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
