Note: When the ST-33Q+ is powered on and in Direct Connect Mode, only hold the cable leads by the plas­tic sheathing. Do not touch the metal scraper tip, teeth, or magnet.

  1. With one cable lead attached to the ground stake and the other attached to the target conductor, press the Power key to power on the ST-33Q+.

 Upon start up, the ST-33Q+ measures the current flowing through the target conductor and beeps to indicate output. Faster beeps indicate a higher out­put current.

  1. Select a frequency by pressing the Frequency key until the desired frequency appears or press­ing and holding the Frequency key to show a list of available frequencies. Press the Up and Down Arrow keys to move through the list. When the desired frequency is highlighted, press the Select key to activate it.

Note: In addition to the default frequencies, the ST- 33Q+ can also accept custom frequency settings up to 490 kHz. See the section on adding custom frequencies in the Operator’s Manual for more de­tails.

  1. Follow the instructions in the receiver’s Operator’s Manual to power on and use the receiver. Ensure the frequency on the receiver matches the ST-33Q+. If the receiver signal increases when held near the ST-33Q+, it is correctly picking up the transmitted frequency.
  1. Adjust the current as needed during the locate by pressing the Up and Down Arrow keys on the ST-33Q+. In Direct Connect Mode, the ST-33Q+ in­creases the current as close to the following levels as possible:

25 mA

50 mA

100 mA (default)

200 mA

400 mA

  1. After completing the locate, press the Power key to power off the ST-33Q+.

Note: To reduce the risk of electrical shock, power off the ST-33Q+ before disconnecting the leads and remove the lead from the target conductor be­fore removing the lead from the ground stake.
