Personal RF monitors are an important tool in the tower industry and play a pivotal role in helping workers protect themselves against RF emissions.
In order for a personal RF monitor to effectively warn workers of emissions that potentially exceed Safety Code 6 limits, however, the monitor must be functioning properly. Recognizing this, many workers perform what’s often described as a “sanity test” to ensure they’re monitor is functional.
The video posted below was developed by STAC to demonstrate how to use a standard push-to-talk radio to complete an RF monitor “bump test.” The bump test procedure detailed in this video can only be used to verify that a personal RF monitor is powered on and capable of detecting RF emissions. This procedure cannot be used to verify that the monitor is calibrated properly.

Personal RF Monitor “Bump Test” Instructions
Step #1 Power on the personal RF monitor and let it go through the self tests
Step #2 Hold down the transmitter button on a working push-to-talk radio (Note: Min. radio output requirement = ½ Watt ERP)
Step #3 Move the radio closer to the monitor until the first alarm goes off (Note: First alarm should sound when radio is approximately 2.5 – 5 cm away from the monitor)
Step #4 Continue moving the radio closer to the monitor until the second alarm goes off (Note: Second alarm should sound when radio is approximately 1 – 2.5 cm away from the monitor)
