ST-305R with clamp

Use the ST-305R/ST-305 with an inductive clamp by following these steps:

1.  Before connecting the inductive clamp, confirm that the target conductor is not live and grounded on both ends, and that theST-305R/ST-305 is powered off. The ST-305R/ST-305 is not designed to be connected to live conductors.

2. Insert the inductive clamp plug into the jack on the ST-305R/ST-305 below the keypad.

3. Place the jaws of the inductive clamp around the target conductor, ensuring that they close completely. The LEDs on the clamp are lit when the jaws are closed and the ST-305R/ST-305 is powered on.

    • Note: In Inductive Clamp Mode, the ST-305R/ST-305 defaults to 50% power level to conserve battery power.

5. Select and set the same frequency on both the receiver and transmitter

6. Check the connections and adjust the current as needed during the locate.

7. When finished, press the Power key to power off the ST-305R/ST-305 before disconnecting the inductive clamp.
