The .82 .kHz .reading .indicates .that .the .82 .kHz .frequency .is .in .use . .This .frequency .is .the .higher .
of .the .four . .The .82 .kHz .frequency .is .often .used .to .locate .highly .resistive .cables .or .pipes .and .
is .capable .of .jumping .disconnected .shield .bonds .or .grounds . .The .815 .Hz .reading .indicates .
that .the .815 .Hz .frequency .is .in .use . .The .815 .Hz .is .the .lower .frequency . .It .is .less .susceptible .to .
locating .errors .caused .by .adjacent .cables .or .pipes . .Also, .by .using .the .815 .Hz .frequency, .
the .locating .range .is .greater . .The .8 .kHz .and .33kHz . .are .mid-range .frequencies .used .when .
