the white dot on the probe connector with the white
dot on the HDV700 connector and then pushing
the probe into the HDV700 cavity until it seats
firmly.

Tighten the collar nut to secure the connection. Do not overtighten.

The steps below explain how to safely connect the HDV700 Video­Scope with the probe. Always switch the HDV700 power off when
making connections.

Attach the HDV700 to the reel.

wheel stopper.

Recoiling the Probe

After coiling the probe onto the wheel, affix the
camera head on the camera head stopper.

Ensure that the wheel stopper is secured.

Loosen the wheel stopper.

Carefully coil the probe back onto the wheel

Tighten the screws.

Distance Gauge

1. Backlit digital display shows probe travel
distance

2. Power/Reset button. Press for 3 seconds to
switch ON or OFF. Short press to reset/zero
the display

3. Unit of measure button (meters and feet)

4. Display backlight button

5. Battery compartment cover

6. Battery compartment screw

7. Battery status

8. Unit of distance measure (meters)

9. Unit of distance measure (feet)

The probe includes a brush accessory that assists the probe as it
moves through the pipe under inspection. The brush can clear de­bris that may impede the probe. The brush diameter is 4 in. (100
mm).

Position the mounting ring so that it aligns with the
screw holes.

The electronic gauge measures and displays the distance that the
probe travels into the inspection area. The gauge tracks forward
and reverse movement.

Powering the Distance Gauge

The distance gauge is switched ON or OFF by pressing the power
button (2) for three seconds. After one hour, the gauge will auto­matically switch off, to conserve battery energy.

The battery status icon (7) shows the current battery power. To re­place the batteries, follow the steps below:

1. Switch the meter off by pressing the power button (2) for three
seconds.

2. Remove the battery compartment screw (6).

3. Remove the compartment cover (5).

4. Remove the old batteries and dispose of them responsibly.

5. Install the two new AAA batteries, observing correct polarity.

6. Close the compartment and secure it with the compartment
screw.

Change the Measurement Units

The display shows the probe travel distance in meters (m) and feet
(ft), short press the units button (3) to toggle the displayed units.

Reset (Zero) the Distance Gauge Display

With the gauge powered, short press the power/reset button (2) to
reset the display to zero.

For the best accuracy, zero the display at the point of probe entry
into the inspection area.

If you wish to set a reference point, other than the starting point,
press the reset button at any time during an inspection. Now you
can monitor the distance travelled from this new reference point.

Distance Gauge Backlight

Short press the backlight button (4) to switch the display backlight
ON or OFF. The backlight will automatically switch OFF after 10
seconds to conserve battery energy.

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.
