The ERICKHILL RT-100 is a portable, hand-held electromagnetic field (EMF) meter designed to detect and measure electric and magnetic field radiation simultaneously. This guide provides a comprehensive overview of how to operate the device, understand its readings, and maintain it for long-term use. Quick Setup & Basic Operation
The RT-100 is designed for one-handed operation and requires no complex configuration.
Power On/Off: Short press the power button to turn the meter on. To turn it off, long press the same button.
Measurement: Hold the device and slowly approach the radiation source (e.g., microwave, TV, or computer) with the top sensing area. Note: Avoid covering the top sensors with your hands, as this can interfere with the readings.
Auto-Shutoff: To conserve battery, the device automatically powers down after 5 minutes of inactivity. Understanding the Interface & Controls
The device features a backlit LCD screen that displays real-time data. Button/Action Function Description Short Press Power Locks the current reading on the screen (Data Hold). Short Press AVG/VPP Toggles between Average and Peak (Maximum) value modes. Long Press AVG/VPP Turns the audible buzzer alarm on or off. Short Press UNIT Switches the magnetic field unit between T (Microtesla) and mG (Milligauss). Alarm Thresholds & Safety Indicators
The RT-100 includes a built-in "Sound-Light Alarm." When radiation levels exceed safe thresholds, the screen turns red, the indicator light flashes, and a buzzer sounds. Electric Field (V/m): Alarm triggers at . Magnetic Field ($\mu > 0.4 \mu\textT > 4 \textmG$. Technical Specifications Electric Field (EF) Magnetic Field (MF) Range Resolution Bandwidth (Shared across both modes) Battery Lithium Battery (Rechargeable via USB) Common Applications
Home & Office: Testing low-frequency appliances like microwave ovens, refrigerators, printers, and computers.
Safety Inspections: Checking high-voltage cables and cell towers.
Ghost Hunting: Frequently used by enthusiasts for paranormal investigations due to its sensitivity to field changes. Troubleshooting & Maintenance ERICKHILL RT-100 EMF Meter
The Erickhill RT-100 is a handheld electromagnetic field (EMF) meter designed to measure electric field radiation and magnetic field emissions. You can download the official user manual directly from the Erickhill Manuals & Downloads page. Core Functions and Controls erickhill rt-100 user manual
Power On/Off: Short press the power button to turn the meter on. Measurement Modes: V/m: Measures the AC electric field. μT / mG: Measures the magnetic field.
Average vs. Peak: Short press the mode button to toggle between average and peak (maximum) value readings. Alarm System:
Thresholds: The device triggers a "Warning" when the electric field exceeds 40V/m or the magnetic field exceeds 0.4μT (4mG).
Alerts: When triggered, the screen turns red, the indicator flashes, and a buzzer alarms.
Silent Mode: Long press the buzzer button to turn the sound on or off for quiet testing.
Data Hold: Use the one-key hold function to freeze the current reading for easier viewing. Technical Specifications Specification Electric Field Range 1V/m – 1999V/m Magnetic Field Range 0.01μT – 99.99μT (0.1mG – 999.99mG) Measurement Bandwidth 5Hz – 3500MHz Sampling Time Approximately 0.4 seconds Display 3-1/2 digit backlit LCD Battery Built-in 3.7V rechargeable lithium battery Auto-Off Powers down after 5 minutes of inactivity Proper Usage and Maintenance
Testing: Hold the device near an active appliance (like a microwave or fan) to confirm it is picking up EMF levels.
Calibration: For an initial check, wave your hand in front of the sensor to ensure the screen responds.
Limitations: This model is designed for low-frequency electromagnetic radiation and cannot measure radio frequency (RF) signals like WiFi or mobile phone strength (the RT-100S 3-in-1 model is required for RF).
Cleaning: Wipe gently with a soft, dry cloth; do not use solvents or submerge in water. Device not turning on : check battery level,
Storage: Store in a cool, dry place and recharge periodically to maintain battery health. Manuals & Downloads - erickhill

is a dual-mode EMF meter designed to measure electric and magnetic fields simultaneously. While it is widely used for home safety and ghost hunting, its most interesting feature is its triple-threat alarm system that provides immediate, multi-sensory feedback. Most Interesting Feature: Triple-Threat Warning System
doesn't just show numbers; it uses three distinct methods to alert you when radiation levels exceed the "safe" threshold (40V/m for electric or 0.4µT / 4mG for magnetic fields):
Color-Coded Backlight: The LCD screen turns bright red for instant visual recognition of high levels.
Audible Buzzer: A continuous beep sounds, which can be muted for discrete "ghost hunting" or testing in quiet environments. follow these maintenance guidelines:
On-Screen Indicator: A specific "Warning" prompt appears on the display. Key Technical Features
The device is built for speed and ease of use, emphasizing one-handed operation:
Dual Mode Measurement: Displays both electric field (V/m) and magnetic field (mG/µT) readings at the same time.
Peak & Average Modes: Allows you to switch between real-time average readings and the "Peak" (maximum) value recorded during a session.
Rechargeable Battery: Unlike many budget meters, it uses a 3.7V lithium battery and includes a USB charging cable.
Wide Bandwidth: It monitors frequencies from 5Hz to 3500MHz, making it effective for low-frequency appliances like microwaves and refrigerators. User Resources
