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