6: Initialization warning
By default, this warning icon appears every minute. When it appears, a probe initialization is
required. If the probe is not initialized after 30 seconds, the message Please initialize the probe to
continue will appear and the readings will stop. The readings will resume when the probe will be
initialized (you just need to press on the INITIALIZE icon). It is possible to change the time between
two initializations in the System Configuration menu of the Toolbar (see Section 10 - Toolbar).
7: Probe low battery icon
This message indicates that the charge of the AA batteries is not sufficient to supply the probe.
The batteries must be replaced. When the level of the batteries charge is low, the value of the
readings could be inaccurate.
Recommendations:
 Keep a constant speed to move the probe along the core sample to obtain a real output graph,
and make sure that the contact between the core and the end of the probe is the same for each
reading you take.
 If the conductivity of some points on the core seems to be very high (999999), check if this
conductivity is true by reading again slowly the conductivity of these points with the MPP probe.
