CWS-BA-e-0610147.5 Storage battery operation (optional)Installation:1. Disconnecting the power pack from the balance2. Unscrew both M3 screws and remove the cover of the battery compartment.3. Connect wires in the battery compartment to the batteryConnect red wire to positive (+/red) terminal and black wire to negative(-/black) terminal. Otherwise there is a danger of explosion.4. Insert battery in compartment and reattach the cover with the help of thescrews.5. Turn on the balance and check whether the balance is working normally.Loading the batteryUse the provided power pack for battery charging.Before the first use, the battery should be charged by connecting it to the mainspower supply for at least 15 hours.• The display [Lo BAT] indicates that the capacity of the battery is nearly ex-hausted. Connect the power adaptor as soon as possible to change the bat-tery.• Whilst working in battery mode, [ T ] will be displayed above the batterysymbol• It is possible to use the balance during charging• Charge the battery at a temperature ranging between 5°C and 35°C• Charge the battery at regular intervals (every 3-6 months), when the balanceis not put to use for a longer period of time.7.6 AdjustmentAs the acceleration value due to gravity is not the same at every location on earth,each balance must be coordinated - in compliance with the underlying physicalweighing principle - to the existing acceleration due to gravity at its place of location(only if the balance has not already been adjusted to the location in the factory). Thisadjustment process must be carried out for the first commissioning, after eachchange of location as well as in case of fluctuating environment temperature. To re-ceive accurate measuring values it is also recommended to adjust the balance peri-odically in weighing operation.ScrewsBattery“+” electrode red“ - ” electrode blackBattery compartment
