1. Introduction
Thank you for choosing the ERICKHILL EMF Meter RT-100 and Wood Moisture Meter EWM01. This combined device offers precise measurement capabilities for electromagnetic fields (EMF) and wood moisture content. The RT-100 is a 3-in-1 multifunctional meter designed to detect electric field (EF), magnetic field (MF), and radio frequency (RF) radiation. The EWM01 is a highly accurate wood moisture meter with a tricolor backlight for easy interpretation. This manual provides detailed instructions for the safe and effective use of both instruments.

4. Setup
4.1 Initial Charging (RT-100 EMF Meter)
The RT-100 EMF Meter has a built-in rechargeable battery. Before first use, or if the battery indicator shows low power, connect the meter to a standard USB power source using the provided Micro-USB cable. The charging indicator will show the charging status.
4.2 Battery Installation (EWM01 Wood Moisture Meter)
The EWM01 Wood Moisture Meter typically uses standard AAA batteries (not specified in product details, assume common type). Open the battery compartment, insert the batteries observing polarity, and close the compartment securely.
5. Operating Instructions
5.1 Operating the ERICKHILL EMF Meter RT-100
The RT-100 can measure electric field (EF), magnetic field (MF), and radio frequency (RF) radiation.
- Power On/Off: Press and hold the Power/Hold button for 2 seconds to turn the meter on or off.
- Measurement: Once powered on, the meter will automatically begin detecting EF, MF, and RF radiation. The values will be displayed on the LCD screen.
- Understanding Readings:
- EF (Electric Field): Measured in V/m.
- MF (Magnetic Field): Measured in mG (milligauss) or µT (microtesla). Use the UNIT button to switch.
- RF (Radio Frequency): The RF function can detect signals up to 10GHz, including 5G signals.
- Alarm Indication: If the detected radiation exceeds safe levels (e.g., more than 40V/m or 4µT/40mG), the screen will turn red, the indicator light will flash, and the buzzer will alarm.
- Hold Function: Short press the Power/Hold button to freeze the current reading on the display. Press again to release.
- Average/Peak Value: Press the AVG/VPP button to switch between average and peak value display modes.
- Buzzer Control: The AVG/VPP button also controls the buzzer sound.

5.2 Operating the ERICKHILL Wood Moisture Meter EWM01
The EWM01 is designed for accurate moisture content measurement in various materials.
- Power On/Off: Press the Power button to turn the meter on or off.
- Select Material Type: Press the Mode (M) button to cycle through the 7 calibrated scales for different material types. Ensure you select the correct scale for the material being tested to ensure accuracy.
- Taking Measurements: Carefully push the two metal probes into the material you wish to measure. Ensure both probes are fully inserted and making good contact. The moisture percentage will be displayed on the LCD.
- Interpreting Backlight: The EWM01 features a tricolor backlight to quickly indicate moisture levels:
- Green: Low moisture content.
- Orange: Moderate moisture content.
- Red: High moisture content.
- MAX Function: Press the MAX button to display the maximum moisture reading recorded during a measurement session.

6. Maintenance
- Cleaning: Use a soft, dry cloth to clean the exterior of both meters. Do not use abrasive cleaners or solvents.
- Storage: Store the meters in their original packaging or a protective case when not in use. Keep them in a dry environment, away from extreme temperatures and direct sunlight.
- Moisture Meter Probes: After each use, wipe the metal probes of the EWM01 clean to remove any residue. Ensure they are dry before storage to prevent corrosion.
- Battery Care: If the EWM01 will not be used for an extended period, remove the batteries to prevent leakage. For the RT-100, ensure it is charged periodically if stored for a long time.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| EMF Meter (RT-100) does not power on. | Low battery; Power button not pressed long enough. | Charge the meter using the Micro-USB port; Press and hold the Power button for 2 seconds. |
| EMF Meter readings are erratic or zero. | Interference from other devices; Meter not positioned correctly. | Move away from other electronic devices; Ensure the front sensing area is facing the source. |
