This manual introduces the use of the RF EMF strength meter.
The RF EMF Strength Meter Model 480836 is a broadband device designed to monitor high-frequency radiation in specific ranges of 900MHz, 1800MHz, and 2.7GHz, with reference measurements possible from 50MHz to 3.5GHz. It features a non-directional electric field sensor and three-channel digital processing for high dynamic range measurements.
You must replace the battery immediately.
Field strength increases proportionally to the inverse cube of the distance.
The smallest setting is 0.05V/m.
