Tone Generator

The Fault Mapper™ may also be used as a tone generator, to trace and identify cables and
wires. The user will need a «cable tone tracer».
Pressing the TRD/ button will inject a warbling (oscillating) tone into the cable or link
under test. When set, the following will be displayed:
* * * * * * * * * * * * * * * * * * *
Warble Tone
* * * * * * * * * * * * * * * * * * *
The injected signal oscillates between 810Hz and 1110Hz, six times per second.
NOTE: The auto-off function is disabled in Tone Generator mode, so that the tone can be
injected into a cable for an extended period of time while tracing takes place.
