Introduction This guide describes using the VM-550FF 1-watt, and the Loc3-5Tx 5-watt transmitters to locate the pushrod cable on the Type-MX and Type-CP cable reels. The locator being used is the vLoc3-Cam receiver, but users of the full range of Vivax-Metrotech locators will also find it useful.

Locating Push Camera Cable Quick Guide The Loc3-5Tx Transmitter is a multi-frequency 5-watt transmitter. When using this model transmitter, only frequencies above 65kHz should be used. The locate frequency can be applied by direct connection or induction. For this application, the direct connection method must be used.

Locating Push Camera Cable Quick Guide Method: • Applying a signal 1. Connect the red lead to the reels connection post. 2. Connect the black lead to a suitable ground such as a ground stake inserted in the soil. If possible, place the ground stake at right angles to the suspected pipe direction as the earth lead may interfere with signals coming from the Pushrod cable.

Adjust the sensitivity control, using the "+" and "-" keys, so that the bar graph is at approximately 50%. 10.

This is to be expected and typically will happen a meter or two (3-6 feet) from the camera head. At this point, the signal will start to be distorted, and the depth measurement will be affected.

A Sonde icon will soon appear (Note that the arrow is not shown when the sonde icon appears). Keeping the locator vertical, carry on walking toward the Sonde until it is positioned on the crosshairs.
