1.2 Definitions
Zero distance:
Your survey needs to accurately record the distance of the camera from the starting
manhole so that pipe defects and features can be accurately located. However, in most cases you will
need to unwind the pushrod some distance so you can deploy the camera down into a manhole before
starting the pipe survey.
To ensure camera distances are recorded accurately in your survey videos and observations, you
need to zero the camera distance (‘set a zero distance’) when the camera is in position before you
start the survey. See
page 169
where this is described for pushrod systems and the same principle
applies for crawler systems.
Setting a zero distance is also known as
zeroing the cable
or
rod counter
.
Crawler and tractor
: both these terms are used in this document to refer to the motorized, wheeled
vehicle that is used to transport a camera.
