What is 'dirty electricity' and why is it relevant to paranormal investigations?
Answer: High-frequency voltage spikes on power lines that create spurious EMF readings
Dirty electricity refers to high-frequency interference riding on standard power lines, which can produce false EMF spikes investigators may misidentify.
How does distance affect the strength of an EMF reading from a localized source?
Answer: It decreases with the square of the distance from the source
EMF intensity follows an inverse-square law, meaning doubling the distance reduces the field strength to one-quarter of its original value.
Which environmental condition can cause a non-contact infrared thermometer to give inaccurate temperature readings?
Answer: High ambient humidity reflecting IR energy
High humidity can absorb or scatter infrared energy, reducing the accuracy of non-contact IR thermometers.
What does a sudden localized cold spot detected by thermal imaging most likely indicate first to a skeptical investigator?
Answer: An HVAC draft, window air leak, or evaporative cooling effect
Before attributing a cold spot to paranormal causes, investigators must rule out mundane explanations such as drafts, leaks, or evaporation.
The K-II EMF meter uses a series of LED lights to indicate field strength. What color LEDs typically indicate the highest detected EMF level?
Answer: Red
The K-II meter's LED scale progresses from green (low) through yellow and orange to red, indicating the highest EMF levels.
Why is it important to document the GPS coordinates or precise room location when logging an EMF anomaly?
Answer: To allow repeat measurement at the exact location during follow-up investigations
Precise location documentation enables investigators to return to the exact spot for reproducibility testing on future visits.
Which feature distinguishes a single-axis EMF meter from a three-axis (isotropic) meter?
Answer: A single-axis meter must be rotated to find peak field strength, while a three-axis meter reads all directions simultaneously
Single-axis meters are directional and require manual rotation to find peak readings, whereas three-axis meters measure field magnitude in all directions at once.
