NOTE! When using with the microEXPLORER Cam-
era Monitor if the counter information is not
visible on the screen try zooming the image

the microEXPLORER Camera unit.
System Zero-Point and Local Zero Point
The counter, as shown in Figure 25, starts from zero
when the system is powered on. This is called the system
zero-point. You can change the physical point the system
starts measuring from by powering the system off, running
the cable in or out to the desired starting point, and pow-
ering on from that point. The counter resets to zero when
the system is powered on again.
Resetting the System Zero-Point: You can also reset
this system zero point at anytime with a long press (> 3
seconds) on the Zero Key. It is good practice to do this, for
example, at the entrance to a pipe.
Setting a Local Zero-Point: In addition, while it is oper-
ating, the SeeSnake can be made to also start counting
from any custom "local zero-point" you select with a sec-
ond counter.
1. To begin a separate distance count from a selected
point, such as a junction within a pipeline, press the
Zero/Select Key briefly. The distance display will
re-set to [0.0]. The square brackets indicate that you
are measuring from a local zero-point rather than
the system zero-point.
a. Once you start measuring cable feed from a local
zero-point, do not press the Zero Key again until
you have completed the measurement you are
working on, as pressing it will reset the custom
zero-point again and lose the measurement you
have been taking.

b. As a precaution you may want to write down the
system measurement's value just before setting a
new local zero point. (This will enable you to com-
pute the distance manually using the system count,
if you reset the local zero-point accidentally.)
c. Once you are finished measuring, pressing the
Zero Key will now toggle the display back to
the system count or create a new local [0.0] point.
Getting Consistent Measurements
Make sure all the cable is in the reel before powering up
the system. Wait for the initialization screen to disap-
pear before moving the camera head from the guide
hoop. This takes about 10 seconds.
Avoid moving the reel once you have started your mea-
surements.
Make sure the cable length, cable diameter and drum-size
settings are correct for your system.
If the system is shut down or loses power for more than
10-20 seconds the SeeSnake microReel may re-zero its
system zero point of reference, and any local zero-point
count will be lost.
When spooling the cable into the drum, maintain a uniform
friction or drag on the cable to ensure it does not bunch up
in the drum.
Accuracy In general use, the SeeSnake reported dis-
tance will be accurate to within 3 feet (1 meter). This ac-
curacy depends on cable tension, correct reel settings and
other factors.
For greatest accuracy:
1. Make sure the camera head is in or nearly in the
guide hoop when powering up. This ensures the dis-
tance computing is done from a full reel.
2. For measurements starting from somewhere other
than the reel, such as the head of a drain line, reset
the "system zero" point with a long press (> 3 sec-
onds) on the Zero Key, or use the "local zero" option
(by pressing the Zero/Select key) briefly, rather than
