Key Features:
- 3-in-1 EMF Meter: Detects Electric Fields (EF), Magnetic Fields (MF), and Radio Frequency (RF) with a wideband coverage of 40 Hz to 10 GHz.
- 3-Axis X/Y/Z Sensors: Built-in sensors provide stable and reliable readings for magnetic fields, regardless of the device's orientation.
- Multi-Type RF Recognition: Identifies Wi-Fi/cellular (WiFi/PHONE), microwave (MICROWAVE), and mixed RF sources.
- Intelligent Alarm System: Features a tri-color LED and sound alarm (muteable) to indicate LOW, MEDIUM, or HIGH risk levels with dedicated thresholds for EF, MF, and RF.
- User-Friendly Design: Includes data hold, switchable units, ±5% accuracy, backlit screen, 15-minute auto-off function, and a USB rechargeable 1200mAh battery.


3. Package Contents
Verify that all items are present in the package:
- 1 x RDINSCOS EMF Meter (Model RD670)
- 1 x User Manual
- 1 x USB Charging Cable
4. Setup
4.1 Initial Charging
Before first use, fully charge the device using the provided USB charging cable. Connect the cable to the device's USB-C port and a standard USB power adapter (not included). The battery indicator on the screen will show charging status.

4.2 Powering On/Off
- To power on, press and hold the power button (⑂) until the screen illuminates.
- To power off, press and hold the power button until the screen turns off.
5. Operating Instructions
The RDINSCOS RD670 EMF Detector is designed for straightforward operation. Familiarize yourself with the buttons and display before use.
5.1 General Operation
- Mode Selection: The device automatically detects and displays EF, MF, and RF readings simultaneously.
- Unit Switching: Use the dedicated buttons to switch between units for Magnetic Field (mG/µT) and Radio Frequency (mW/m²/µW/cm²).
- Data Hold: Press the HOLD button to freeze the current readings on the screen. Press again to release.
- Backlight: Press the backlight button to toggle the screen backlight on or off.
- Auto-Off: The device features a 15-minute auto-off function to conserve battery. This can typically be disabled or enabled via a long press on the APO button.

5.2 Electric Field (EF) Detection
The EF mode measures electric field strength. Hold the device near electrical appliances, wiring, or power lines to detect their electric fields. Higher readings indicate stronger fields. The instrument identifies and displays 50Hz and 60Hz frequencies.


5.3 Magnetic Field (MF) Detection
The MF mode measures magnetic field strength. This is particularly useful for testing appliances, cables, and motors. The device features 3-axis (X/Y/Z) sensors, providing stable readings regardless of the device's orientation and displaying the radiation direction on screen.



5.4 Radio Frequency (RF) Detection
The RF mode measures radio frequency power density. Use this mode to detect signals from Wi-Fi routers, cellular devices (including 5G), smart meters, and microwave ovens. The device identifies and displays RF radiation source types as WiFi/PHONE, MICROWAVE, or MIXED.

6. Understanding Readings and Alarms
The RD670 features an intelligent alarm system with a tri-color LED indicator and an audible alarm (which can be muted). The alarm thresholds are pre-set to indicate different risk levels.
- Green Light: Indicates a LOW radiation risk.
- Orange Light: Indicates a MEDIUM radiation risk.
- Red Light: Indicates a HIGH radiation risk, accompanied by an audible alarm (if not muted).
Alarm Thresholds:
- Electric Field (EF): High Alarm Threshold: >500 V/m
- Magnetic Field (MF): High Alarm Threshold: >100 mG
- Radio Frequency (RF): High Alarm Threshold: >100 mW/m²



7. Maintenance
7.1 Cleaning
Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents, as these may damage the casing or screen.
7.2 Battery Care
The device contains a rechargeable 1200mAh Lithium Polymer battery. For optimal battery life, avoid fully discharging the battery frequently and store the device in a cool, dry place if not used for extended periods. Recharge using the provided USB cable.
8. Troubleshooting
8.1 Device Not Powering On
- Ensure the battery is charged. Connect the device to a USB power source and allow it to charge for at least 30 minutes before attempting to power on again.
- Verify that the power button is pressed and held correctly.
8.2 Inaccurate or Fluctuating Readings
- Ensure no other electronic devices are interfering with the measurement. Move away from strong magnetic or electric fields if testing for ambient levels.
- The device is designed for close-range detection. As distance from the source increases, field strength weakens, making long-distance measurements less reliable.
- Ensure the device is held steadily and not moved excessively during measurement.
8.3 No Sound from Alarm
- Check if the alarm sound is muted. Press the mute button to toggle the sound on/off.
- Ensure the detected radiation level exceeds the set alarm threshold for the respective field (EF, MF, or RF).
