CountPlus Operating Instructions

Basic Operation

With the SeeSnake connected and powered on, use the Distance Key

and the Time Key

to set the display with the information you prefer.

a) The Time Key will toggle the display between Date, Date and Time, Time,

or No Date or Time displayed. Press the key once for each step through

the choices.

b) The Distance Key will toggle the display of distance on the screen

between on and off.

c) The distance counter will show the distance in the units set in the Tools

/Units

menu (see Units of Measure above).

(Distance measured from system zero-point)

System Zero-Point and Local Zero Point

The counter, as shown in Figure 15, starts from zero when the system is

powered on. This is called the system zero-point. You can change the physi-

cal point the system measures from by powering the system off, running the

cable in or out to the desired zero point, and powering on from that point.

The counter resets to zero when the system is powered on again.

Resetting the System Zero-Point You can 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.

Local” Zero-Point In addition, while it is operating, the CountPlus can be

made to also start counting from any custom “local zero-point” you select

with a second 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 dis-

tance 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) Pressing the Zero Key

will now toggle the display between the

default count and the new [0.0] point.

b) Once you start measuring cable feed from a custom zero-point, do

not press the Zero Key again until you have completed the measure-

ment you are working on, as pressing it will reset the custom zero-

point again and lose the measurement you have been taking.

c) As a precaution you may want to write down the system measure-

ment’s initial value just before setting a new zero point. (This will

enable you to compute the distance manually using the system count,

if you reset the local zero-point accidentally).

2) The CountPlus will continue to count the distance the cable is extended

and display the current total (if the display of distance is toggled on) from

the system zero-point or from the current local zero-point, if one has been

set.

3) The system zero-point of the CountPlus may be reset to zero at any time

by a long press on the Zero/Select Key (greater than 3 seconds). All

future system counter measurements until power-down will be based on

this new system zero-point. This will also reset the local zero-point.

How the CountPlus Measures
Distance

The CountPlus uses the movement of two magnets embedded in the mount-

ing plate behind the CountPlus unit. The rotation of the cable reel causes

these magnets to change orientation relative to the CountPlus, and this

change is detected by Hall-effect sensors in the CountPlus. An embedded

computer uses these sensor responses to compute the linear distance, tak-

ing into account the size of the reel and the size and length of the cable.

The CountPlus sets its “system zero” reference point on powering up, follow-

ing a configuration check. For most accurate results the cable should be fully

in the drum and the camera in the guide hoop when powering up. Otherwise,

varying degrees of slack in the extended cable can distort the measurement.
