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.

1.

Slide the transmitter power switch to the VOLTAGE

position. The POWER LED will switch on.

2.

Slide the Receiver power switch to the ON position. The

POWER LED and the SIGNAL OK LED will switch ON.

3.

Place the Romex

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.

4.

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.

5.

If desired, switch the receiver power

switch to the audio OFF position

to

disable the audible tone.

6.

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.
