Using the A2202 Clamp-On Transmitter Accessory
The A2202 will allow non-contact signal indication onto energized or non-energized
conductors. On energized lines, the signal will propagate downstream to the end of
the circuit, provided there is a current flowing in the circuit. Unenergized lines must be
grounded at both ends or made into a complete circuit. The signal strength can be
boosted significantly by using the B2024 battery Pack. (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.)
One typical application for the A2202 is to access the hot wire at the panel in order to
identify the ‘downstream’ loads:
1. Plug A2202 into T-4000. Set signal level to ‘High’.
2. Clamp the A2202 around the ‘hot’ wire.
3. Set the R-4000 to ‘OPEN’ mode and trace the downstream wiring. To trace buried
lines, switch to ‘SHORT’ mode (
