Charging the Battery
ProBER 2 contains high-capacity Nickel Metal Hydride (NMH) rechargeable
batteries.
ProBER 2 is supplied with a 15 V dc charger unit which requires an ac power
supply between 100 and 240 V, at frequencies between 47 and 63 Hz.
Always use the dc charger unit supplied with ProBER 2 for the shortest charge times
and best capacity. Performance limitations and damage may occur if other dc charger
units are used.
Before use
Before using ProBER 2 for the first time, it is recommended that you:
• Power up ProBER 2 and allow it to discharge completely.
• Charge the batteries until the battery gauge shows full charge. This normally
takes about 5 hours but can take longer if ProBER 2 has been in storage for a
prolonged time and the batteries have discharged well beyond their normal
operating range.
When using ProBER 2 after its first charge, allow it to fully discharge before next
recharging.
During the charging cycle some heat may be apparent on the case of ProBER 2. This
is normal and is due to the fast charge applied to the batteries.
Normal Use
Normally the batteries will be fully charged after 5 hours. It is good practice to
allow a 1 hour rest period after charging to allow the battery chemistry to stabilize
and obtain the highest battery capacity.
The longest time between charges is obtained in
measurements running.
The following functions reduce the operating hours:
