The unit has two charging modes:
- fast charging mode : battery recovers 90% of its capacity in 3h ;
- service charging mode : this mode is initiated at the end of the fast charging mode, or before
when the battery is very low, or during a measurement if the adapter is connected.
Note : The charging mode (fast or slow) is determined by the unit, on the basis of the remaining
battery charge and the ambient temperature).
Notes :
→
If the 5-position rotary switch is set to the "OFF" position while the battery is being charged, the
"Bat. chrg." message is displayed if the unit is performing a fast charge and the battery level symbol
flashes. The "Bat. Full" message is displayed once the battery is fully recharged.

If the unit is used while it is being charged, only the battery level symbol will flash while the battery
is charging.
