2. OPERATION

A. Transmitter Connection

To locate non-energized cable, Push transmitter switch to

Cable Scan

.

There are two options for connection. You can connect one lead of the 

transmitter to the cable and the other lead to grounded earth or you can 

connect one conductor with grounded earth of a non-shielded drop wire. 

You can also connect two conductors to non-shielded drop wire.

B. Locating & Tracking Buried Wires

 

To locate buried electrical wires, CATV coax, telephone drops, irrigation 

control wires or metallic pipes, Push transmitter switch to

Cable Scan

 

attach one alligator clip lead of the 816T to an independent grounded 

earth  with a grounding stake or screwdriver. Do not connect to common 

ground such as a metal water pipe or the pedestal ground as they can 

cause cancellation of the reflected signal or produce false locating 

signals. Theother lead is attached to the cable or metallic pipe in the 

following manner:  

1. Non-energized Electrical Wires: Attach alligator clip lead to wires. 

2. CATV Coax: Attach lead to the shield. This aviods signal disruption. 

3. Telephone Drops: Attach controller lead to sheath. This aviods signal 

disruption. 

4. Irrigation Controller Wires: Attach lead to common wire or station wire. 

5. Gas Pipes with Pilot Wire: Attach lead to pilot wire. 

6. Metallic Pipes: Attach lead to pipe. 

Once the transmitter is attached to the cable, turn thumb wheel switch to 

high tone. swing the receiver antenna close to the ground and approxim

-ately ten to fifteen feet away from the transmitter location. The tone will 

be heard on either side of the path with a null (absence of tone) directly 

over the path. Proceed along the path following the“null”. direction adjust 

the transmitter and receiver controls to achieve further distances.
