Back one trav
Pressing ENTER once will cause the displayed position number to
return to 1, ready to start the traverse again. Further operations of
the ENTER key will cause the traverse number to be decremented.
If the option is selected before starting a line, the traverse number
will be decremented each time ENTER is pressed. When the required
number of traverses have been deleted, pressing Esc will return
the unit to the Survey Mode ready to continue from the start of the
selected traverse. This option allows the survey to be restarted from
the beginning of any previous traverse. If Traverse 1 is reached, the
unit will bleep and prompt the operator to start the line.
Back one posn
The Position number shown with the menu item is decremented
each time ENTER is pressed. When the required position has been
reached, pressing Esc will allow the survey to continue from that
position. When Position 1 is reached, the unit will bleep and prompt
the operator to start the traverse.
Enter dummy at
Inserts a single dummy value each time ENTER key is pressed. The
Position number shown will be incremented accordingly.
Note: Remember that if data is being recorded at 0.25m
intervals then four dummy values are required for each metre
of traverse. If a dummy is entered at the last position of a
traverse, the unit will bleep and prompt the start of the next
traverse.
Delete this Grid
The ENTER key will cause the current Grid to be deleted after
confirmation and the display will return to the main menu.
Esc/PB to connue
The display will always show the next position to be measured and
prompt the operator to press ENTER to start. If possible the operator
should follow the same procedure as at the start of the traverse, as
the recording will continue at the same pace when the ENTER key is
released.
Note: It is possible to carry out surveys with irregular boundaries or obstructions by using
dummy values in a Grid, and using different sized Grids. Dummy values can be transposed
to any other value when downloading to a PC.
18.1.1. Data Logging and Control
Data is collected at a fixed rate and is automatically saved to the flash memory at the end of each
traverse. If a survey is interrupted by loss of power, the data logger should continue from the start of
the interrupted traverse when power is restored. See Power Loss for more details.
Note: Power should not be deliberately removed during a survey.
