Locating Push Camera Cable Quick Guide

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.
Make sure the leads are not going to impede the operation of the turning pushrod cable cage.
If there is not a suitable area to insert the ground rod into the earth, it may be that the manhole access point has a metal
surround around the hole. It should be possible to make a good connection by clipping onto the surround. If the surround is rusty,
use a wire brush to clean the connection point first.
3. Select 83.1kHz frequency on the transmitter. (If 83.1kHz is not available on the transmitter, select 65kHz or 32.8kHz)
4. Insert the pushrod into the pipe and push in at least 5m (15ft) of the pushrod cable. (less than this may not provide enough signal)

Locating the Pushrod Cable
(connect to the reel as described above)
5. Use the "Mode" button to choose the Line mode. The peak icon
should be showing in the top left portion of the screen, and
the screen should look similar to the illustration below.
6. Use the "f" button to set the locators frequency to that of the transmitter.
Note that the screen will now show the addition of a compass (line direction indicator). In the presence of a locate signal, the
compass will align itself parallel to the pushrod cable being located. When the compass indicator is parallel to the pushrod cable,
the circle will be filled in blue. This ensures that the operator is aware of the direction of the pushrod cable.
7. Stand approximately 5m (6ft) from the reel and over the suspected position of the pushrod cable.
