3.1.2.1 Battery Charging
To fully charge the battery, connect the instrument to the external DC charger
without activating the power on process. The length of time it takes to recharge it
depends on the condition of the battery. If they are very low the recharging period is
about 5 hours. The
CHARGER [4] indicator should remain lit.
When the battery charging process is completed with the instrument off, the fan
stops.
IMPORTANT
The instrument battery needs to be kept charged between 30% and 50% of its
capacity when not in use. The battery needs to be fully charged for best results. A
fully charged battery undergoes temperature-related discharge. For example, at a
room temperature of 20
°
C, it can lose up to 10% of its charge over 12 months.
3.2 Installation and Start-up

operating, it is also possible to select the
auto power-off mode by means of the
Preferences menu [22] and to select the time out until the automatic power-off.
When the equipment is going to be moved, activate the Transport mode by
means of the Preferences menu [22] to disable the power on process until one specific
