Power
Power frequencies refer to 50 or 60 Hz signals, and their harmonics that can
be traced without the use of a transmitter.
60H (high harmonic): Best for general locating of passive power.
60L (low harmonic): Secondary choice for passive power locating. May be
used when high harmonic is weak or erratic.
120 Hz: Used for locating rectified AC power signals, often found on
pipelines using impressed current cathodic protection.

Transmitter 2200) can be used to detect
some CATV cables (31.5 KHz).
(A horizontal-scan television NTSC must be turned on to generate this
frequency.)
