Sync Type
The user can set the Hexcorder Pro to perform in three different synchronization modes
• GPS synchronized, for synchronized timing with GPS enabled interrupters
• High/Low synchronized, for using non-GPS interrupters
• Unsynchronized, for non-interrupted surveys
Units
The user can display and record chainage for the CIPS survey in Metric (meters) or Imperial (feet).
Only applicable to surveys with CIPS.
Trigger
The user can set the Hexcorder Pro to be triggered in one of three ways
• Pushbutton trigger – The reading will be activated by pressing the survey pole button
o Most common selection, allows the surveyor to check the reading is accurate
prior to saving
• Time – the reading will be activated by the passage of a user-selected number of cycles
o Takes the reading regardless of half cell position and accuracy
• Distance – the reading will be triggered when the chainage increases/decreases by a
user-selected amount
o If moving fast, will only take 1 reading per interruption cycle, even if
surveyor has travelled 2 to 3 times the distance specified.
It is always recommended that surveyors begin with the Pushbutton trigger until they are used to the
equipment and survey techniques. If an automated survey is desired, it is recommended to automate
based on Time rather than Distance. This provides a reading based on the interruption cycle.
Readings based on Distance can be missed if the surveyor is moving faster than the cycle.
Start
Set the starting chainage. Only applicable to surveys with CIPS. This information can be found for
many test points from the official pipeline map.
Direction
User can set the chainage to count upwards (increment) or count downwards (decrement). Only
applicable to surveys with CIPS. The surveyor can walk upstream from a test point, return and then
walk downstream with the chainage calculating correctly.
