  • Page 11: Basic Safety Precautions

    5.1 Pay attention to the instructions in the Operation Manual Carefully read this operation manual before setup and commissioning, even if you are already familiar with KERN balances. 5.2 Personnel training The appliance may only be operated and maintained by trained personnel.

  • Page 12: Unpacking

    If electro-magnetic fields or static charge occur, or if the power supply is unstable major deviations on the display (incorrect weighing results) are possible. In that case, the location must be changed. 7.2 Unpacking Carefully remove the balance from the packaging and setup balance at the intended workstation.

  • Page 13: Setup

    Before connecting or disconnecting of additional devices (printer, PC) to the data interface, always disconnect the balance from the power supply. With your balance, only use accessories and peripheral devices by KERN, as they are ideally tuned to your balance.
