The SMART transmitter
The SMART transmitter is designed to generate Grounded Circuit signals and Open Circuit signals. The grounded and the open circuit signals are
very different from each other, so it is very important to understand the differences in each signal type. (see “Characteristics of the Short/Ground-
ed Circuit Signal” pg.. 8 and Characteristics of the Open Circuit Signal” pg..9)
Power Lead
The 20 ft. power lead of the SMART transmitter supplies power by connecting directly to the vehicles
battery and the long length provides easy access to circuits throughout the vehicle. The RED clip
connects to the positive side of the battery and the BLACK clip connects to the negative. It can be
connected to a power source from 12 to 42 volts.
Signal Lead
The signal lead with green banana jack, plugs into the assortment of adapters, probes, and clips that
are provided for you in the ECT-2000 kit. These accessories simplify connecting to your circuit.
Tone On/Off - Toggle Tone
“Tone On/Off” button toggles the tone of the SMART transmitter’s speaker on or off.
The toggle tone feature of the SMART transmitter gives you the ability to detect changes in the circuit
to detect intermittent problems. (See “Circuit Wiggle and Flex Test” pg.. 26)
Self-Test
The area located on the face of the SMART transmitter, with the words “Place receiver pick-up in this area to self-test” is used for testing the
SMART receiver.
