2.4.1 DESULFATION

Pulse system used to recover sulphated batteries by applying enough voltage to
neutralise the surface layers of oxide and revitalize the underlying plates. It is
advisable to perform this operation with the battery disconnected from the vehicle.

ATTENTION! Pay particular attention to the nominal voltage of the battery
which must correspond to the battery selected using the "BATTERY
VOLTAGE" button and indicated on the display (fig. A.1).
Procedure
– press the "MODE" button (fig. A.22) to select this function (fig. A.10);
– press the "BATTERY VOLTAGE" button (fig. A.21) to select the battery voltage
(fig. A.1);
– connect the clamps to the battery terminals;
– the process starts automatically, with a variable duration depending on the
battery response,displayed in graph format. If the desulfation process is
completed successfully the word "End"will appear on the display (fig. A.2). In
the case of highly sulphated batteries, hence irrecoverable, this process may not
be completed; this condition is indicated when the charge phase continues to
restart and the opening/closing of a relay is audible.
END OF PROCESS – EXAMPLE

2.4.2 EQUALISATION
