Your excellent helper in cable test!

F. Pinpointing Drill Sites

Set up the 816T as described in and attach to the nearest

receptacle. Locate and mark the path of any signal near your drill site.

If you have reason to believe that other installations are present near

your drill site, use procedures outlined in Section 2C, Locating and

Tracking Buried Wires.

The signal generated by the transmitter can be detected through walls

and ceilings.

To pinpoint the transmitter's

location (specific point),

wrap the alligator clip

leads around the

transmitter, short the

leads together, turn

transmitter on and

secure it to the

opposite side of the

wall or ceiling with

tape. Scan the wall

with the antenna flat

against the wall. The peak

signal will be heard when the

antenna passes directly over the transmitter location.(Fig.06)
