    5 6. Safety warnings and cautions 6.1 do not connect fox jr or hound jr to any source of ac power. Ac voltages above 30 volts can be dangerous, and may result in user injury. The fox jr and hound jr are not intended to trace live ac power lines. The fox jr will be damaged if connected to a live ac p...

Under some conditions, unconnected wires may “float up” to dangerous potentials, and touching them may result in user injury. 6.5 use care when connecting the fox jr to any wire or cable. An unexpected dangerous voltage may b...

    7 6.7 do not use the fox jr or hound jr if either unit appears to be damaged. A damaged unit may lead the user to a false conclusion, resulting in user injury. 6.8 do not use the fox jr or hound jr if either unit is wet. A wet unit may result in shock or injury to the user if connected to live circu...

    14 use caution. Reduce the thumbwheel setting to reduce the feedback. Because the fox jr’s test leads are so short, the hound jr may not detect the warble signal more than a few inches away. When the fox jr is con- nected to longer wires, the hound jr’s sensing distance will improve. At high thumbwh...

    23 in a junction or wall box, use the hound jr to determine if the fox jr warble tone is present. If so, you may have found the cable you are looking for. You may find that several cables in different junction boxes produce similar strength warble tones. This phenomenon is caused by crosstalk . . . ...

    25 out, the case of the fox jr will still radiate some warble tone. Do not confuse this with the warble tone coming from the alligator clips. Perform a few experiments by shorting out the clips and probing the fox jr with the hound jr so you know what to expect. 9.1.5 tracing wires within a cable wh...

    28 circuits, adjacent to the target wire can act as shields, reducing the hound jr’s ability to sense properly. Spreading the wires apart will reduce the shielding effect and allow the hound jr to work better. Defects in a cable or wires, such as shorts or opens, will reduce the signal amplitude and...
