, flashing indicator) will remain active.
4.6 Backlight
The large LCD display is backlit for clear viewing in various lighting conditions.
4.7 Auto Power Off
The device will automatically power off after 5 minutes of inactivity to conserve battery life.
5. Applications
The ERICKHILL RT-100 EMF Meter can be used to test electromagnetic radiation from a variety of sources:
- Home Appliances: TVs, computers, printers, microwave ovens, refrigerators, air conditioners.
- Electronic Devices: Cell phones, laptops, power strips.
- Infrastructure: Cell towers, low-frequency home appliances.
- Other: Ghost hunting equipment.

6. Maintenance
- Keep the device clean and dry. Use a soft, damp cloth to wipe the exterior. Do not use abrasive cleaners or solvents.
- Avoid exposing the meter to extreme temperatures, humidity, or direct sunlight.
- Store the device in a safe place when not in use to prevent damage.
- Regularly charge the battery to maintain its performance.
7. Troubleshooting
7.1 Inaccurate Readings
- Ensure the front sensing area is slowly approaching the source within the 0-30 cm optimal range.
- Check if the HOLD function is active ('H' icon displayed). If so, deactivate it to get real-time readings.
- Verify that the correct units (mG/µT or V/m) are selected for the field you are measuring.
7.2 No Display/Device Not Turning On
- Ensure the battery is charged. Connect the device to a power source using the Type-C cable.
- Press and hold the Power button for a few seconds to ensure it's not just a short press.
7.3 Alarm Sounds Continuously
- Move away from the detected radiation source until the readings drop below the alarm thresholds.
- To temporarily silence the buzzer, briefly press and hold the Power button.
