Locate Passive Signal
Setup
Follow setup procedures for the type of locating you will be doing. Always check receiver battery level at
startup. See “Battery level” on page 21.
Technique
Survey the Site
Make a visual check of the site for signs of buried cables such as:
• recent trenching
• buried cable markers
• overhead lines that run down pole and underground
• gas meters
• valve sights
• drains or manhole covers
Sweep the Site
Search the site by walking a grid pattern while
holding receiver close to the ground.
Focus the Signal
Move receiver over detected signal to find best
signal response. If using a peak antenna
mode, rotate receiver until signal is best. Best
signal indicates cable direction.
NOTICE: Cables with no A/C current flowing through them are hard to detect and may be hazardous
because they may still have voltage potential. To locate, turn on an appliance to cause current to flow
and use active search methods.
NOTICE: Keep receiver vertical.
