3. Setup
3.1. Charging the Device
The ERICKHILL ER02 EMF Meter comes with a built-in rechargeable Lithium-polymer battery. Before first use, or when the low battery indicator appears, charge the device using the provided USB charging cable. Connect the cable to the meter's charging port and to a standard USB power source (e.g., computer USB port, USB wall adapter).
3.2. Initial Power On
Press and hold the power button (usually labeled with a power symbol) to turn on the device. The LCD screen will light up, and the meter will enter its default measurement mode.
4. Operating Instructions
4.1. Power On/Off
- To Power On: Press and hold the HOLD button for approximately 2 seconds.
- To Power Off: Press and hold the HOLD button for approximately 2 seconds. The device also features an auto power-off function to conserve battery.
4.2. Measurement Modes (EF, MF, RF)
The ER02 can measure Electric Field (EF), Magnetic Field (MF), and Radio Frequency (RF) radiation. To switch between these modes:
- Press the MODE button to cycle through EF, MF, and RF measurement modes. The active mode will be indicated on the display (G. EF/MF/RF Testing Indicator).
Figure 5: 3-in-1 Measurement Capabilities
The ER02 provides distinct measurement ranges for RF, EF, and MF, with an effective range within 20cm of the source.
4.3. Unit Switching (for MF)
When in Magnetic Field (MF) mode, you can switch between milliGauss (mG) and microTesla (µT) units:
- Press the MG/UT button to toggle between mG and µT units.
4.4. Data Hold
To freeze the current reading on the display:
- Press the HOLD button briefly. The "HOLD" indicator (H) will appear on the screen.
- Press the HOLD button again to release the data hold and resume live measurements.
4.5. Alarm Function
The ER02 features an alarm that activates when measured values exceed predefined safety thresholds (0.4 µT (4 mG), 40 V/m, or 1 mW/m²).
- When the alarm is triggered, the buzzer will sound, and the display may change color or flash.
- To toggle the sound alarm on or off, press the SOUND button. This is useful in environments where an audible alarm might be disruptive.
4.6. Graph Mode
The ER02 offers a graph display mode to visualize changes in radiation levels over time.
- Short Press GRAPH: Switches between the standard measurement interface and the graph interface.
- Long Press GRAPH: Toggles the LCD display background between white and black for better visibility in different lighting conditions.
Figure 6: GRAPH Button Functionality
The GRAPH button allows switching between display modes and interface types for enhanced data visualization.
4.7. Average/Maximum Value
The meter can display either the average or the peak (maximum) value of the measurement.
- Press the AVG/MAX button to switch between displaying the average value (A) and the peak value (D). This is useful for observing fluctuations and identifying the highest radiation levels.

7. Troubleshooting
If you encounter issues with your ERICKHILL ER02 EMF Meter, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Low battery or no charge. | Charge the device using the USB cable. Ensure the charging cable and power source are functional. |
| Readings are erratic or unstable. | Interference from other electronic devices; user's body acting as an antenna; device too close to strong sources. | Move away from other electronics. Ensure proper distance from the source being measured (recommended within 20cm). Hold the device steadily. |
| Alarm sounds continuously. | Measured value exceeds the preset alarm threshold. | This indicates high radiation. Move away from the source or identify the source. Press the SOUND button to mute the alarm if desired. |
| Display is dim or unreadable. | Low battery; display brightness setting; environmental lighting. | Charge the device. Long press the GRAPH button to switch between white and black display backgrounds for better contrast. |
| Buttons are unresponsive. | Temporary software glitch. | Try restarting the device by powering it off and on again. If the issue persists, contact customer support. |
