7.3 Tracing cables and wires indoors
7.3.1 Live and neutral electric cables
To connect transmitter to live targets, always use proper contact proof safety
class cords and adapters and follow safety instructions.
WARNING! If either transmitter output terminal is
connected to a live target as shown in the figure,
dangerous voltage appears on wires connected to
the other output as well, unless they are properly
grounded.
Task: The route of a live or neutral cable must be traced from a short
distance, e.g. inside walls or on cable shelves.
-
Connect transmitter to the Schuko wall socket neutral (N) and protective earth
(PE) contacts (not to phase contact) with
S3TB
cord’s corresponding wires.
-
Same method applies to situations where cable is disconnected or a fuse has
been blown.
-
Choose Near cable mode with receiver. Trace the cable route by following the
signal maximum. Right above the cable there is often a signal minimum.
Task: The route of a live or neutral cable must be traced from a longer
distance, e.g. near roof or on cable shelves which can’t be reached.
-
Connect one transmitter output terminal to a neutral wire of the cable and the
second output terminal to a good grounding, preferably using a ground pick for
best earth connection.
-
Choose
Cable route
mode with receiver.
-
Trace the cable route by following the signal minimum in the receiver nose
direction. This method usually enables tracing up to two metres distance. Closer
to the cable it’s possible to use
Near cable mode with receiver as well.
-
If cable’s wires are disconnected at the other end, signal gets weaker along the
path with
Cable route
mode. In that case it is recommendable to change to
Near cable mode and close range tracing. Closer to the end, signal minimum
gradually disappears and there is only a signal maximum above the right cable.
