6: PLEASE INIT message
By default, this message appears every minute. When it appears, a probe initialization is required.
If the probe is not initialized after 30 seconds, the GDD logo with the message PLEASE INITIALIZE
will appear and the readings will stop. The readings will resume when the probe will be initialized
(you just need to press the readings space). It is possible to change the time between two
initializations in the REINIT page (see Section 10.3). If you are not able to initialize the probe when
you see the GDD logo, you will need to close the software and open it again.
7: PROBE LOW BAT message
This message indicates that the charge of the AA batteries is not sufficient to supply the probe.
The batteries must be replaced or recharged. When the level of the batteries charge is low, the
value of the readings could be inaccurate.
Recommendations:
• Make sure that the contact between the core sample and the end of the probe is the same for
each reading you take. Otherwise, you will obtain different values if you repeat your reading with
a different angle or a different position of a couple of millimetres (see Section 13 - Reading
interpretation).
• Create a file after each reading series. (See Section 10.4 – Memory page).
