TRANSMITTER -Tx

Internally, the transmitter has a fuse in

line with the line(hot) wire.

The voltage present on these terminals

( input wires) is rectified and an internal

power supply is created from that voltage.

That internal power supply, supply all the internal

circuitry. The transmitter uses an 1 OkHz, short pulse

oscillator to drive a mos-fet transistor which in turn will

draw current at an approximative 1 OkHz frequency.

This is the current which will be utilized to sniff the

wires or circuit breakers.
