EOC-BA-e-1711 216.2.1 Scope of deliverySerial accessories:• Terminal• Platform• Mains adapter• Protective cover• Support base/Wall fixture• Operating manual6.3 Mains connectionPower is supplied via the external mains adapter. The stated voltage value must bethe same as the local voltage.Only use original KERN mains adapters. Using other makes requires consent byKERN.6.4 Rechargeable battery operationBefore the first use, the battery should be charged by connecting it to the mainspower supply for at least 12 hours.When the symbol keeps flashing on the display, please charge the batteriessoon.6.5 Connection of peripheral devicesBefore connecting or disconnecting of additional devices (printer, PC) to the datainterface, always disconnect the balance from the power supply.With your balance, only use accessories and peripheral devices by KERN, as theyare ideally tuned to your balance.6.6 Initial CommissioningIn order to obtain exact results with the electronic balances, your balance must havereached the operating temperature (see warming up time chap. 1). During thiswarming up time the balance must be connected to the power supply (mains,accumulator or battery).The accuracy of the balance depends on the local acceleration of gravity.Strictly observe hints in chapter Adjustment.6.7 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. Toreceive accurate measuring values it is also recommended to adjust the balanceperiodically in weighing operation.
