Charging The Battery - Waltron 9065C Instruction Manual

Operation

CHARGING THE BATTERY

4.7
The battery level bar is divided into 5 blocks. They are all visible when the battery is fully
charged. When the battery level bar shows a remaining charge of less than 20%, the battery pack
must be recharged.
When 20% is remaining, the battery still has enough charge to carry out several measurements
before the display turns off and no more measurements are possible.
Procedure:
1. Remove the protective cover from the charging/communication connector.
2. Insert the charger's plug into the connection at the rear of the 9065C.
3. Connect the charger to the mains power.

While charging, the battery level bar moves to show that the battery is being charged.
4. Disconnect the 9065C from the charger after approximately 6 hours.
5. Refit the protective cover to the back of the 9065C.
If the battery is completely discharged, it takes approximately 6 - 8 hours to recharge the battery
pack using the charger. The 9065C has an internal regulator to control the charging process and to
protect the battery against overcharging. The battery is also protected against overheating, so the
9065C can be recharged for an unlimited time. However, the lifespan of the battery will be
increased if the recharging time is limited to 24 hours or less.
WARNING!
To avoid a short circuit, never insert metal objects into the "SFE".
NOTE:
Quick-charger (optional)
A quick-charger is available as an optional extra and can be used to charge the battery pack
separately.
Procedure:
1. Use the tools from the service set to remove the battery pack's two attachment screws at
the rear of the instrument.
2. Remove the battery pack horizontally from the 9065C.
3. Connect the quick-charger to a plug socket.

The LED on the quick-charger will be lit red.
4. Connect the quick-charger to the connector inside the battery pack.
25
The charging connector at the rear of the 9065C must never
be open when the 9065C is not connected to the charger.
Always place the protective cover on the connector when
the charging cable is disconnected.
The battery pack has a limited lifespan (see Section 7.2).
