Operation
Detecting Live Circuits (VOLTAGE method)
The RT30 can be directly clamped on installed building wiring
and will detect the voltage applied to the wiring.

Slide the transmitter power switch to the VOLTAGE
position. The POWER LED will switch on.
Slide the Receiver power switch to the ON position. The
POWER LED and the SIGNAL OK LED will switch ON.
Place the Romex
TM
/nm cable (AC wire) directly into the
wire clamp slot or, alternatively, connect the external
voltage detector probe into the external probe socket and
then clamp the probe to any cable, extension cord or
appliance cord.
If the cable is “live” (voltage present), the
VOLTAGE/LIGHT amber LED on the
transmitter will switch on and the
DETECT LED on the receiver will switch
on.
If desired, switch the receiver power
switch to the audio OFF position
disable the audible tone.

When the voltage is removed (by opening the splice or the circuit breaker,
for example), the Detect LEDs will switch OFF and the detect beeper will
switch OFF.
Note:
Use of the External Probe overrides the setting of the Power/Mode
Switch. The Lighting method cannot be used while the External Probe is
attached.

Expose the Light Sensor to the light source.
The VOLTAGE/LIGHT LED on the transmitter and the DETECT LED on the
receiver will switch on
When the lights are turned off the VOLTAGE/LIGHT LED on the transmitter
and the DETECT LED on the receiver will switch off, indicating the light has
been switched off and power has been removed.
