Setup
Follow setup procedures for the type of locating you will be doing. Always check receiver battery level at
startup. See “Controls” on page 13.
Use 60P frequency to locate primary lines from source to transformer. Use 60S frequency to locate
secondary lines from transformer to meter.
Technique
Survey the Site
Make a visual check of the site for signs of buried lines such as:
• recent trenching
• buried line markers
• overhead lines that run down pole and underground
• gas meters
• valve sights
• drains or manhole covers
NOTICE: Lines with no AC 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.
