Measurement Considerations

• Ensure that the camera lens cap is removed before inserting the
probe into the pipe.
• Store the lens cap safely while it is removed.
• For protection, attach the lens cap when storing the camera.
• After connecting the probe to the HDV700, verify that a clear
camera image is displayed. If not, or if the image is flickering or
otherwise compromised, remove the probe and reattach it.
• Turn the probe wheel slowly when moving the probe through a
pipe. Do not force the wheel if resistance is detected. Check the
nature of the resistance and clear as necessary before
continuing.
• Use the distance gauge to keep track of the probe travel dis-
tance. Zero the display when you first insert the probe into the
pipe for best accuracy.
• Take still images and video, adjust display parameters, and more
from the HDV700 touch screen (refer to the HDV700 user
manual).
• When the inspection is complete, carefully recoil the probe
slowly onto the storage wheel.
Cleaning
Clean the probe with a damp cloth and mild detergent as necessary.
Clean the camera, mirror, and worklight lenses, using a high quality
lens cleaning fluid and a lint-free swab.
