The ERICKHILL RT-100 is an electromagnetic field (EMF) detector primarily used for measuring electric and magnetic fields from household appliances and office equipment. You can download the official user manual directly from the ERICKHILL Manuals & Downloads page. Quick Start Guide
Power On/Off: Press the power button once to turn on the device. To turn it off, long-press the same button.
Taking Measurements: Hold the device and slowly approach the radiation source using the front sensing area.
Optimal Range: Keep the device within 0–30 cm of the source for the most accurate readings.
Constraint: Do not cover the top sensors with your hand or other objects while measuring.
Data Hold: Short-press the "H" or "HOLD" button to lock the current reading on the screen; press it again to resume live measurement.
Muting the Alarm: Long-press the "AVG/VPP" button to toggle the buzzer on or off. Technical Specifications & Features Measurement Types: Magnetic Field: Measured in milligauss (mG) or microtesla ( μTmu cap T Electric Field: Measured in volts per meter (
Alarm Thresholds: The screen turns red, and the buzzer sounds if readings exceed 0.4 μTmu cap T (4 mG) or 40 .
Power Management: The device features an Auto Power Off function that shuts the meter down after 5 minutes of inactivity.
Applications: Common uses include testing TVs, microwave ovens, refrigerators, cell towers, and equipment for ghost hunting. Important Troubleshooting
No Reading: If the meter shows no value, the radiation source may be below the detector's minimum threshold (e.g., less than
Unstable Readings: Hold the device steadily in one orientation (vertical or horizontal) to avoid fluctuations caused by sudden movement. erickhill rt-100 user manual
Calibration: For initial setup, you can perform a quick calibration by waving your hand briefly in front of the sensor to see if the screen responds. 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.
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

: Do not hold the meter in your hand or touch it with metal while taking measurements. Doing so can ground the device through your body and cause distorted high readings Distance Matters
: Since radiation drops off significantly with distance, move the meter closer or further from a source (like a microwave or electric meter) to find the peak radiation zone. Limited Spectrum
: This device is intended for AC mains wiring and low-frequency radiation; it does detect infrared light. Maintenance The device is often sold with a hard storage case to protect its sensors from physical damage.
