Amprobe AT-4000 Advanced-Wire-Tracer - Manual (Page 7)

A2202 Clamp-On Transmitter Accessory
Enables the T-4000 to induce its signal onto an unenergized or energized circuit. Plug
the A2202 into the T4000 and clamp it around any conductor in an unenergized circuit,
or the hot wire in an energized circuit. The signal will be induced on top of the 50,60,or
400Hz frequency which may be present. The AT2201 acts like a 1/2 Volt battery when
clamped around a conductor. On a complete circuit this voltage will cause about 80mA
of current to flow on top of the whatever frequency is present.
To increase the signal strength, loop the wire around the clamp a few times or use the
B2024 battery Pack. The A2202 will allow wire tracing without the need for
direct connection. (Note: When using the battery booster (B2024 or B2025) the unit
will work in ultra high “U-HI” mode only. Remove the battery booster to return to
normal operation.)
