Additional Notes
•
Sensitivity mode selection – general guidelines:
•
Start out at maximum sensitivity (SH/1 mode) until the receiver finds the circuit
under test. If the receiver is too sensitive, then reduce the sensitivity using the
button until the receiver’s display does not peg at "99" continuously.
•
Use Search High (SH/1) mode for tracing: (a) in closed circuits while using the
120VAC plug adapter (rather than the 25’ lead and a remote return path setup),
(b) in open circuits, (c) underground, (d) and anywhere else more signal
detection is needed.
•
Use Search Low (SL/2) mode to reduce the level of sensitivity if the Search High
mode has signal saturation (display is pegging at "99" continuously).
•
Use Trace (TR/3) mode for tracing (a) in closed circuits while using the 25’ lead
and a remote return path, (b) and when Search Low mode has signal saturation.
•
Use Breaker (BR/4) mode for (a) identifying circuit breakers and fuses, (b)
pinpointing individual wires from a bundle, (c) and when Trace mode has signal
saturation.

Receiver Orientation
•
The indication of received signal intensity depends on how the receiver is pointed
in relation to the source of the signal. If the receiver is pointed away from the
signal source then there will be a low value indicated on the receiver. If the
receiver is rotated about the axis of main antenna sensitivity, the signal varies in
strength as the antenna is pointed at and then away from the circuit being traced.
•
Therefore, rotate the receiver over the wire being traced until the highest reading
is displayed. If during tracing, the signal is reduced, the wire may have changed
directions (e.g. from horizontal travel across a wall to vertical travel up a wall).
Rotate the receiver to find the strongest signal again.
•
Use the back of the receiver to sweep the wall or floor and determine the circuit’s
general location. Use the nose of the receiver to pinpoint its location.
•
Steel conduit attenuates (weakens) the signal emitting from the wires inside the
conduit. Aluminum conduit significantly attenuates the signal. So, the receiver
should be set at a higher sensitivity and may need to be placed closer to the
circuit to obtain a stronger signal detection.
