Function
ON/OFF
Controls the power to the unit and sensors. Press to alternately apply
and remove power. When the display is blank, the power is OFF. When the
display is active, the power is ON. A short delay is incorporated.
Caution:
If power is removed during memory access operations when
the screen displays: ‘Saving’, ‘Deleting’, or ‘Please Wait’, then memory
corruption can occur and data loss is possible. See
Power Loss
for
more details.
ENTER
Starts the operation of the menu item displayed on the top line against the
> cursor. It is also used to progress to the next operation if requested by
a displayed message when static information is shown, or to confirm the
operator’s selection. If in doubt, press
ENTER
to continue and
ESC
to go back.
ESC
(Escape)
Exits a procedure and returns to the previous menu or operation.
(up/
down
arrows)
Scroll through the menus to set the required option to the top cursor line,
before starting the operation with the
ENTER
key.
STEP
Step through the available options for each of the operating parameters.
Note:
With the exception of the
ON/OFF
key, the required action occurs only when a key is
released after being pressed.
Note:
External push buttons are provided on the beam for use as optional
ENTER
(green)
and
ESC
(red) keys. These are particularly useful in the survey mode and during setting up.
They provide control of the data collection, and interruption during surveys and setting up
without moving the hand from the beam.
Note:
A menu may offer an action which is not valid at that time, for example moving back
one line when at the start of the first line. If a non-valid menu selection is made then the
data logger will bleep and take no action.
11. Grid Mode
Connect the data logger to the gradient sensors and battery, and then press and hold the
ON/OFF
switch until the display is activated. At switch-on the display will show the title screen with the
program version and battery voltage for a few seconds, before switching to the Mode Selection
Menu. You can then select either
GRID MODE
or
NMEA MODE
.
Note:
To change between Grid and NMEA Modes, the data logger must be restarted by
turning off/on.
