7. Before attaching any of the conductors, make sure the voltage presence is not beyond the
range of the instrument.
8. When not in use, keep the instruments in their carrying case.
9. If the CT-326-C will not be used for a period of time, remove the battery to prevent leakage
in the instrument.

T300 (6-300 V) Transmitter
�CAUTIoN: Do not connect the transmitter to a separate ground in electrically susceptible
patient areas of a health care facility.
�CAUTIoN: Make the ground connection first and disconnect it last when using the pigtail
connector.
The T300 Transmitter is designed for tracing 6-300 V ac or dc circuits by drawing a high
frequency load currents from a power source, thus creating a traceable magnetic field around
the conductors supplying its power (see Fig. 2). The transmitter houses a crystal controlled digital
circuit that never needs adjusting, and will not interfere with sensitive electronic equipment on
the line.
Transmitter Signal
When properly connected to the circuit to be traced, the red LED on the fuse end of the
transmitter blinks at a steady rate of 71 times per minute. This indicates that the transmitter is
operating, and that there is power on the line.
P26 Receiver
The P26 Receiver is a tuned magnetic field strength meter. When waved over conductors or
circuit breakers, the sensor in the receiver's tip ignores other line current fluctuations and
identifies the conductors feeding power to the transmitter.
The probe provides both audible and visible indications when it's within range of the wires or
circuit breakers supplying power to the transmitter. The audio indication is a 3.125 KHz tone. The
visual indication is provided by a 10- position LED display. An earphone is included for use with
the probe when background noise makes the audio indication difficult to hear.
