FACT: The UV (ultraviolet) meter will detect the different ranges of ultraviolet rays from UV-A, UV-B, and UV-C. Ultraviolet rays are part of the light spectrum.
THEORY: In theory when a ghost/spirit manifests it will give off ultraviolet light, which can be detected by this meter.
HOW TO USE:
Check the weather for the day, paying close attention to the UV index. The UV index could have an effect on your readings.
Turn on the meter by holding down the button on the front of the meter.
Scan the area looking for any unusual readings.
At the end of the investigation make sure you log your readings in the log book.
RANGE: In the light spectrum the ultraviolet light ranges from 10nm to 400nm(nanometer). The 3 ranges of UV light are UV-A 320nm to 400nm, UV-B 280nm to 320nm, and UV-C below 280nm. The range on this meter is from 0 – 7+. The range from the meter to the active field depends on the strength of the UV source.
0 to 2 - Minimal
3 to 4 - Low
4 to 7 - Moderate
7 to 9 - High
10+ - Very High
READINGS: Normal activity through this meter occurs between 0 to 2 (no light), and 2 to 4 (safe). Paranormal activity occurs between 4 to 7 (caution). Any readings above 7+ (warning) is probably non paranormal.
