How do I perform a basic survey using my survey meter?

How to Detect Background Radiation

To see what the background radiation is in your area, simply turn the instrument on and, after the 30 second start up beep, the general background radiation will be displayed.

 

How To Survey a Surface

When surveying a surface, such as a counter top, you will need to hold The Ranger about 1-2 centimeters from the surface while moving the unit horizontally across the survey area at a rate of 2 inches per second.

 

How to Perform a General Survey

A general survey would be used to find a potential source. For example, if you are looking for a potential source in a pile of scrap, The Ranger will typically detect about 2 feet into a pile. It is easier to find a source when The Ranger is set to Fast Response mode. However, even if The Ranger is in Auto-Averaging mode, the audio clicks that indicate a count should be a sufficient indicator if a potential source is present. To find the source, slowly move The Ranger in the direction of the higher readings or clicks until the potential source is found.
