POWER SUPPLY
The instrument may be powered by alkaline or rechargeable batteries or directly from the main line.
OSP
uses 4
batteries type AA that are located inside the base of the handle.
7.1
Rechargeable batteries
The rechargeable batteries are shipped with an average level of charge. After unpacking, a full charge of the batteries is
recommended. Connect the instrument to the charger module (“OFF” condition) for a period of 10 hours minimum.
The Ni-MH rechargeable batteries do not suffer when used in cyclic operations. The cyclic operation is understood as a
method of operation by which the battery is continually charged and discharged.
Avoid leaving the instrument, with batteries totally or partially discharged, for a long time without recharging them.
To charge the batteries use only the original supplied charging module. The module incorporates protection and current
limiting devices not normally found in other commercial chargers.
The external battery charger is configured, before shipment, for a supply voltage of 115 Vac, upon order specification.
The nominal voltage value is indicated on the front label of the charger.
7.1.1
How to maximize the life span of the battery
Disconnect the ac mains supply when the battery is charged. Use the battery until it is completely discharged. Leaving
the ac mains charger plugged in during operations will decrease the life of the Ni-MH batteries. Keeping the battery
terminal clean will help maximize the operating time. Periodically wipe the positive and negative terminals with a dry
cloth. Removing and replacing the batteries will ensure electrical contact. This should be done when using a battery that
has not been used for a long time.
Note that the operating time decreases at low temperatures. A Ni-MH battery can be recharged about 500 times when
used with the recommended instructions. When replacing the Ni-MH batteries with a new set always replace
simultaneously the four pieces.
7.2
Power supply with alkaline batteries
Power supply with alkaline batteries must be specified with the order.
7.3
Power supply from main line AC
The battery charger module can be used to power the instrument for continuous operations from main line AC.
Rechargeable batteries or alkaline batteries are not required to be removed with AC power supply.
