APPLICATION NOTES
Finding Opens
'Opens' are dead-end conductors that are not connected to anything and
therefore do not pas current.
To find an open, use the T2200 transmitter, R2000 Receiver, and the
alligator clip cordset. See fig. 9 on page 12.
1. Verify that there is no voltage on the conductor you wish to trace.
2. Plug the two banana plugs into the T2200.
3. Connect the other alligator clip to a separate ground.
4. Connect the other alligator clip to the conductor.
5. Where possible, ground any other conductors sharing the same path
as the open wire.
6. Set mode switch to 'LOW'.
7. Turn the R2000 'On' by rotating the thumbwheel.
8. Switch to 'OPEN' mode and the x] sensitivity setting. Note: if the
conductor is buried in moist soil, the 'SHORT' mode will give better
results.
9. Move the R2000 down the wire a few feet and adjust the sensitivity
until 5 to 9 LED's are lit. Move the T2200's mode switch to 'MED' and
then 'HIGH' and leave it at the setting that causes the strongest
